How to Install a Dual Indoor Grounding Receptacle

When doing a major renovation, people often start with the wiring. With a large number of electrical appliances, the question often arises - how to connect a double outlet to create more comfortable conditions. Their installation helps to avoid unnecessary communications, as well as additional sources, connections: tees, extension cords and carriers.

It often happens that connecting a double socket can cause some difficulties. This happens when there are no minimum skills or mistakes made in a hurry. To prevent this from happening, you need to prepare everything in advance and make sure that all the parts are available and that the outlet itself is in working order. In addition, there are many nuances that can affect a malfunction or short service life.

What is a double socket?

A double socket is a device in the form of a plastic case of different designs with a working part. Inside the case there are all the terminals, springs for the plug, contacts, and grounding elements that allow you to remove voltage from the devices and ensure their safe use. Modern sockets are available in the following types:

• French with a third additional pin,
• American, with side slits,
• double socket with cover for installation outdoors or indoors with high humidity levels,
• German with grounding contacts (common in Russia).

The case on the front side in the center has two recesses with holes for the plug pins. A single socket has one recess, a triple socket has 3. On the sides of the recess there are protrusions in the form of metal plates, and on the reverse side there are working elements. The double socket can be installed independently. It is better to plan the installation of electrical accessories during repairs, so that the socket can be slightly recessed into the wall using a socket box, i.e., make it “hidden”. If replacement is required after repair, then you can choose special compact models that are easy to use.

Connecting a double socket is not very complicated; a plastic cup is used for installation, and the structure itself is secured with bolts. First, the socket must be disassembled; first, the frame with the working mechanism is attached, using the previously installed socket box. The top of the structure will be covered with a decorative overlay cover. Before starting work, you must turn off the power to the apartment and take care of your own safety.

Errors when wiring the socket

And although installing an additional outlet is a simple task, beginners often make mistakes. Such an unfortunate misunderstanding as incorrect installation of a new electrical point can result in major troubles.

Therefore, it is important to pay special attention to the most common mistakes and try to avoid them. First, you need to use a wire to connect the new outlet that is the same thickness as the existing one. Otherwise, there can be no question of correct operation

Otherwise, there can be no question of correct operation

First, you need to use a wire to connect the new outlet that is the same thickness as the existing one. Otherwise, there can be no question of correct operation.

Secondly, it is advisable to use wires from the same material - if the socket is powered by a copper wire, then the second one from it should also be connected using a copper wire of the same diameter.

The third mistake made when connecting independently is violating the order of connecting the wires. To prevent this from happening, you need to clearly understand the purpose of each and correctly determine the place of its attachment.

For convenience, it is advisable to look at the old one by disassembling it before purchasing a new outlet. This is done strictly after turning off the power supply.

You should pay attention to the presence of a grounding wire - if there is none, which is often found in Khrushchev-era buildings and other old buildings, then it is better to take the wire for the new outlet without ground. The fourth mistake is an incorrect or insufficiently strong connection of the wires with the working mechanism of the socket

Here, without experience, it is quite difficult to find a balance

The fourth mistake is an incorrect or insufficiently strong connection of the wires to the working mechanism of the socket. Here, without experience, it is quite difficult to find a balance.

Therefore, in order to minimize the amount of work ahead, it is advisable to conduct a rehearsal for connecting the wires on a spare section of wires. You can use a light bulb to check the quality of the bond.

You can choose the most convenient option for fastening the wires together - you need to buy original terminal blocks or other products, fearing counterfeits

The fifth mistake was when the wire was run diagonally. This is unacceptable, and it is prohibited by electrical wiring standards - the wire should be laid vertically. Although home craftsmen are not yet capable of this.

You should not do this - if cosmetic repairs are carried out in a couple of years, then finding the exact location of the wire will be extremely problematic and it can be accidentally damaged.

The wires in the contact of the working mechanism should also be secured efficiently. You will need a screwdriver for this.

The sixth mistake, or rather, a nuisance, is an unsuccessfully chosen design of the decorative overlay of the socket. This point will not affect the performance of the mechanism in any way - it will only be conspicuous, standing out from the general design concept of the room.

To avoid such dissonance, you should select in advance the most suitable model that can harmoniously fit into the existing style composition.

It is now easy to choose a socket model that is suitable in color and shape - manufacturers are vying with each other to offer the most sophisticated options

It is important that the product does not turn out to be a fake. Knowing the main problem areas of the upcoming work on installing an additional outlet, it will be easier to avoid common mistakes

Of course, these nuances do not concern the work of professional electricians - the experts will do everything right the first time

Device installation features

A double socket has one socket box with two separated terminal blocks and one mounting part for wires.

A double socket is a monoblock consisting of two plug connectors, and therefore the diagram for connecting it to one socket box will be somewhat more complicated

If desired, the installation of an electrical point can be done on your own, without resorting to the services of a specialist.

The use of jumpers is allowed only if it is planned to connect not very powerful devices to the electrical points. When connecting powerful equipment, technicians recommend connecting two outlets in parallel, creating a branch of wires for each point.

But in any case, to prevent emergency situations, the total load on this type of outlet should be no more than 16A.

If it is necessary to install a socket with two different socket boxes, the niches for their installation will need to be pre-drilled with an electric drill, while maintaining the same distance between the holes.

Installation of socket boxes

Lead the wire into the socket box and install it in the prepared recess. For fixation in socket boxes, there are usually special fasteners (claws) that rest against the walls when the screws are tightened.

To increase reliability, fix the socket box with a solution (cement, plaster, alabaster, etc.), since standard fasteners weaken over time. All cracks should be carefully filled with solution.

The overhead double socket does not require preparation of the hole and installation of socket boxes, since it is mounted directly on the wall. Fixing overhead sockets is usually done with dowels.

When it becomes necessary to install a double socket

In some cases, a 2-socket outlet is a necessary measure, especially for apartments built in the mid-to-late last century. Their peculiarity was an extremely inconvenient arrangement of electrical appliances. In most cases, one of them ended up behind cabinet or upholstered furniture, and the owners had one point at their disposal in the corner of the room. Installing long external pads in such places is neither practical nor aesthetically pleasing. This will lead to the fact that over time a trail of wires will stretch to them that do not fit into the interior. The best solution in such situations is to install double recessed sockets.

