Plug-in socket of non-recessed type with open wiring according to the electrical diagram

Before you begin selection and installation, you need to learn what a three-pole socket is. This is a fairly simple device that has several distinctive characteristics compared to other types. Plug sockets consist of 3 main elements:

The plug socket is manufactured in various types.

They all differ from each other and are classified according to certain parameters. This allows consumers to narrow their search for the desired model and purchase the most suitable option for them.

According to the electrical circuit used

This parameter is considered one of the main ones and divides all sockets into 2 types. Both provide a safe and reliable electrical connection.

1. Three-pole. These sockets are used only in cases where it is possible to connect to grounding. It is connected using a separate contact. The holes for the plug pins are located slightly lower than for the grounding pin. Thanks to this, three-pole devices are ideal for connecting electric stoves, air conditioners and other household appliances.
2. No grounding. Unlike three-pole ones, they have only 2 contacts and are intended for the corresponding electrical wiring. However, it should not have a special grounding contact. Sockets without grounding are installed in old buildings where the old wiring has never been replaced with new ones. These devices are much cheaper than three-pole ones, but do not provide the opportunity to further protect yourself and the equipment you use.

Depending on the type of structure

According to this characteristic, two types of sockets are also distinguished. They are used for various methods of conducting electrical cables (external and hidden).

According to the degree of protection against moisture

All devices that are used to connect to electric current must be protected from moisture. Otherwise, there is a high probability of a short circuit.

Based on moisture resistance, sockets are divided into the following categories:

Self-installation

Installing three-pole plug sockets is quite simple, but requires a certain amount of time. You can do the work yourself only if you have the necessary knowledge and experience.

If you are not 100% sure of the success of the process, then it is better to contact a qualified specialist. This will not only help to install the structure efficiently, but will also reduce the likelihood of serious injury.

External method

This is the easiest installation method that you can easily do yourself. For successful completion, you must strictly follow the sequence of actions and not skip a single step.

Recessed option

This installation method is much more difficult, as it requires a lot of time and effort. During work, it is important not only to connect the structure correctly, but also to properly hide it in the wall.

The installation process consists of the following steps:

Option 1 – On the wall

The most popular and usual place for placing an outlet of any type is a wall. To correctly remove power from an electrical appliance or household appliance, the following steps should be taken:

• Determine the location for the future outlet, draw its outline on the wall.
• If there is no wiring near the selected location, then it is necessary to supply electricity: find the nearest distribution box and a suitable machine, identify the phase wire, cut a channel from the panel to the designated location, lay the wire.
• De-energize all rooms by turning off the panel or unscrewing the plugs.
• Make a neat hole in the wall of the required size using a drill with an attachment, drill bit, chisel and hammer.
• Install the socket box and secure it with plaster, cement or plaster.
• After the solution has cooled, it is necessary to level the surface and sand it.
• Pull the wires out through special holes in the box.
• Strip the phases of the conductors a few centimeters, connect the contacts of the socket and the shield.
• Seal the groove with plaster.
• Secure the decorative part to the box with special “claws”, latches, screws or screws.
• Check the functionality of the device.
• If necessary, equip with additional elements: protection, cover.

Plug socket of open and closed types

> Switches and sockets > Plug socket of open and closed types

The plug socket is part of the connector for quickly connecting electricity consumers. The design includes a housing, a plastic or ceramic base, spring contacts and terminals for connecting power. Models have a wide variety of designs.

A necessary accessory that forms a detachable connection with the socket through spring contacts is a plug with metal pins.

Socket device

According to the requirements of the PUE, the apartment needs a separate grounding circuit. On the plug of the connected device there is a third ground contact connected to the housing. It is spring-loaded and additionally keeps the plug from falling out of the socket. All elements are connected using screws.

The figure shows the socket with protective curtains covering the contacts. When the plug is inserted into the housing holes, they move away, providing access to the current-carrying parts. To make the curtains wear out less, they are reinforced with metal rings or strips. There are designs in which the curtains are moved back manually by turning the plate covering the socket.

Materials

The block used to be made of ceramic, but now it is more often made of thermoplastic or special polycarbonate. The plastic base is less fragile and cheaper to manufacture. The material has high performance parameters, but is inferior in quality to ceramics, deforming from heat and having a lower breakdown voltage.

Contacts are made of bronze, brass or copper plates. The alloy must be resilient to ensure a secure connection with the pins of the plug.

Classification

Sockets are made with different types of subsequent installation and number of connectors.

The socket is two-pole with protective contact. Review of recessed and non-recessed type plug sockets It is worth remembering that reliable and high-quality products will not only increase their service life, but also increase the guarantee of the safety of your home from fire and from electric shock. Ask, I'm in touch!

Classification of sockets

The device is usually classified according to a number of different parameters. About each in more detail.

