How to install a double socket with your own hands - step-by-step instructions

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 double sockets

Also, 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.

Construction device

In every apartment and country house, inconspicuous devices are installed that ensure the operation of a TV, electric kettle, washing machine, refrigerator and many other electrical appliances that are so necessary for people’s comfortable living. To avoid mistakes when choosing, you need to understand the characteristics of the products.

The main elements of the product are:

• frame;
• built-in fittings;
• cable for connecting the fittings to the power source.

The potential difference between the internal contacts contributes to the creation of voltage, which is the power source for absolutely all electrical appliances. Voltage is transmitted through special holes.

The structure of the fittings is as follows:

1. The base is made of ceramic or plastic. Contacts are secured using metal plates.
2. An additional function of the plates is as a place for screw fastening of cables.
3. Popular models with a grounding function are available. They are equipped with an additional contact or plate.
4. The structure is installed in a glass or attached to the back cover with rails. Depends on the type of installation.

An upper decorative overlay is required. It is screwed to the base using screws. Models with snap-on clip are available. Only in this form can the product be used safely.

Installing a double socket in one socket box

A double socket consists of two plugs, but is installed in one socket. Using certain tools, it is not difficult to install the product yourself; you just need to follow some rules.

Dual Socket Installation Tools

Set of tools required to connect a two-socket socket:

• a screwdriver comparable in size to the screws of the structure;
• a screwdriver coated with a dielectric;
• cable (not required when replacing the product);
• perforator;
• socket;
• knife;
• self-tapping screws;
• wire cutters;
• multimeter

What do you need to know before connecting a double outlet?

Before proceeding with the installation of the structure, it is necessary to carry out some preliminary measures:

• choosing a location for an outlet;
• cabling;
• installation of a socket box;
• selecting a specific type of outlet.

It will be problematic to install the device yourself without an idea of ​​what phase and zero are in electrics. This is the name given to the conductors of electricity in an outlet. Current is supplied through the phase electrical wire, while the zero current is used to protectively ground the structure. In new types of sockets, there is also a third cable - a protective neutral cable, which additionally protects the product and prevents short circuits.

Usually the phase is located on the right, but it is a good idea to check its position. To do this, use a special tester screwdriver or multimeter. Hands must be protected with rubber gloves. When testing, the screwdriver will indicate the location of the phase wire with a light signal. After taking measurements, the line must be de-energized.

In a room where grounding is provided, the outlet also has a grounding contact. “Ground” is connected only to the central terminal of the device.

Step-by-step process for installing a socket yourself

Removing the old structure

1. We de-energize the outlet by turning off all switches in the electrical panel. To make sure that there is no current in the outlet, use a multimeter - an electrical measuring device.
2. When starting to disassemble the old structure, the first thing you need to do is unscrew the screws and remove the upper part of the body. The device cover is made of plastic and is usually secured with two screws.
3. Under the cover there is an internal socket mechanism, with which further work is carried out.
4. The working part of the product is also removed by unscrewing the screws. In this case, you should carefully hold part of the old socket.
5. Using a knife, you need to expose the wires by 10 mm.
6. The new device also needs to be divided into 2 parts - the base and the cover.

Replacing the socket box

Sometimes it is necessary not only to install the structure, but also to replace the socket box at the point. The need to replace equipment may arise for a number of reasons: the electrical outlet has become cracked, broken, or it turns out that it did not perform its functions properly.

Types of socket boxes

Installing a new device will not cause any particular difficulties. After removing old equipment, a certain procedure must be followed:

1. You can remove the old device by unscrewing the screws that secure it to the wall.
2. To pull it out of the wall, you need to pry it with a knife (when installing a socket box in a plasterboard wall). If the room has concrete and brick walls, you can remove the mechanism using pliers or a screwdriver.
3. Wires are inserted into the new socket box. It is important before purchasing a new device to measure the diameter of the hole or the old design, since the dimensions of the socket boxes may vary.
4. To fix the device in the wall, use a gypsum solution, which is prepared according to the instructions included with the product.
5. After the solution has dried, you can begin installing the socket.

Installing a new outlet

When working with a double socket, actions are performed by connecting both structural elements to the same wiring line. 6 wires are fed into one of them, and a loop of 3 main wires into the second.

This means that one element of the socket will receive current and subsequently transmit it to another.

Connection diagram

Socket connection diagram

1. Before installing a new device, experts advise cutting the ends of the wires again. Using wire cutters, they need to be shortened by about a centimeter, and then the ends should be cleared of insulation.
2. If the wire is stranded, it must be twisted more tightly.
3. The inside of the new product must be carefully inserted into the socket box so that the socket fits evenly into the hole.
4. Pressing the part firmly against the wall, you need to tighten the screws and fix the device in the socket.

Connecting wires to the socket block

Please note that the wires are connected in a special way (as shown in the diagram below). Failure to follow instructions may result in a short circuit.

Connecting wires to the socket block

When installing the equipment, a neatly rolled wire is first placed in the socket box. It should not come into contact with the spacer legs of the box, otherwise the socket will not work properly.

Important! To ensure safety, the grounding wire must be unbroken, i.e. connect to the elements through a branch wire.

When installing a socket at a new point, it is recommended to check the length of the wire. It should not exceed 20 cm, otherwise it may not fit into the socket box.

When connecting a double socket from two single

Sometimes, instead of a paired product, a double version is used, that is, two single devices (separate electrical points) are combined into one socket box. In a double device, the sockets are connected to each other by jumpers.

One socket box has two single sockets

In this case, the wires will be connected in a different way, depending on the presence of grounding:

Connection diagram for two single sockets

When working with a socket mounted in this way, it is not recommended to use powerful electrical appliances.

Basic rules for wiring sockets

The rules for installing sockets and the tools that may be needed in the process are regulated by SNiP (building codes and regulations) and GOST.

When installing electrical wiring and working with sockets, you must familiarize yourself with the Electrical Installation Rules (RUE):

• wiring elements (distribution box, meter, sockets, switches) must be easily accessible;
• sockets are installed at a distance of 50-80 centimeters from the floor. The rule is taken for safety purposes when the premises are flooded;
• if there are gas or electric stoves in the room, as well as heating radiators and pipes, sockets are installed at a distance of 50 centimeters or more from grounded equipment;
• wires to devices are laid from bottom to top;
• sockets in the room are installed at a rate of no more than 1 per 6 square meters. You can connect more sockets only in the kitchen;
• equipment cannot be installed in the toilet;
• The wiring is laid at a distance of 10-15 centimeters from pipes, floor beams and ceilings. The height of the wiring from the floor should be 15-20 cm;
• wiring and connection of wires are carried out inside the distribution box;
• “Ground” and “Zero” are connected to the devices with a bolted connection.

This is all the information you may need when connecting a double socket yourself. Having mastered the necessary rules, anyone can connect a new device with their own hands. Experts recommend that beginners pay special attention to following safety rules, since they will have to work with contacts that conduct current.

You can once again familiarize yourself with the features of the double socket installation process by watching the video:

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.