The advantages of this solution are the following:

• The products have one body. There is no need to make inserts and jumpers using twists. The cable retains its integrity after installation and connection of the device.
• Common cover for both sockets. This is not only aesthetically pleasing, but also practical. To install covers when installing dual outlets, you will need to widen the holes in the wall to increase the distance between the mounting blocks. In any case, there will be a gap between the outer linings, which will not decorate the wall in any way.
• There is no need to drill a hole for a double socket box. Double designs fit perfectly into standard glasses in the walls. Their mounting blocks correspond to the dimensions of single products.
• Easy to install. Connecting a two-socket outlet is as easy as connecting a device with one input. The caliper and spring-loaded feet ensure precise positioning and strong fixation of the mechanism.

If the cable has a grounding wire, it is recommended to purchase internal double electrical sockets that have the appropriate contact. It is recommended to ground electrical appliances not only for safety reasons. Connecting this wire will allow you to get rid of the background noise and crackling noise produced by the speakers of household appliances.

Installation of double and triple sockets

There is no difference between how to connect a triple, double or single socket - all the steps are completely the same. Of course, all work must be performed with the electricity turned off:

• A hole is drilled in the wall where a socket box will be installed and a groove through which the wire will be fed (if installation is being done from scratch).
• Gypsum or cement mortar is prepared - just a little so that it is enough to secure the socket box in the wall.
• The socket box is installed flush with the wall (the wires are inserted inside it, and before that their ends must be wrapped with electrical tape so that the gypsum solution does not get on the wires). Then you need to wait the allotted time for the solution to completely harden - depending on the composition, this can take from 15 minutes to a day.
• Next, the insulating tape is removed from the ends of the wires, the required amount of insulation, if necessary, the wires are inserted into the contact mounts and tightened. Contrary to some opinions, there is no difference in how to connect a triple socket (the same applies to double and single) - the phase wire can be clamped both on the right and on the left contact. The main thing is that there is good contact between the core and the terminal; to increase its area, the core can be flattened a little with pliers.
• Then the inner part is installed in the socket box - there is no need to expose anything here, since it has a limiter with which it is pressed against the wall. When the socket is completely leveled, the spacer tabs are tightened and the limiter is screwed to the socket.
• The last step is to secure the cover - it is screwed to the inside with bolts.

At what step you need to turn on the electricity depends solely on the degree of curiosity - whether the connection was made correctly or not. You can check the voltage immediately after connecting the wires, after installing the internal part in the socket box, or after the installation is completely completed.

Rules for connecting a double socket

There are different options for connecting structures that include groups of sockets, switches or combined products. But the basis is always single devices for a single consumer, which can be anything, for example, a lamp, TV, iron or computer.

The most saturated room in a standard apartment in terms of the number of consumers is the kitchen. Especially if it is a small-sized “Khrushchev” or “Brezhnevka”. There is even room here for a washing machine, which does not fit in the combined sanitary unit. Nowadays the range of equipment used is so wide that 2-3 sockets cannot be used.

Modern kitchen sets hide behind their sparkling panels the most unique inventions that help make the housewife's work easier: • electronic or gas hobs; • dishwashers; • exhaust systems; • refrigerators, refrigeration complexes and chambers.

This is not counting microwaves, electric kettles, coffee makers and other small items. And they all require their own place of inclusion. The switching system has a two-story layout. The first plan is located at floor level, the second - at the height of a person of average height.

Important! Before you start connecting a double socket to one cable, you need to turn off the corresponding circuit breaker on the power panel, if there are several of them. If there is none, the general one is disabled.

Connecting wires to a double socket is carried out as follows. To check whether they are phase or zero, you need a simple tester in the form of a screwdriver with an indicator on the handle. If the indicator lights up when you touch the wire with a screwdriver, then it is a phase; if not, the wire is neutral. According to the rules, different colors of wires indicate ownership. Typically, brown is phase, blue is zero, and yellow and green are ground. Another rule is wiring connection. The phase is connected to the right terminal, zero to the left, ground to the central one, with the bracket.

The note! Dual sockets have a common power terminal. Current is supplied to each device through a distribution strip. At the same network voltage (220 V), the current strength for each device will depend on the power of the connected equipment. Although the socket is double, the load power will not double. It is imperative that the cable suitable for the outlet has a cross-section no less than that common throughout the house (the best option is the same). The core material must also match. If all the wiring is copper, then a copper cable is supplied to the device.

Dual Socket Installation Tools

To install a double socket you will need the following set of tools:

• A screwdriver that matches the screws that secure the socket
• Screwdriver coated with dielectric
• Cable (if you are installing an outlet and not replacing it)
• Hammer (also - if you need to install the socket in a new location)

Installation steps - do everything in order

Current is supplied to each device through a distribution strip. The cable is stripped of its insulation and the ends of the cores are stripped by mm. Without waiting for the plaster to acquire the desired strength, the sagging is removed with a knife. Programmable Equipped with a timer that allows you to set the time for automatic shutdown and on. Using only a wireless data transmission system is dangerous from the point of view of communication interception.

Using the same principle, the center of the second device is determined. RJ devices provide a computer connection to the Internet and local network.

Many people face a problem when they urgently need to connect a charger for their phone or tablet, but there is no free outlet. When installing a socket in a socket box, the wire is laid first, it is rolled into a ring or folded into an accordion, and then the working part is inserted, which presses the wire to the bottom of the socket box. They must be made of thick metal. The connection of wires to screw terminals is carried out by wrapping them around the clamp clockwise or by pulling them between two plates. For reliable fixation, an alabaster or cement mixture is used. The side screws are part of the fastening and serve to secure the socket in the socket box. How to connect a surface socket?

Types of double sockets

In addition to double sockets, there are also single and multi-socket ones. The type of equipment depends on the number of plug connectors included in it. Regarding the modification of the device, there can be two types:

1. Closed - devices that have shutters covering the contact part. Suitable for apartments where children live.
2. Open – standard type sockets.

Types of Dual Outlets
The product may or may not have a ground connection. Grounded outlets have grounding pins that protect electronics from power outages.

Equipment without grounding is installed in premises where it is not provided (offices, old residential buildings). In such buildings, connecting a structure with a grounding contact will not make sense, because there will be nothing to connect it to.

In modern houses and high-rise buildings, where grounding is provided, sockets with grounding are installed.