Design characteristics

Depending on the type of construction, the device is divided into two types:

• Outdoor installation. Used when laying open electrical wiring. The main part is placed in a housing made of plastic. A non-recessed socket with open wiring is installed using a socket box. Often this design is additionally equipped with a protective cover and lighting.
• Concealed or recessed type. A flat plug socket is used for hidden wiring. The main parts - the block and the contacts connected to it - are immersed in the wall. The case is a mounting box, due to which there is practically no protrusion beyond the wall.

Which variety is best to install depends on the preferences of the household.

According to the electrical diagram

Three-pole socket
According to this parameter, there are also two types of devices:

• No grounding. Equipped with two contacts. Designed for two-pole wiring.
• Three-pole. Installed in the presence of grounding, connected to each other by a separate additional contact. Most often, this type is installed under electric stoves and air conditioners.

If you have difficulties choosing sockets, you can seek advice from an employee of the management company or a consultant at a hardware store.

According to the level of protection against moisture

According to this criterion, devices are:

• Regular or semi-hermetic. Designed for rooms where there is no risk of moisture. A few small drops do not cause malfunction. The exact markings are on the plug.
• Waterproof or sealed sockets. Designed for installation in rooms with high humidity levels. The housing becomes airtight thanks to a special membrane. Mounted externally.

It is recommended to give preference to sealed sockets when installing them in a bathroom or toilet room, or outside a private house.

By number of pads

This parameter also divides the electrical device into two types:

• Doubles are equipped with 4 connectors at once, which allows you to simultaneously connect two electrical appliances.
• Single or single-pole sockets are used to connect just one electrical device.

Having studied all the varieties and their features, you can begin purchasing and installing devices.

type of instalation

The open type socket is attached to the wall. These varieties most often have various additional decorative and functional elements.

Plug sockets are installed in most rooms; without them, it is impossible to turn on electrical appliances. The design of the device includes three main elements:

The last detail performs two important functions - protective and decorative. The building can be either single or double. The main part of the device is the block. The cover and contacts are attached to this element. It is usually made of carbolite or ceramics.

Sockets made of carbolite are considered more durable. But a block made of this material is found only in old-style devices. Ceramic products have one significant drawback: they are very fragile, so the device must be installed with great care, since a damaged part cannot be repaired.

Another working element of the socket is the contact, which serves as a conductor of electricity. They are made from metal alloys that have a certain degree of elasticity.

Types of hidden installation devices

There are several types of hidden devices. Depending on the method of protecting devices from water ingress, they are divided into:

• Standard devices and connectors. You can choose this option if the room does not have high humidity;
• Waterproof devices. Such sockets and switches can be installed in the bathroom, sauna or kitchen. Thanks to the moisture-resistant rubber elements, there is no risk of moisture getting in. In addition, you can choose special curtains and covers made of plastic. This will not only further protect the outlet from moisture, but will also help protect the child from unwanted consequences.

Depending on the type of electrical circuit, the socket can be:

• Grounded. Such connectors are equipped with a special part, which ensures the grounding of the outlet. Without going into details, this option is appropriate for the future connection of a stove, refrigerator or air conditioner. But you should understand that to install a grounded outlet, it is important that there is a grounding wire in the room;
• No grounding. I advise you to immediately install a hidden outlet with grounding, but if this is not possible, then you will have to use this option. Such models of sockets are called two-pin.

Depending on the number of sockets, hidden sockets can be:

• Single (having one single nest);
• Double (this and the next option are most often located in the kitchen, since this room requires connecting several appliances to the mains at the same time);
• Triple.

Switches and sockets for hidden installation are also divided into:

• Located in the wall (the most common use of this type of device);
• Recessed into furniture (in my opinion, an extremely good option, as it not only makes it easier to use the devices, but also gives the design of the room an original look).

Receptacle with ground contact for exposed wiring

A socket for open (external) wiring, it is also called “overhead”. It is mounted directly on top of the wall. This type of installation is quick and simple, but not entirely aesthetically pleasing in everyday life (apartment, cottage, office and other similar places).

This type of installation is relevant for industrial premises, outside buildings, in outbuildings and other typical places. Electrical wiring to overhead sockets is laid in a special corrugation or cable tray.

Features of installation of hidden installation devices

First, let's look at the method of installing a hidden socket:

1. Turn off the power supply.
2. Create a hole for the socket. Depending on the material of the wall or furniture, you may need a drill, electric drill, or hammer.
3. Install a special box in the hole in which the housing and wires will be located.
4. For high-quality fastening of the socket box, use plaster, glue or plaster. Lubricate all gaps with the selected solution.
5. Strip the ends of two or three cable cores and connect the contacts of the socket block to the power cable. First of all, connect the neutral wires, then the phase wires and, if available, grounding.
6. Attach the blocks to the socket box. This can be done using ordinary screws.
7. Install the housing and check the functionality of the socket.

