Plug sockets are an integral part of almost any electrical network today. Many people consider their main task to be the communication of an electrical device through a plug. They are considered quite common and that is why everyone should know what they are for and how to install them.

Design of sockets

In our article you will find detailed information about their design, as well as how to avoid violating the installation rules during installation.

Plug connection is... What is Plug connection?

Plug connection is a detachable device for quickly connecting and disconnecting electrical circuits.
The basis of Sh. s. They consist of electrical contacts (See Electrical contact) in the form of metal sockets and metal pins or plates (knives) inserted into them. Number of contacts in Sh. s. from one to several hundred (in the latter case, the sh. s. is often called a plug connector). The simplest Sh. s. — a plug and socket for connecting household and industrial portable appliances to the electrical network. Great Soviet Encyclopedia. - M.: Soviet Encyclopedia. 1969-1978.

Classification options

Plug devices are usually classified according to a number of parameters.

By type of design

Depending on the type of device design, there are two types of sockets:

Hidden installation. Such devices are used for internal network wiring (hidden wiring). The base of the device is in the form of a block and the contacts are immersed inside the wall. The housing is placed in an installation box, due to which there is practically no protrusion beyond the plane of the wall. Squeezing out wires due to a properly mounted (recessed) connection unit is impossible. Tight pressing of the fork is ensured by a washer (spring). One end of the fork will rest against the stop, and the other has a support in the form of a body.
Outdoor installation. It is used in case of open wiring and is attached directly to the wall. The base of the device is located in a plastic case. It is mounted in the wall using a socket box (non-recessed). Often this design is complemented by a protective cover and is often equipped with a backlight, has a plug ejector, or is equipped with a shutdown timer.

According to the electrical diagram

Based on this parameter, there are also two types of devices:

Three-pole. Required if there is grounding and are connected to it using a separate contact. Due to the fact that the sockets for the plug pins are located below the hole for the grounding pin, when power is applied, grounding is performed before it is applied, and removed later. These sockets are used to connect an air conditioner. Suitable for electric stoves.
No grounding. Two-pin, intended for two-pole electrical wiring without a grounding contact.

According to the level of moisture protection

Depending on this indicator, sockets are:

Waterproof. Designed for installation in rooms with high humidity levels (bath, sauna, bathroom). The property of protection against moisture is provided by a special membrane. It is often used as dense rubber rings, which are necessary as a reliable water barrier for contacts. Additionally, there is an internal flange on the curtains and plastic covers, which is responsible for removing accumulated drops of water and condensation. Typically, waterproof sockets are equipped with a remote housing. They are installed externally.
Regular. Suitable for installation in rooms where there is no humidity or there is no danger of water getting into the outlet. This category includes all types of sockets that do not have additional protection from moisture. But the ingress of drops is not always dangerous for them, so we can call them semi-hermetic. The exact markings of the sockets will be given below.

By number of pads

This parameter also divides all sockets into two types:

Single rooms. Designed to connect one electrical device to the electrical network (single-pole sockets).
Doubles. These devices have 4 connectors, allowing you to connect 2 household appliances to the mains at once.

PLUG CONNECTION is... What is PLUG CONNECTION?

PLUG CONNECTION PLUG CONNECTION (plug) - used to connect portable electrical devices (lamps, heating devices, etc.) to the network. It consists of a plug socket with two sockets, fixedly mounted on the wall, and a plug with two contacts - rods inserted into the socket sockets. A portable device is connected to the plug via an electrical cord. Preference should be given to detachable plug sockets, inside of which a fuse is inserted (see Electrical fuse). If a device connected to such an outlet malfunctions, this fuse blows, and not the fuse on the distribution panel, and only the faulty section of the network is turned off. To replace this fuse, remove the cover from the socket outlet. Typically the plug stems are split at the ends. In apartments, plug sockets are installed for a current of up to 10 A. It is allowed to connect household appliances with a power of up to 1,250 W in a network with a voltage of 127 V and up to 2,200 W in a network with a voltage of 220 V to such an outlet. For information about installing a plug socket, see the article Electrical wiring. Concise encyclopedia of household management. - M.: Great Soviet Encyclopedia. Ed. A. F. Akhabadze, A. L. Grekulova. 1976.