These types of devices are easy to distinguish.

Double sockets with and without grounding

There are designs protected from moisture, as well as dust and dirt.

Other types of structures:

• external;
• hidden (internal);
• standard;
• polar.

Connection

Nuances

If there is no grounding cable connected to the house, then the work of installing a double socket is much easier and faster. Here you only need to connect the wires without separation, and the difference in connection to specific phase and zero terminals does not matter.

If the apartment has grounding, then the number of wires increases from two to three. The work becomes more complicated - it is necessary to correctly identify and connect each wire. To make it easier to solve the problem, the wire insulation is painted in different colors:

• phase - red, brown or white;
• zero - blue, blue or black;
• grounding - yellow or green.

A distinctive feature of sockets with grounding is the need to connect the grounding to a terminal with “antennae” protruding beyond the plane of the housing. The connection of wires to screw terminals is carried out by wrapping them around the clamp clockwise or by pulling them between two plates.

The wire used must be made of the same metal as the wiring cable. For example, the jumper should be aluminum if the wiring is made of aluminum wire.

Installation of a double socket can be carried out either with or without grounding

Preparatory work

To carry out the work you will need to assemble the following tool:

• Phillips and flathead screwdrivers;;
• knife or scalpel for stripping insulation;
• electrical tape;
• pliers.

Before starting work, you need to de-energize the room: the machine levers in the panel are lowered to the “Off” position. At the location of the socket, the voltage must be checked again using an indicator screwdriver.

If there is voltage, this indicates that not all wires connected to the outlet are de-energized.

Therefore, it is important to turn off all machines

A double socket with grounding is installed if there is grounding in an individual house. It makes no sense to install grounding in urban high-rise buildings - the design provides for grounding in them.

Markings on the wall

The sockets are located close to the wiring or distribution box laid in the wall. The location for the future placement of the device is marked on the wall with a pencil.

A hole in the wall is made using a hammer drill and a special crown attachment

Before installing a socket with two “glasses”, you need to measure the distance of the drilled holes from one to the other. The axis of the first socket box is marked, and then the other. At the marked places, a recess is arranged with dimensions that allow free placement of the internal body of the device - the glass - in it.

A socket box is installed into the hole obtained after drilling to secure the device.

Drilling of holes is carried out using a nozzle - a crown, with a diameter several millimeters larger than the circumference of the socket. In this case, the recess should be arranged so that the installed socket box is flush with the wall.

Performing wiring and twisting

This type of work can be called the most responsible and requires special attention. The task is to connect the contacts and the power wire, for which the wiring is pulled to the socket from the box.

First you need to disassemble the socket into two parts: separate the mechanism and the panel.

The crown inserted into the hammer drill should be replaced with a drill, the diameter of which should slightly exceed the diameter of the wire or the cross-section of the corrugated pipe within which the wiring is planned to be placed. Ideally, the diameter of the cable and drill should match.

The main wire is inserted into the socket box through one of the existing holes, and the additional wire is inserted through another hole.

The wires are twisted inside the “glass”. But first you need to strip the ends of the wires from the insulation with a stripping tool that will not damage the cable or bite it

If there is no such tool in the apartment, the work can be done with a sharp knife or scalpel, cutting through the insulation in a circle and then carefully removing it. For ease of subsequent connection, it is recommended to slightly raise or lower the ends of the wire

The wires inserted inside the socket are carefully stripped and bent down or up

Preparing the wall

Installing a double socket is a little more complicated than a single socket and depends on the type of equipment:

1. To attach a double socket of a non-recessed (open) type, you only need to screw the housing to the wall with screws.
2. To attach the housing of a double socket of a recessed or internal type with distribution strips (described above as the first type of socket), you should drill one hole in the wall with a hammer drill with a special attachment (slightly larger than the socket box). If the wall is concrete, you need to use the hammer drilling mode. If the wall is made of brick or plasterboard, then only drilling. It is attached in the same way as a single one in one socket box.
3. To attach a double socket with parallel connection (described above as the second type), you must first drill one hole for the first socket. Then attach the device to the wall and mark the drilling location for the second socket using a level. Make a second hole. Next, you need to take a drill with a diameter slightly larger than the diameter of the corrugation for the jumper wires, and drill a hole between the two socket boxes.

New socket

First, a standard socket box is installed. It is always the key to a securely fixed socket. It is often also covered with alabaster or putty to increase the adhesion strength to the wall. Then all the cables are connected. The outer insulation is removed with a knife and a heel.

There is no need to leave too much wire. They have no purpose here. It will only interfere with the installation of the entire mechanism. The margin should not exceed 10 centimeters. If the wires were short, then they can be extended. Then strip the insulation from the conductive wires.

Double sockets with cover are no different from other versions. Only outwardly they look more aesthetically pleasing. Here the wires are connected in exactly the same way. The phase wire is always brown, the neutral wire is blue, the ground wire is green-yellow.

We unscrew the screws and install all the wiring in place, then tighten everything well. It makes no difference which terminal to install phase or zero on.

The most important thing is that they do not connect to the same contact. In this case, a short circuit may occur. The grounding connection is attached to the center contact, which is located on the bracket. Nearby you can see a grounding sign.

How to choose a good double socket

When choosing a product, you should pay attention to the following criteria:

• The size of the mounting box corresponds to standard holes in the walls. It is advisable to install a double socket in one socket box without carrying out additional drilling work to expand or deepen it.
• Degree of protection. For a family with no children, conventional models with an IP22 rating are sufficient. Products with degrees of protection IP33 and IP43 are equipped with curtains that protect the contacts from splashes and penetration of solid objects. For the bathroom and kitchen, it is better to take IP44 sockets, which are not afraid of splashes and streams of water flowing along the wall.
• Contact standard. You should stop at F or C. Products of this type are adapted for all types of plugs and are equipped with a contact for grounding.

The color of the product matters. It is not necessary to take standard white sockets. To decorate the interior in an original way, you can buy products in blue, red, yellow or any other color.

Preparatory work

The amount of preparatory work will depend on whether the outlet is being installed in a new location, or whether they simply want to replace an old regular outlet with it. Let's consider both options.

Preparations before replacing the outlet

If there is already an outlet at the installation site, it must be removed. This can only be done after disconnecting the outlet from the power supply. After turning off the machine, you need to use the phase indicator to check whether the electric point is really turned off.