Now let’s figure out how to install the hidden switch; to do this, perform the following manipulations:

1. Place the socket box into the pre-prepared hole.
2. Disassemble the switch into parts (core and cover).
3. Secure the wires using special clamps and tighten the fixing screw securely.
4. Tighten all other parts of the switch. Try not to move your body from the desired position at this moment.
5. Unscrew the spacers or tabs, and then insert them into the socket box.
6. Secure all support screws and be sure to check that the structure is stable.
7. Secure the protective frame.
8. Insert the keys, carefully aligning the special buttons and notches of the parts.

In conclusion, we can conclude that hidden switches and sockets have many advantages over their conventional counterparts. In addition, you now have a better understanding of the types of such devices and can easily select the product you need. And finally, based on the instructions in the article, you can quickly and efficiently install them. The main thing to remember is that the more carefully and responsibly you approach the hidden installation, the longer these electrical assistants will delight you and your guests.

Socket with grounding for hidden wiring IP44

Purely aesthetically, plug sockets for hidden wiring, after mounting them on the wall, look much more impressive than overhead ones, and the wiring is not visible.

From the point of view of electrical and fire safety, this method of installing sockets and laying wires is the most optimal.

If we compare the installation of the open type and the hidden type, then the hidden type is more labor-intensive, since the time and physical costs increase.

Basically, for installation in residential premises, sockets with a protection level of IP44 are used, but of course others are also possible.

Advantages of hidden installation devices

Speaking about the advantages of hidden installation devices, we should first of all note the aesthetic component. Sockets and switches recessed into the wall stand out from the overall picture only with frames and panels. In addition to the most obvious advantage in hidden devices, the following advantages can be highlighted:

• Flat devices do not collect a lot of dust on their surface;
• Furniture located in the room can be moved freely without fear of catching the protruding parts of the devices;
• Among other things, the shapes, textures and materials of such devices are very diverse, which means you can choose all the details to suit the specific design of the room.

Installation standards and requirements

When installing sockets that perform the function of supplying current to electrical appliances, you must not only follow a clear algorithm, but also adhere to certain standards and technical requirements.

1. In premises, you must follow the calculation - 1 socket for every 6 m² (in corridors of 10 m²).
2. When installing sockets in the kitchen, you must adhere to the following standards:
3. for 8 m² you will need at least 3 sockets of 6 A and one with grounding of 10 or 16 A, through which devices with a power of up to 2.2 or 2.5 kW will be connected;
4. in kitchens with a surface area of ​​more than 8 m², 4 6 A sockets will be required;
5. If it is necessary to install stationary stoves, sockets rated for 25 A will be required, and grounding is required.

1. IP20 models are suitable for living rooms, IP44 for bathrooms (the first number indicates the diameter of objects that will not damage the housing, the second determines the degree of moisture protection).

To understand labels well, you need to focus on the following numbers and indicators:

• 0—no protection;
• 1 - withstands touch from the back of the hand;
• 2 — protection against contact with fingers;
• 3 - provides protection against access by hand tools;
• 4 - protective level against penetration of small nuts, individual conductors and bolts;
• 5 or 6 - full level of protection against mechanical impact and unwanted contact with excellent dust resistance.

The level of moisture protection is marked as follows:

• 0 - no protection;
• 1 - drops (vertical) may get on the body;
• 2 - drops falling at an angle of 150° are not dangerous;
• 3 — the socket is protected from rain;
• 4 — protection against splashes in any direction is provided;
• 5 - no danger from water jets (maximum degree of protection).

Plug sockets marked IP20 are suitable for living rooms, and IP44 for bathrooms.

Plug sockets are an incredibly convenient device at home and at work, which is clear and easy to use. But few people think about how the outlet works and whether it is easy to install it yourself.

With the right approach, you can quickly understand this process and then carry out independent installation. This will not only allow you to be proud of yourself, but also save a certain amount of money.

A plug socket is a contact device for connecting various consumers to the power supply network. They can be any devices and devices that use alternating current of industrial frequency for operation, both for domestic use - televisions, toasters, refrigerators, etc., and specialized or industrial - welding machines and other similar equipment.

Electrical plug sockets are usually used in single-phase alternating current networks with a voltage of 220 V and a frequency of 50 Hz. They are connected to two- or three-pin plugs, often called plugs in everyday life. The form of contacts adopted in Russia and most European countries is round, in the countries of the American continent and some European countries it is rectangular. One contact is phase, the second is zero, and for individual sockets there is a third contact - ground.

The main classification of electrical outlets is based on the method of their installation. First of all, they are divided into internal and external - overhead sockets.