Installation and connection of sockets with spring terminals using the example of ABB Basic 55

The Basik 55 series from the famous ABB brand is a line of internal plug sockets (for recessed installation) with grounding and plastic blocks. A distinctive feature of the series is spring rather than screw terminals, which facilitates installation and avoids overtightening or, conversely, too loose tightening of bolted connections.

Installing indoor outlets is a little more difficult and requires more precision than outdoor ones. List of main connection steps:

preparing the installation site;
installation of a socket box;
cable entry into the socket box;
cable cutting;
connecting conductors to terminals;
installation of pads with support;
checking the installation accuracy by level;
installation of a protective and decorative cover;
supplying current and checking functionality.

Please note: any plug sockets must be installed only in accordance with the PUE - Electrical Installation Rules. Not only the installation locations are regulated, but also the number of sockets per room, kitchen or bathroom, and the cross-section of the connected cable in accordance with the technical characteristics of the equipment and the purpose of the socket.

As a rule, sockets that can withstand 10–16 A are used for household power supply (see labeling). According to modern standards, wire of type VVG or VVGng with a cross section of 2.5 mm square should be used for them. You can also use a cable with a cross-section of 1.5 mm square, provided that energy-intensive equipment such as a heater (preferably nothing more powerful than a table lamp) will not be connected to the outlet, since a cable with a cross-section of 1.5 mm is intended mainly for lighting.

If you need to connect a powerful current consumer - an electric stove, boiler, welding machine, etc. - then the cross-section of the cable (each core) must be at least 4 mm, and the electrical outlet must be designed for 25 A.

Plug sockets are placed at a height of 30–80 cm from the floor level. According to modern standards, it is customary to place them low, with the exception of a children's room. They should be located no closer than 10 cm from gas pipes and the stove. Laying cables inside the wall - exclusively vertically or horizontally, or diagonally - is strictly prohibited (otherwise you can subsequently accidentally break the wire when driving a nail or drilling into the wall).

First, you need to prepare a niche for the socket box by pulling the old one out of its nest (along with the socket) or by drilling or gouging out a new niche. In a plaster wall this can be easily done with a hammer and chisel if you don’t have a special drill attachment.

Install a socket box in a niche, placing it on plaster or a mixture of gypsum and PVA terminals. It should not protrude beyond the wall. Carefully remove any excess plaster, wait until it dries and check that the socket box is flush with the wall. Enter the cable through the side socket. Cut the wire (MUST check that it is not live), stripping the ends by about 1 cm and removing the top sheath by 5-7 cm.

Then insert the bare ends into the terminals of the block until you hear a click.

Attention! ONLY the yellow-green ground wire is connected to the central terminal; blue and white (or wires of other colors) are connected to the outer ones!

Place the block with the connected wires into the socket box (it comes with a metal frame - support), so as not to crush or break the wires. Level the top or bottom edge of the frame. Secure the block using the sliding “legs” and screw the self-tapping screws into the corresponding sockets. Replace the faceplate. Installation is complete.

Installation in high-strength concrete with reinforcement

If the concrete turns out to be highly durable, you start drilling and realize that this will take a long time, you can make your work much easier.

To do this, make several holes along the circle you started with an 8mm drill. You should end up with something similar to a revolver drum.

After this, continue with diamond or impact drilling. From there it should go like clockwork.

If you hit a large piece of reinforcement and you don’t want to ruin the new crown, then you can get out of the situation in two ways:

switch the hammer drill to the chipper mode and knock it out with a chisel

True, this can greatly contribute to the appearance of new cracks in the plaster.

remove a good crown and put in an old used one, then, without sparing it, chew through a metal rod (do not throw away the old ones, they may still be useful)

Knock out the concrete from the niche (using a chisel and hammer or a hammer drill), while providing a bevel for inserting the cable into the socket box.

Use a vacuum cleaner to remove all debris and dust.