Removing the socket

Dismantling the socket is carried out in the following sequence:

1. First, remove the front panel by unscrewing the screw holding it in place. Sometimes, to access the fastener, you need to pry off the plastic decorative panel, which is held on by a latch, with a flat screwdriver or knife.
2. Having gained access to the inside, unscrew the screws holding the wire strands in the terminals.

Next, all that remains is to unscrew the fastening that holds the base of the socket in the socket box.

Preparations before installing a new outlet

As part of the preparatory work, a wire needs to be laid from the distribution box to the installation site of the new electrical point. To do this, a channel is punched in the wall with a punch - a groove.

When the groove is ready, a wire is laid in it. It is best to place it in a corrugated tube. In this case, if the wire burns out, it can be easily removed and replaced with a new one without breaking the plaster.

Socket outlet

After laying the corrugated pipe with the wire, the groove must be covered with cement-sand mortar.

The wire is connected to the terminals of the junction box after installing the socket.

Now you need to make a recess in the wall in which the new double socket will be placed.

Existing connection methods

Sockets with more than two pieces are connected in three ways: in series, in parallel and mixed. Electricians use other terms - star (for the first option), loop (for the second). Before choosing one of the methods, you need to find out the pros and cons of each, and choose the one that is suitable for a particular apartment.

If the room has electrical wiring, it is important to consider the way the cables are routed and the total power available. New ones may exceed the limit; the wire will have to be pulled from the shield.

Parallel connection

The essence of the method is to connect sockets in one distribution block, which bears the entire load when the electrical equipment is turned on. A cable is pulled from the common house panel to the distribution box, and wiring is pulled from it to each power point (separate wires).

The advantage of this method is the independent operation of each power point and switch. If one device burns out, the others will continue to work. But if the main wire becomes unusable, the voltage will disappear completely. In such a situation, it is easier to find the gap and fix the problem.

Serial connection

A daisy chain connection means a sequential transition from the first outlet to the next. Instead of twisting wires, device contacts are used. The phase and neutral cables are connected to the first mechanism, then to the next and sequentially to the last.

The “pure form” method is rarely used. For example, if you need to install an additional socket or switch or move one of the devices some distance. In the second situation, they leave the old access point and lead from it to a new location - this way there will be less need to scratch the walls.

It is forbidden to connect devices with high power to sockets connected by a cable. Air conditioners, microwave and conventional ovens, washing machines and other similar devices must be powered from other access points. In a daisy-chain system, many outlets are connected to the same circuit, so the load falls on each one.

Mixed connection and grounding in series connection

If you decide to use a series connection of sockets, you can strengthen the overall design by using a mixed method. The essence of the method is as follows:

1. A central cable is connected to the distribution box from the common panel board.
2. In the preliminary wiring plan, the most distant point of access to power is selected.
3. The selected outlet is connected from the distribution box cable.
4. The rest are powered from this device.

Connection diagram for socket and switch: loop, series, parallel

Let's look at how to connect an outlet or a multi-unit unit. You can connect electrical outlets in parallel via a junction box or using terminals; this method is also called a daisy chain connection. When connecting electrical outlets with a cable, the cable is connected to the first unit of the block, and the cable for the next block is powered from the last. For a daisy chain connection, mandatory independent disconnections of the socket are required. To do this, the conductors are connected to the neutral conductors through terminals or soldering. Zero and phase are connected to the first electrical outlet. A clamp is placed on the grounding wire, from which a grounding wire is supplied to each of the units. To connect the second socket block, you need to connect the phase and working zero from the last unit of the first block, and the ground wire into the compressor.

Now let's look at connecting a conventional single-key switch. To do this, we connect the phase wire to the switch using a clamp marked with an English “L” or an “outward” arrow; we connect the zero to a clamp with an “inward” arrow or the letter “N”. We screw both wires securely. Since grounding is not used in switches, we cut off the excess wire and insulate it.

Another pressing question: “How to connect a switch from an outlet”? To do this, it is better to use a block consisting of an electrical outlet and one or more switches. A new cable is laid from the junction box. One core of the cable carries the phase to the switch, and the other leads the working “zero” to the socket. The remaining conductors pass to the lamps through switches. 3-wire wires (zero, ground and phase) are laid from the junction box to the lamps.

How to Install a Dual Indoor Grounding Receptacle

In many ways, the comfort of living in an apartment or house depends on the type and quantity of household appliances and electrical appliances installed in it. The lack of sockets is becoming a common phenomenon, causing the use of many extension cords and tees. These actions help solve the problem, but have side effects - wires get tangled under your feet, additional pads spoil the interior of the room. In some cases, a double socket will help solve the problem of a lack of connection points. Modern products are compact, sufficiently powerful and presentable in appearance. There is no need to invite specialists to carry out the re-equipment of electrical equipment. You can do the work yourself after familiarizing yourself with the safety precautions and the rules for selecting and installing electrical appliances.

Features of connecting the block

Modular sockets with a frame are built to power low-power devices. Sometimes a module reaches 6 units in one row. For aesthetics, they are combined with a special frame, which is matched to the color of the wallpaper, room, and furniture.

When installing, it is necessary to strictly observe the distances between individual blocks in the width of the dividing strip of the frame. Installation steps are similar to installing an additional outlet. Only the distances will be minimal and depend on the width of the cup holder and the size of the frame.

We connect the conductors in series to the terminals of each socket from the block.

When installing, try to avoid common mistakes:

1. The wire cross-section must be no less than that of the existing device.
2. The wire material must be the same to avoid corrosion. The WAGO terminal block with anti-corrosion lubricant allows connecting wires of different materials.
3. Violation of the order of connection of conductors. It is necessary to understand their purpose.
4. The connection is not strong enough. Electrical installation experience is required to determine the tightening balance.
5. It is unacceptable to lay the cable diagonally on the wall. It should only go from above.

The easiest way to “multiply” sockets is to install a double copy. This can be done quickly and conveniently.

Double socket in one socket

Since in most cases replacing single sockets is part of a minor repair, we will consider an example of how to connect a double socket using an old socket box or the space remaining after it, there will be no need to lay new wiring and restore the damaged interior. Although some cosmetic repairs may be required.

