Installing Socket Outlets Yourself

New trends in socket outlet installation

Modern appliances consume much more electricity than in Soviet times. Nobody even thought about such devices and their power consumption back then. According to all regulatory documents, when purchasing large household appliances, each device should have its own dedicated socket with independent connection to the electricity meter and installation of a residual current device (RCD), rather than just "plugging in" a new socket into an old, overloaded system.

For example, electrical safety rules and use of electrical appliances require separate sockets for washing machines (with grounding required!), electric stoves, and even a dedicated socket for refrigerators!

With independent connection of each socket to household appliances with high electricity consumption, it will be easy to identify the cause of a breakdown or power failure, and protect equipment from damage due to a fault in a specific part of the network.

Moreover, appliances powered by their own socket will not overload the apartment's electrical wiring, allowing simultaneous use of several powerful devices (e.g., a washing machine and an electric stove). Otherwise, high network load may trip circuit breakers.

If you live in an old apartment, seriously consider not just installing a couple of new sockets but replacing the entire electrical wiring.

During a major renovation, replacing the electrical wiring is just as important as leveling the floor or replacing windows.

One cannot do it alone without professional help: knowledge of how to calculate wire capacity, how to properly connect wiring to the electricity meter, which sockets to choose for specific appliances, and how to design a socket installation plan in an apartment is essential.

Installing Socket Outlets: Regulatory Documents

For doing the work yourself, gather these documents:

GOST 7397.0-89 (installation of switches);
GOST 7396.1-89 (installation of socket outlets);
GOST 8594-80 (boxes for installing switches and socket outlets);
SNiP 3.05.06-85 (technical requirements).

Rules for Installing Socket Outlets

Installation rules for socket outlets vary not only based on the electrical points designed to power specific household appliances but also depend on the type of room and the material from which the walls were made.

Installing Socket Outlets in the Kitchen: General Requirements

Socket outlets should be installed no higher than 10 cm above the floor level (measured from finished floor to top edge of socket outlet).

For built-in appliances, sockets can be installed behind cabinet panels located near the appliance. The installation height should not exceed 60 cm but also should not be lower than 30 cm above the finished floor level. This type of installation requires cutting an opening in the back panel of kitchen furniture for the socket.

The length of the connecting wire from the appliance to the socket should not exceed 150 cm.

Kitchen socket outlets may be installed inside a cabinet with a sink. The degree of water protection for such sockets should not be less than IP44 (this index indicates the socket's protection against water splashes).

A socket for an exhaust fan should be installed no lower than 50–60 cm from the top of the kitchen cabinet. The recommended distance between the exhaust fan and socket should be 20 cm.

IMPORTANT! The socket must not be blocked by the exhaust fan's ventilation duct.

Socket outlets for small household appliances should be installed on the cabinet front but not higher than 1–1.4 m from the floor level.

IMPORTANT! It is forbidden to install socket outlets:

above the stove;
behind the casing of built-in appliances;
behind sliding drawers;
above the sink.

Scheme 1 — Kitchen Socket Outlet Installation Scheme

Installing a Socket for a Razor: Main Requirements

The socket must be grounded. In older homes, grounding is not provided for every socket outlet, so to ensure the safe use of small household appliances (e.g., electric shavers in this case), a isolation transformer can be used.

Wiring must only be installed concealed.

Socket outlets should be placed on walls near heating nodes (condensation, formed on cold walls due to temperature differences, can damage the socket and its connected device).

According to PUE (Electrical Installation Rules), the socket should be at least 0.6 m away from a bathroom or sink.

In a bathroom, only waterproof socket outlets are allowed (these sockets have protective covers and special seals that prevent moisture from entering).

For places with high humidity (kitchen, bathroom), installing a socket with an IP44 rating is sufficient.

Manufacturers: For better reliability in operation, it's better to choose socket outlets from brands such as Kontakt, KORR, Gira, or ELSO.

Installing a Washing Machine and Other Powerful Household Appliances

To protect against electric shock and ensure safe operation, all large appliances must be connected to an RCD (Residual Current Device).

A washing machine should be connected to a three-pin socket with a three-core cable (neutral, phase, and ground).

IMPORTANT! It is forbidden to connect washing machines through an extension cord from other rooms!

A separate, RCD-protected circuit with a leakage current of 10 mA (according to PUE) should be organized for powering a washing machine.

Installing a socket in a bathroom is strictly forbidden!

An automatic switch recommended by the manufacturer of the washing machine must be installed.

Scheme 2 — Bathroom Zoneing: 0 – No electrical appliances may be placed, except those that can be used in the bathroom (up to 12 W); 1 – Only water heaters may be placed; zones 0, 1 and 2 are not intended for socket placement; 3 – Sockets with power supply from an isolation transformer are allowed

Installing a surface-mounted socket is better in terms of heat dissipation than concealed installation.