Plug connections for 12 - 36 V must be structurally different from plug connections for PO and 220 V. [16]

Plug connections for voltages of 12 and 36 V must differ in design and color from plug connections for voltages of 127 / 220 V. [17]

Plug connections for voltages of 12 and 36 V are different in design and color from plug connections for voltages of 127 / 220 V. [18]

Plug connections (sockets, plugs) used in networks with voltages of 12 and 36 V must differ in design from plug connections intended for networks with voltages of 127 and 220 V in order to exclude the possibility of erroneous connections. [19]

Plug connections for switching on portable electrical receivers should be used with a special contact for connecting the grounding wire both on the socket and on the plug. If the body of the socket is metal, it must be connected to a grounding contact. [21]

The plug connection for the lamp of the first design, 10 o, 250 V, splash-proof ShSS1 - 10 / 250 - B (Fig. 43 a) is an element of the lamp suspension. [23]

Plug connections intended for connecting power tools and hand-held electric lamps must have protected live parts and for voltages NO and 220 V have a grounded contact that, by design, excludes the inclusion of live plugs. [24]

Plug connections designed for voltages above 36 V must have contacts for forced and advanced switching on of the wire grounding the housing of the electric motor being switched on. In the event of a power outage during work or a break in work, the electric motors of devices and machines must be disconnected from the power supply. [25]

Plug connections intended for connecting electric heating devices, power tools and portable electric lamps over 36 V must have inaccessible current-carrying parts and an additional grounding contact for forced and advanced switching on of the wire grounding the housing. [26]

Plug connections (sockets, plugs) used for voltages of 12 and 36 V must differ in design and color from plug connections used for voltages of 127 and 220 V; the possibility of plugging 12 and 36 V plugs into 127 and 220 V plug sockets must be excluded. [27]

The plug connection in broadcasting equipment is carried out using switching plugs, sockets and cords. [29]

Plug connections for voltages up to 36 V inclusive must have design features that prevent the tool from being connected to a higher voltage network; in addition, these compounds must be painted in a special, unique color. [thirty]

Main types

Power sockets are divided according to the method of execution and purpose into the following types:

With built-in RCD - useful in fire hazardous areas.
Having a timer - according to its signal, they are independently disconnected or connected.
With a built-in ejector - this device is activated after pressing a certain button.
With protective curtains - there are plastic covers on the contact holes; to use the socket, they need to be moved with the pins of the plug.
A plug connector with grounding, that is, with grounding contacts or a specialized plug. Its design ensures initial contact with it, not with contacts.
Sockets without grounding are used to connect household devices that do not have a grounding contact.

In addition, there are differences in the period of use, protection from water and small particles, and the size of the inlet.

Rules for installing a socket box

The operating procedure is as follows:

Using a d-6mm drill (or the same as on the crown), drill the center of the niches of future socket boxes (71mm between the “holes” if we are talking about a block)

Drilling depth - 5cm.

Using the selected crown, drill out 5-10mm of concrete, after which the centering drill is pulled out from the crown

If you leave it, then when the hammer shakes during operation, the drill may become wedged and break off. In addition, when diamond drilling without impact, the drill will only smooth the concrete and interfere with the work.

finish drilling the concrete with a crown to the required depth (about 5 cm)

The depth can be set in advance by placing the box on the bit and marking the required drilling distance with a marker.

When drilling, you need to rock the hammer slightly from side to side. This is necessary so that the sludge comes out and the crown does not jam. In this case, you need to adapt, since strong swaying also leads to a wedge.

This action greatly influences both the speed of operation and the increase in the service life of the product.

Important to know before starting work

Safety conditions

It is important to do all work on installing sockets and switches, laying electrical communications only after a complete shutdown of the current in the network. Turn off the machine or traffic jams

And do not connect until the installation work is completed.

Take the indicator and make sure that the outlet or wiring you are going to work on is de-energized. Professionals suggest using two indicators at once. This will ensure that unwanted consequences are avoided.

Points to consider

You should monitor the condition of the wire insulation and do not use damaged wires.
It is strictly prohibited to cut live wires with wire cutters.
In places where wiring has already been laid, you cannot chisel, drill or cut walls.

Any contact of a screwdriver with the zero and phase wires inevitably provokes a short circuit in the network.

Socket installation standards:

not lower than 20 cm from the floor;
for every 6–10 sq. m. of living rooms, one socket is made.

Rules for installing sockets and switches

In order for the installed system to serve for a long time, it is important to choose the right wires and cables to be connected and lay them out correctly

To do this, you should take into account:

The power of all future energy-consuming appliances in an apartment or house. The performance of all devices is simply added together. It is necessary to know what the maximum power allocated by the network is.
The choice of wire or cable type depends on the method of laying it: open or internal. It is necessary to decide which gasket is suitable for a specific electrical installation location.
When laying wiring, do not lay the wires in bunches.