Removing the old socket

Before you start working with electrical wiring, you need to take care of your safety. First of all, turn off the power supply circuit breakers in the apartment panel. Then check that there is no voltage at the socket being replaced - use an indicator screwdriver for this.

If you do it yourself, the old socket is immediately dismantled. To do this, unscrew its mounting screws and remove the top cover. Next, the wires are disconnected and the fastening tabs of the product itself in the box are unscrewed.

The socket to be installed is disassembled in the same way: its front panel is carefully separated from the working part.

Installing a new socket box

I have a new Schneider Electric socket box pre-installed for indoor installation with a diameter of 68 mm. I have been using them for quite a long time, I can only say good things about them - very reliable and high quality.

In addition, on the front part there are mounting screws for fixing the socket support. If you have an old style electrical outlet or none at all, then it is better to install a new one. A normal socket box is the key to a securely fixed and non-falling socket.

In order for the socket itself to be securely fixed in the wall, it must be secured to alabaster or putty mixture.

Preparing to connect

Let's start cutting the cable. To remove the outer insulation, I use a knife with a heel from the STOCK. Some beginners may think that the more wire stock, the better (will be left for the future).

We don’t need long wires in the box, otherwise when installing the socket mechanism it simply won’t fit there. Therefore, we leave a wire reserve of approximately 10 - 12 cm.

If the wires from the old wiring are still short, you can try to extend them. By the way, there is a separate article on this topic on how to lengthen the wires in a socket.

Next, we strip the insulation from the conductive cores by about 10 mm.

Connecting wires

When the wires are prepared, we connect them to our contacts. According to the color marking, the wiring in the junction box is made in such a way that the phase wire is brown, the neutral wire is blue, and the ground wire is yellow-green.

Loosen the screws on the connection terminals, insert the wires into the contact and tighten the screws thoroughly using a screwdriver.

There is not much difference to which terminal to connect phase or neutral. It can be on the left, it can be on the right. I always connect the phase wire to the right contact of the socket. The main thing is not to connect them to one contact (bus), otherwise a short circuit will occur.

The ground wire is connected to the central contact located on the bracket. There is a "GROUND" icon next to this pin.

Installing a double socket in a socket box

When the wires are connected, you can begin laying the entire mechanism in the socket box. When installing a double socket in one socket box, it is important to carefully lay the wires in the box.

Do not allow them to get under the fastening tabs (otherwise the insulation will be damaged when they are tightened). Before installation, I bend the wires like an accordion and they fit perfectly.

Then the socket is carefully buried inside and fixed with self-tapping screws or fastening tabs that rest against the walls of the socket box. I'm using the first option.

Then, using a level, we set the socket’s level position in relation to the corners of the wall and the floor. Finally, its caliper is connected with self-tapping screws to the body of the installation box.

When the caliper frame is securely fastened, a decorative trim is installed. If the socket is installed correctly, it will lie flush against the wall, without a gap.

Connecting the socket and switch

When connecting a socket and switch, just look at their connection diagrams and everything will fall into place. You should also consider the wiring diagrams for sockets with single, double and triple switches.

Usually, the problem of a person who just wants to replace the switch-socket unit is that he sees only a bundle of wires, which does not give him the overall picture, and therefore prevents him from correctly orienting himself. It may also be that the previous installation was made with incorrect phasing, which also does not add clarity. So enough words, let's figure it out.

Connection diagram for a socket with a single-key switch

The switch is turned off (zero comes to its input through the light bulb)

The switch is on (through it the phase is supplied to the light bulb)

As we can see from the diagram for connecting a socket with a switch, we need three wires: one is where the phase comes in, the other is zero, and the third is where the phase returns through a jumper to the input of the switch, powering the lamp bulb.

It should be noted that the first three pictures (top) are with the correct connection, that is, zero from the junction box goes directly to the lamp.

Then in the connection box for the socket and switch we see three wires. Two, on which there is a zero (we get one zero through the connected lamp), and the other with a phase. This is provided that a working lamp is connected.

When replacing a block, we can (after de-energizing the line) simply repeat the connection (by adding a similar block or socket with a switch). But, if this is not possible, we need to determine exactly where which wire is. To do this, having de-energized the line, we make a braid.

Photo of a three-wire braid.

It will help us avoid shorting the wires and will give us the opportunity, if necessary, to place the wires in the sequence we need.

Then we turn on the line and use the indicator to find the phase, through it (the phase) we determine the direct zero with a control light (the control light glows at full intensity), the zero and the phase are connected to the socket, the other wire through the switch (the phase is supplied by a jumper to the switch input) should power the lamp.

When you touch it (the remaining wire), the control lamp glows at the incandescent level, and the lamp lights up weakly (if an incandescent lamp is connected) or lights up at full power (modern lamps).

Having decided on the wires, we de-energize the line and connect the socket-switch unit. Once assembled, turn it on and check its functionality.

Connection diagram for a socket with a single-key switch with incorrect phasing

Incorrect phasing is easily determined by the fact that the indicator will show two wires with a phase. All actions remain the same as described above with the only difference being that now the direct phase is located (searched for) through zero, and it (zero) is supplied to the switch input through a jumper.

You may come across a situation where there are not three, but four wires, do not be alarmed, it means that one wire is either not working, or a pair is taken by the core (two wires are simply connected together). Just insulate the wire you don't need and that's it.

Connection diagram for a socket with a two-button switch

The switch is turned off (zero comes to its input through the light bulbs)

The switch is on (through it the phase is supplied to the light bulbs)

As you can see, everything is the same, only one more wire has been added. Don't forget about the braid.

The circuit does not become much more complicated when connecting a socket and a three-key switch, but if you have understood the previous circuits, then this one will not be difficult for you.

In practice, here, too, there may be not five, but six wires, but this means that the electrician simply did not want to separate one wire from the double one and one wire is either not working, or the pair is taken by the core.

In two sockets

If there are two holes in the wall, in each of which wires are laid, the following solutions are available for this case:

1. Insert two devices into them with one socket each. You need to choose them so that the lids do not overlap one another or there is an opportunity to grind them off along the edges.
2. Purchase an internal socket with a long cover. Connect two holes into one. After this, you can plug the extra line and insert the mechanism in the middle of the created opening.

The choice depends on the residents' needs for electrical outlets. One option would be to install an outer horizontal block with 4-5 slots on top of the holes.