Manufacturers: For reliable operation, it's better to choose products from brands ABB, Legrand, or Prodax.

Installing a TV Socket

The essence of installing a socket for a television is to hide the antenna cable in the wall and run it to the location of the TV.

TV socket installation should be done away from the signal source – an antenna or splitter. The cable for the socket is best laid in a baseboard in a special cable channel. TV socket installation in an installed box should be done with at least 10 cm of extra cable. Otherwise, the installation of an antenna socket is similar to that.

For the same reasons, it is also advisable to install an RJ-45 network socket. The process of installing a network socket is similar. When connecting the network socket, it's important to insert the wires into the slots of the socket according to their color coding and crimp them by snapping the tabs.

Installing a Telephone Socket

Instructions for installing a telephone socket:

IMPORTANT! All work should be performed wearing protective gloves!

Remove insulation from telephone wires.

Open the socket cover.

Connect the phone cable to the appropriate wires of the socket (red wire – negative, green wire – positive).

Close the socket cover and secure it to the wall with screws.

Rules for Installing Socket Outlets Depending on Wall Material

In wooden houses, due to the increased flammability of wall materials, external socket outlets are more often used, meaning the socket is not embedded in the wall. A non-flammable base (textolite or phenolic) is placed under such a socket, and the socket boxes are screwed to the wall.

For installing internal sockets, a hole of the appropriate diameter is first created for placing socket base plates or socket boxes. The socket is then mounted on spring clips.

In any case, it is forbidden to run electrical wiring openly in wooden houses, and when concealed, cables should preferably be placed in flexible conduits or metal sleeves.

Installing socket outlets in a block means installing several sockets in sequence. The advantage of this method is its reliability: the block installation is less prone to loosening or play. The socket box or any other mounting base for block sockets must be selected exclusively from the set offered by the manufacturer, as blocks from different manufacturers may have a different mounting system. Manufacturers: In their class, the best product is from brands ANAM and VIKO.

To install socket outlets in concrete walls, grooves must be cut (with a grinder, perforator, or special tool – a groove cutter). Before laying the cable in the groove, it should be placed in a corrugated tube and secured to the wall with plaster. After installing the mounting box in the groove, the cable in the tube should extend from the box by at least 10 cm. The box is then secured to the wall (the same method can be used with plaster). In brick, a socket is installed the same way as in concrete.

In blockhouse construction, socket outlets should be installed before finishing the wall cladding: cable trunking is laid out, installation points are determined, and the mounting method is decided. Wiring should also be placed in grooves or voids under the blockhouse. Sockets are usually installed in the wall finishing material, cut into the chosen depth.

Socket outlet installation in gypsum board should be done using special accessories for electrical network installation (available in every construction store selling gypsum board). This primarily includes mounting boxes with slots and special clamping screws that easily enter the gypsum board and securely fasten in their designated sockets. Socket outlet installation in gypsum board is also done after assembling the panel frames and before installing the finishing panels: cable channels are laid out, socket locations are determined, etc.

IMPORTANT! Socket outlets in concrete, brick or GVL walls are secured with anchors or nails, while in wooden walls, they are installed with screws or nails.

Installing Socket Outlets and Switches

Installation standards for socket outlets and switches differ depending on the material of the walls.

The European standard specifies that socket outlets and switches should be installed no higher than half a meter above the finished floor level. However, placing elements at a height of 1.5 meters or more above the floor level, which is familiar to Soviet-era residents, is also not prohibited.

Socket outlets and switches can be installed by inserting the wire into a screw terminal and turning it inward (overzealousness may crimp the cable, spoiling the entire job), or by inserting the wire into corresponding slots on the switch housing (this type of fastening is characteristic of most modern European electrical goods).

IMPORTANT! The switch must be installed in the live wire circuit. Otherwise, fire safety rules will not be followed.

According to SNiP (Building Codes), the installation height of switches should be:

in schools or preschool institutions, and any room where children spend time switches should be installed at a height of 1.8 meters from the floor level;
in other rooms, installation at a height of 1.5 meters from the floor is allowed.

Switches should be installed on the side of the door handle.

Socket outlets should be installed according to these rules:

in schools and any other children's institutions – at a height of at least 1.8 meters from the floor;
in food service or retail establishments – no higher than 1.3 meters from the floor;
in other public buildings and residential rooms, the socket outlet height is chosen solely based on residents' preferences to ensure convenient connection of electrical appliances.

External Socket Outlet

For outdoor installation, a socket outlet must meet the following criteria:

The cable to the socket outlet must only be run concealed;
The socket outlet must meet the water protection standard IP65 or higher (where 6 indicates complete dust protection and 5 indicates protection against water jets);
It must be equipped with a special protective screen.

The installation height of an external socket outlet is highly individual.

Installing Double Socket Outlets

Installing double or even triple socket outlets is advisable based on the number of household appliances in use.

To install such a socket outlet, follow the detailed video instruction provided below.
