Standard single and double, corner, with protection, decorative - which one to choose for a private house? Tips + Videos Outdoor wiring is usually used in places where a hidden application can be difficult. The owners of country and country houses are often faced with such a task as conducting electricity to the detached buildings of their site.

This is street lighting, wooden and metal structures - sheds, garages, greenhouses, baths, where there is simply no need to lay a special cable. Not a single electrical wiring is complete without such an element as a socket, thanks to which you can easily disconnect and connect any energy consumer.

Sockets for external wiring, differ from sockets for the internal arrangement of their constituent elements inside the case and in that there is no need for a box.

Simple option

And this option is much easier to connect, you don't need to cut the wall and make a recess for the outlet. Moreover, to supply power, there is no need to dig a trench throughout the site and lay an armored power cable into it, you can simply use a regular cable attached to a cable and stretched between buildings.

Cases in which it is advisable to connect an external socket:

  • mounting device at the end of the repair;
  • installing the socket on a tiled wall , from tiles, panels, etc.;
  • when the wall is very thin and it is impossible to hide the wiring.

Pluses of the outdoor version

There are many pluses in the device of an external outlet.

This is both ease of installation, and aesthetic appearance, and not a great cost. However, do not forget about such moments as not hidden wires, which can be damaged quite often, because the cable has no protection. It is also possible for the contacts to come off, and this is known to be very dangerous in terms of electric shock.

For outbuildings, where not only lighting will be used, but also any devices will be connected, it is necessary to have an electrical panel with automatic devices and RCDs, which will protect against overloads, short circuits, etc. the central machine, you can easily de-energize any structure and be sure that while you are away nothing will happen.

Modern open wiring is a wire with internal PVC insulation with a varnished outer braid.
Overhead or external sockets, in fact, like hidden ones, differ in such parameters as permissible current, the number of connected phases, grounding, and the level of moisture protection.

Permissible current

The consignment socket can withstand from five to twenty amperes of the maximum current, in the case of a lighting network -220 V. The value of the limiting current must be borne in mind with the device, i.e.

. because the nature of consumption for each device is different. So, for example, an ordinary table lamp can consume no more than 0.3 amperes, but a vacuum cleaner or dishwasher can consume more than ten.

Note: If the network is not widespread, where the alternating current has a value of 127V, then all indicators of the devices are doubled.

Basically, all existing power supplies are single-phase, that is, with a neutral wire, then the sockets must also be used single-phase. All non-small-scale household appliances are designed for such food.


Grounding performs the task of preventing dangerous situations when a person touches the elements that have contact with phase wires. For example, to a metal body, a heating element of an electric hotplate.
It should be borne in mind that the installation of an appropriate outlet and grounding system will be advisable only if the consuming device has a special plug for grounding wires.

The structure of the electrical outlet

The external device of the outlet has a simple structure, namely, it consists of the following parts:

  • Ceramic, plastic or polycarbonate body, also called base. Elements conducting current are connected to it.
  • Mechanism or contact group. Retro sockets are equipped with a conductive mechanism, which can be brass or bronze. The bronze movement is considered to be of the highest quality, although it is quite difficult to find it.

    An obligatory element is the presence of a grounding contact.

  • The cover is the faceplate of the socket, its appearance. Mostly it is polycarbonate, but there are also wood, glass and metal.

Degree of protection

T. Since the installation work of external sockets is often carried out in outdoor conditions, that is, in moisture, in dirt, they must be made of durable materials.

Each device has a marked designation of the possible degree of protection of the mechanism. For example, an IP tag with two digits, the first digit indicating the degree of resistance to solid contaminants, and the second to liquid.

Note: Sockets marked with IP44-IP68 are recommended for outdoor use, and sockets marked with IP21 are quite suitable for indoor installations.


Standard single and double, corner, with protection, decorative - which one to choose for a private house? Tips + Videos Sockets for external wiring are divided into the following types: single and double, corner, with protection, decorative.

The standard single socket is a device with one plug entry.

The sizes are up to seven centimeters in height and up to five in width. The corner socket is designed for corner mounting. Double are a block of outlets with two connectors for a plug. Sockets with protective shutters to cover openings. The decorative device provides a variety of shapes and colors.

When purchasing such devices, consider the voltage ratings. It can be from 220V to 240V.

Installation of an external socket

According to the requirements of the PUE, the external socket must be located one centimeter from the wall surface.To do this, it is installed on a special plastic or plywood device called a display box. The box is attached to the wall.

There are external sockets with special mounting feet, these can be screwed on without any additional spacers.
Surface outlets are usually wired using a conduit to prevent damage to the wire. Today, the type of skirting board is increasingly used, which has an internal cavity to hide the wiring. The wires on the wall are fixed with screws or rollers.

Important: The sockets should not be located close to gas stoves, heating appliances and water sources.

The socket should be located at a convenient level for use. A fairly common location is just below the switch.

Important: Before starting any work with electricity, you must make sure that the wires are de-energized.

First, preparation and marking is carried out. The cover is removed from the socket, the side fixing elements are squeezed out.

The socket is disassembled into elements, it is marked on the wall where the holes for fastening will be located. Here it is advisable to use a level, otherwise the socket may be screwed on crookedly. Then the holes for the dowel-nails are drilled. A cable is pulled inside the socket.

After preparing the holes, install the socket.

Dowel-nails or self-tapping screws are inserted into the drilled holes, if it is a wooden wall, a mechanism is attached and everything is fixed. Those wires that are located inside the outlet are stripped. There are usually three wires.


Important: The connection of neutral and phase wires in all sockets and switches of the building must be connected in the same way. Otherwise, there may be confusion with the wires, and as a result, injury.

To prevent erroneous connection of wires, it is advisable to use a special probe or a regular battery with a tester during operation.
If the building has only two wires, the ground wire will not be needed.