Embedding a socket box in concrete

The best way to secure socket boxes is to embed them in the hole using alabaster or rotband. A small life hack - so that the solution does not harden too quickly and you do not have to wait a day - you need to mix alabaster with rotband.

First, use a vacuum cleaner to remove all dust from the hole and moisten (prime) the hole with water. And only after this, we apply the solution with a small spatula, spreading it along the inner walls of the hole. The solution should be thick enough not to leak out of the wells

It is important to understand that the area of ​​contact between the solution and the socket box should be maximum! Plus, coat the socket boxes themselves with the mixture. The solution will envelop the socket box from all sides and adhere well to the base of the wall, only then can we say that the socket box is installed efficiently!

Using a large spatula, remove excess mortar while leveling the surface of the wall. Before this procedure, it is necessary to remove or screw in all the screws of the socket box.

Laying the cable in the socket box. It is best to lay the cable in an already installed socket box; the windows for the cable are easily knocked out with a screwdriver, and it is better to make channels for pulling the cable between the socket boxes in advance. When the solution has cooled, you can safely insert the cable into pre-made holes or recesses.

If you don’t have that much time and the cable needs to be installed together with the socket box, try to align the socket boxes as accurately as possible. You can insert the cable into any hole, but it is better not to use the side windows for this, so that there are no difficulties with the subsequent installation of sockets.

Open and closed wiring

The difference between the methods is noticeable to the naked eye. The closed wiring is located inside the wall, for which grooves (grooves) are punched or cut into it, in which the connecting wire is hidden under a layer of putty. Open wiring is laid along the surface of the wall, on which it is held in special fasteners or laid in plastic guides - cable channels.

Accordingly, if you can see the wires that fit into the outlet, then the wiring is of an open type. Otherwise, closed wiring is used, for the installation of which the walls were cut.

These two methods of connecting an outlet can be combined with each other - if the old points are connected in a closed way, then nothing prevents you from connecting a new one in an open way. There is only one choice - in wooden houses the socket can be connected exclusively in an open way, just like all other electrical wiring.

Open wiring - advantages and disadvantages

An analogy with the most common extension cord (surge protector), which is essentially an additional branch of the electrical network, but is connected not to a junction box, but to an outlet, will help you understand why open wiring is good.

• You don't have to cut the wall to install a new outlet. This is especially true for those premises that have already been renovated.
• Installation does not require tools such as a wall chaser or a hammer drill.
• In the event of a breakdown, you don’t have to open the wall - all the wiring is in front of your eyes.
• Installation speed. Even after all the work has been completed, adding another point to the existing wiring is a matter of several minutes.
• If desired, you can quickly completely change the wiring - ideal for temporary connection schemes.

• There is a high probability of external influence on the wiring - children, pets, you can simply accidentally hook it. This disadvantage is mitigated by laying wires in cable channels.
• Exposed wires spoil the entire interior of the room. True, it all depends on the design abilities of the owner of the room - cable channels will fit perfectly into modern design solutions, and if the room is made in a retro style, then special wires and other accessories are produced for this.
• The need to purchase special fasteners, even if cable ducts are not used - in wooden houses, open wiring should be laid at a distance of 0.5-1 cm from the wall surface. Wires are often laid inside iron pipes - all these requirements are aimed at increasing the safety of using open electrical wiring.

As a result, this connection method justifies itself if for some reason there is no point in laying the wires to the outlet inside the wall. Besides the fact that the wiring will be visible, there will be no differences in the operation of the outlet.

Hidden wiring - pros and cons

Despite some significant disadvantages, it is used almost everywhere - the advantages of its use still outweigh.

• The wires to the socket fit into the wall, so wallpaper or other finishing can be done freely on the outside.
• Meets all fire safety requirements (in concrete buildings) - even if a short circuit occurs, there is no fear of a fire from the wires in the wall.
• There is a very low probability of damage to the wiring - it can only be damaged when drilling walls.

• For installation you need to cut the walls.
• It is difficult to carry out repair work.
• If the walls are finished, then after installing an additional outlet you will have to redo it.

The disadvantages are leveled out by preliminary calculations - if you plan in advance where and which block of sockets should be installed, then problems usually do not arise in the future.

How to install it yourself?

Installation requires strict adherence to several steps:

1. markings;
2. drilling a recess for the socket box;
3. installation of the device;
4. assembly.

Wall marking

Attention It is necessary to use a building level (up to 1 m long) to align the device strictly vertically and horizontally. This guarantees easy connection

postpone

Drilling a hole

The deepening is done like this:

1. You need to hold the drill perpendicular to the wall, drill to the depth of the socket with a margin of approximately 0.5 cm.
2. Using a chisel and hammer, the middle part of the brickwork or concrete is removed.
3. When installing in a sheet of drywall, use the appropriate nozzle.
4. Drilling is performed similarly to concrete or brick surfaces, but the excess remains inside the crown. If there is no such tool, then a hole is cut in the plasterboard using a stationery or shoe knife.

Fixing a socket box in a concrete wall

1. A box is inserted into the brickwork or concrete and fixed to alabaster or mortar.
2. When mounting in a plasterboard sheet, you need to insert a socket box into the hole, and then tighten the screws that hold the sliding legs. It is necessary to tighten it with such strength that the fabric does not crumble and the device does not wobble.

Important Before installing the box in a niche, you must cut a hole in it for the wiring that will be connected to the terminals of the socket core

• If it is alabaster, then it will take about 2-3 hours for the solution to harden.
• If there is a different type of mixture, drying will take longer.

Connection diagram

First determine the exact location and orientation of the triple socket block

1. To fix triple sockets in the kitchen, you need to choose a place where several household appliances will be located - usually above the countertop, so as not to use tees or extension cords.
2. If the installation is carried out in a room, install it closer to the TV or computer - so that the screen masks the structure.
3. When installing in a kitchen or bathroom, where there will be high humidity and microclimate fluctuations, it must be mounted no closer than 0.6 m from the water source and no lower than 0.5 m from the floor. This will ensure the safety of the devices.

How to connect several outlets in a row

Connecting several sockets to one cable is called a “daisy chain” connection. This connection involves connecting several elements of one group (in our case, sockets) into one block. It is worth considering that connecting sockets with a “daisy chain” is suitable for powering electrical appliances and low-power equipment. This type of connection allows you to connect two or more outlets.

According to the location of the power cable, we drill niches in the wall for socket boxes and first level them. After installing the socket boxes, prepare the connecting jumpers (use a cable of the same cross-section as the supply cable). We connect the phase and neutral wires to the terminals of the first socket, as well as similar wires of the “loop” going to the next socket.

It is important to know! When connecting sockets with a “loop,” it is unacceptable to violate the integrity of the ground loop. The connection is made not with a “loop,” but with a separate wire for each outlet.

We fix the connected bases of the sockets in the socket boxes and install the front part, separately for each socket, and in the form of one frame for the entire block.

Preparing to connect the outlet.

To connect the outlet to the electrical network yourself, you need to prepare the following:

• decide on the type of outlet and purchase it;
• lay a wire to the location of the future electrical connector;
• prepare the tools necessary for installation work;
• follow the step-by-step instructions described below.

Today, stores offer a wide selection of different sockets for any room, in various designs:

• external;
• internal;
• single, double, triple, etc.;

There are no big differences when connecting one type of outlet or another. The only difference is in the way they are installed.

Fig.2 - design of sockets

Socket boxes are boxes made of plastic or material that is non-conductive and resistant to fire. To install it, you need a niche in the wall.

The socket box must be secured very firmly so that the socket along with it does not fall out of the installation location. This rule must be taken into account, because Many people do not turn off appliances from the network by holding the plug, but pull it out of the outlet by the cord.

When you can’t, but really want to

There are quite a few ways to install a grounded outlet, bypassing the provisions of the PUE. All of them are, to a greater or lesser extent, a violation - to use them or not - this decision is made at your own peril and risk, but in any case you need to be aware of the possible consequences. The fact is that many of these methods are used happily ever after, but sooner or later something happens that is why they were banned. As a result, neglect of electrical safety rules endangers the life or health of not only the owner of such wiring, but also other people living with him in the same house.

Zeroing

This is one of the most common ways to ground an outlet if there is no separate PEN conductor. To make a grounding, you need to connect the working zero to the grounding contact - this is done by installing a jumper in the socket itself. The connection diagram for this method of “protection” is based on the fact that even in old wiring, the working neutral conductor is grounded in the distribution transformer. After short-circuiting the zero and grounding, if a phase appears on the device body, a short circuit will occur and the input circuit breaker will turn off the electricity.

1. When a phase “breaks through” the housing, the device, although not for long, is still energized and if at that moment a person touches it, he will receive an electric shock.
2. If on the way to the socket the neutral wire in the wiring burns out (a fairly common fault in electrical wiring), then in most cases there will be a phase on the body of the devices. To do this, a single light bulb or power supply of any device that is not turned off is enough. In this case, the circuit breaker does not operate.

Connection to a lightning rod

If there is a lightning rod installed on the roof of the house, and the metal strip that connects it to the grounding passes close to the apartment window, then in this case you can connect to the grounding loop and conduct grounding to all sockets.

An excellent way to solve the problem, as a result of which the apartment will be connected to high-quality grounding. This method has only one drawback - grounding works well until the lightning rod is used for its intended purpose, or more precisely, until lightning strikes it. It is better not to know and not experience from personal experience what voltage will appear on the housings of devices connected to ground.

Grounding through heating pipes or water supply

Another common way to ground an outlet yourself is to strip a piece of water pipe and connect a grounding wire to it. On the one hand, it would seem a logical solution - the pipes in any case have contact with the ground. On the other hand, it is unknown to what extent this contact meets the grounding requirements, and if voltage appears on them, then there is a possibility that the current will not go into the ground, but will hit the person who is holding onto the pipe (washing his face or drawing water from the tap).

An additional disadvantage of this solution is the plastic water supply, which is often laid instead of rusted iron pipes. If the pipes on the fifth floor are metal, and on the third floor they are already plastic, then instead of grounding the pipes will simply be energized.

Connection diagram for two-button switch

Before starting installation, be sure to turn off the voltage at the distribution board and make sure that there is no voltage on all wires.

Two wires come into the distribution box from the electrical panel - phase (red) and neutral (blue).

The connection diagram for a two-key switch is assembled in the following sequence: the neutral wires from the electrical panel, lamp No. 1 and lamp No. 2 are immediately connected to each other. The phase wire that came from the electrical panel is connected to the wire that goes to the common contact of the two-key switch.

Two wires have already come from the switch, blue and yellow. The blue wire from the two-key switch is the phase wire for lamp No. 1, the yellow wire is the phase wire for lamp No. 2. One of them is connected to the phase wire of one lamp, the other to another.

In our case, the wire going to the common contact is brown, and the wires from the two outputs are blue and yellow.

In the junction box, these wires are connected to two corresponding groups of light bulbs or fixtures. Thus, these two wires represent the switched phases of two groups of electrical appliances.

The neutral wire that goes directly to the lamps is connected to the neutral wire (blue) of the distribution board in the distribution box. The switch switches only the phases of two different groups of electrical appliances.

After all connections, before soldering and insulating the twist in the junction box, we must check the correctness of the connections.

Why is a “phase” connected to the breaker break?

Let us remind you once again that the switch must break a phase, not a zero. This is done so that if repair work is necessary, for example, replacing a light bulb, you can safely work with the switch turned off, but without turning off the circuit breaker in the distribution board.

Let's say we need to replace a burnt-out light bulb in a room. We turn off the switch, take an aluminum stepladder, and place it on the damp floor. Having climbed this stepladder to the ceiling, we take hold of the metal part of the lamp socket, on which the phase. An electric current will pierce your body, since a metal stepladder and a wet floor are excellent conductors.

The consequences of electric shock and falling from a height can be unpredictable. Therefore, when installing electrical wiring, you should clearly understand what can happen if you do something wrong.

Similar materials on the site:

Connection materials

The wire for connecting the electrical point must be made of the same metal as the main cable. For example, when using an aluminum cable, the jumper must also be made of aluminum.

To ensure an even distribution of incoming electricity, the cable used for connection must have the same cross-section as the main wiring in the room

To install a double socket you also need:

• flat and Phillips screwdrivers;
• braid stripping tool;
• pliers;
• insulating tape.

For safety reasons in case of fire, it is recommended that any electrical wires be laid in corrugation. This solution is also convenient because it does not require breaking through the wall, and also simplifies the replacement of damaged wires during subsequent operation.

Main varieties

grounding

• C5 – standard, for Soviet-style plugs and without a ground wire. They are less common on sale, but can often be found in apartments where renovations were last done at least two decades ago.
• C6 are more modern, contain different types of grounding, and are equipped with wider holes for the plug pins. Available in a very wide range with the ability to choose a suitable design.

Depending on the modification of the outlet, the following categories are distinguished:

1. with a circuit breaker that trips in response to overloads;
2. without grounding or with it;
3. overhead or built-in;
4. external (external) with a protective cover;
5. internal, designed specifically for connection when organizing hidden wiring.

Advice Triple sockets with a common socket are more compact, easier to install, but less safe and convenient to use.

Security and Tools

1. Laying the cable and installing the power point is carried out after the machine or plugs are completely turned off. Using the indicator, make sure that the device is de-energized. It is better to use two indicators at once to guarantee verification results and to avoid undesirable consequences.
2. The condition of the distribution box to which the source socket is connected and the power point itself are taken into account. Damaged copies are not used for work.
3. The wall where the wiring is already installed is not chiseled, drilled, or cut.
4. It is forbidden to cut live wires with wire cutters.
5. Any contact between the screwdriver and the phase or neutral cable leads to a short circuit in the network.
6. Sockets are installed at a height of 0.5-1 m from the floor, but not lower than 30 cm from the baseboard, placing one point for every 6-10 square meters of the room.
7. Calculate the power of connected devices by adding them together. The result is compared with the total network throughput.

Attention: Do-it-yourself installation of wiring and a network socket is carried out provided that the installation and configuration of the distribution panel in the house or apartment was carried out by a professional. Connection without special education is dangerous to life

To add an outlet you will need

• marker;
• ruler;
• level;
• pliers;
• screwdrivers, one of which has a current indicator.

• container for construction mixture;
• primer.

Step-by-step instructions for replacing a regular electrical outlet with a double one

1.

First of all,

turn off the electricity supply

. Turn off the switch (or unscrew the plugs) on the electrical panel in the apartment or on the staircase.

Make sure there is no phase voltage in the socket. To do this, take an indicator screwdriver and touch its metal tip to the metal contacts of the socket one by one.

Your finger must be pressed against the metal contact on the indicator body, otherwise it will not work. If the light does not light (provided that the indicator is working!), you can start working.

2.

Using a screwdriver, unscrew the screw on the protective decorative cover of the old outlet and remove the cover.

3.

Unscrew (loosen) the two screws of the spacer legs by 3-5 turns.

If the socket is screwed to the socket box, then unscrew the screws holding the socket in the socket box.

Remove the socket from the socket box, carefully pulling out and straightening the electrical wires.

4.

Remove the screws that secure the wires to the outlet and disconnect the outlet.

5.

Take the new double socket, unscrew and remove the decorative cover from it.

If you had a grounded outlet installed, then install a double outlet also with grounding. If the socket that was installed did not have a grounding wire, then buy a double one without a grounding wire.

Screw the 2-color (yellow-green) wire to the ground terminal, connect the remaining 2 solid wires (usually white and blue) to the socket terminals using a screwdriver.

In the event that you have installed a socket without grounding, and there are only 2 wires in the socket box, you will need a double socket without grounding. Screw both wires to the power contacts of the socket.

6.

Install the socket into the socket box, carefully laying the wire in the socket box so that it does not fall under the spacer tabs securing the socket. Align the socket and secure it in the socket box using spacer tabs (which rest against the walls of the socket box) or, even better and more securely, using mounting screws. Replace the protective decorative cover of the outlet.

7.

Turn on the voltage and check the functionality of the outlet using any electrical device.

That's it, your new double socket is installed in place of the regular single socket and is ready for use. If, in the process of replacing the socket, you need to replace the socket box, you can also do this yourself after

As they say, nothing lasts forever and even the best quality things fail. Everything breaks down, wears out, fails, goes out of fashion, or simply loses its relevance. Sockets and electrical networks are no exception. Many residential buildings built during the Soviet era have worn-out electrical wiring and loose sockets. There is often a temptation to improve the situation during repairs, so that both the quality and appearance correspond to the modern style, and simply because sockets often fail without surviving a short circuit.

The location of the socket on the wall has also undergone changes. If previously they were usually located at a height of about 1 m above the floor, now it is fashionable to place them at a level of 40 cm from the floor level.

When the question arises of how to change an outlet, several options for solving the problem immediately appear in your head. Of course, without the necessary experience, there is only one way to correct the situation - calling an electrician or an all-knowing neighbor. But since this trouble is an everyday matter, it makes sense to delve into the basics of the principles of electricity and figure out the task at hand.

Installation of the socket block

Internal sockets can be single or double.
But if you need to place an internal socket with three or more sockets in one place, then you need to use an outlet block. The socket block is a special single sockets that are combined into a single structure by a common frame.

A separate socket box is installed for each socket of the block. The power cable is connected to only one socket in the block, and the rest are powered by jumpers.

Socket block connection diagram

Below is a photo of socket boxes in drywall for installing a block of sockets. In adjacent socket boxes, remove adjacent plugs for cable routing:

The photo below shows an example of a Sedna socket for a socket block:

And this is what the frame for a socket block with four sockets looks like:

As mentioned above, to connect the sockets in the block, jumpers from the cable cores are used:

Jumpers - phase, neutral and grounding for connecting sockets in the block

Connection points for the cable cores in the socket:

An example of connecting sockets in a block. The power cable goes to the first socket, and the 2nd, 3rd and 4th are connected by jumpers:

All sockets are installed and connected:

Installation of the front panels of sockets and the frame is completed:

Fixing in the wall

It is important to securely secure the socket box in the wall hole to prevent the socket from being pulled out during operation. For this, it is best to use alabaster, which you can buy in the store.

Dilute it with water to form a thick paste, then spread the mixture into the socket hole. After this, insert the socket box into the wall on the alabaster and be sure to level it. For the mixture to dry, you need to wait an hour and a half and only then install the socket. It is attached to the socket box with claws and screws - the socket is inserted and the fastening bolts are tightened. The final stage is the installation of the decorative panel.
