How to install sockets in the houseToday, the height at which sockets and switches are installed, has no clear rules. The same applies to their number per room. As a result, quite often there are rooms where they are located in an archaic order and often in hard-to-reach places. As part of this material, we will try to figure out how to properly install sockets and switches, so that they are always available.

Regulations on the installation of sockets and switches

As previously mentioned, there are no regulations or rules for the installation of sockets and switches. "European standard" is no more than convention, because only safety and ease of use are important here. This is confirmed by the Code of Practice for the Design of Residential and Public Buildings (SP 31–110-2003), the latest edition of which was published in 2003. and Rules for electrical installation, which are prepared taking into account all the norms of the IEC, because the installation of electrical wiring should be based on these recommendations. From the first follow these installation rules:

  • switches should be placed on the side of the door handle at a height of 1 m from the floor;
  • the distance from the floor to the outlet should also be 100 cm, while its location does not matter.

Excerpts from Electrical Installation Rules

  • switches should be placed similarly to the instructions from the previous document, i.e. about the door handle at a distance of 1 m from the floor;
  • the switch can also be positioned under the ceiling, if there is a power cord going down to the recommended level;
  • in the kitchen, all power points should be at least half a meter from the pipeline and high enough from the floor;
  • in bathrooms, electrical installations should be installed at a distance of 60 cm from the sanitary equipment and the same distance from the floor.

Euro outlet significantly different from our products. The diameter of the pins and the distance between them in such an outlet is somewhat larger. The current strength is also greater: the euro is 10–16A, while the domestic one has two times less — 6–10A. Therefore, the first is much more profitable, since it is possible to connect several devices to it.

Installation of electrical components in the house

Electrical installation rulesFor you to understand - there are two ways to locate sockets and switches in the house. This is so-called. European standards and the good old, familiar to many, Soviet standards. Let's look at each in detail.

According to European standards, sockets must be at a distance of 30 cm from the floorand switches - 90 cm. But in reality, standardization as such has never existed, and this concept came into our lives along with European-quality repairs. Accordingly, he has a positive and negative side:

  • the socket does not “catch the eye” and does not interfere with anything, and the switch is located at the level of the lowered hand (90 cm from the floor) and it can be turned on without even looking and without application of any efforts - this is a plus;
  • in order to insert the plug into the socket, you will need to bend over, and in order for the switch to click, it should not be blocked by anything - this is a minus.

As for the Soviet standards, the opinion about them has recently been divided. Some consider them more convenient, others do not, but recently the number of the latter has begun to grow. Recall that then the installation of the outlet was adopted at a height of 90 cm, and the switches at the level of a human head, i.e. 160 cm As in the previous case, There are pros and cons:

  • the outlet is much more convenient to use, because it does not need to bend over, and the switch is located at eye level and does not prevent the placement of furniture - this is a plus;
  • constantly hanging power cords from the devices and the need to raise your hand to turn on the light and find the toggle switch with your eyes is a minus.

Tips for locating sockets and switches

Above, we have already said that the height of installation of sockets and switches according to the “Soviet” standard, in terms of convenience, has long been recognized by many as questionable. The notorious European standard began to give more preferences. Take, say, the same sockets, or rather, a block of them. He will not be so conspicuous than a bunch of sockets with tees and cords.

The same applies to the switches, which are located at the entrance to the room, at the level of a lowered human hand, at a height of 90 cm from the floor. Thus, it can be quickly found at the entrance to the dark room. And in rooms with greater length, it makes sense to install two continuous circuit breakers at different ends.

Switches and sockets that are not protected against leakage currents "to the ground" (RCD, difavtomaty), it is not recommended to install in toilets and bathrooms. The same applies to the outlet for the washing machine.

How to install them?

How to install a power outletBefore installing an outlet or switch, on the wall should trace their contour. If it is concrete, then the hole is made with a diamond core drill. Podrozetnik can be made both round and square. Special installation boxes are inserted into the finished holes. For their fixation, building gypsum is used, plaster or plaster glue. The box is fastened with sliding legs or screws, and then a plastic case is put on it.

Installation in a plasterboard wall is slightly different, different and necessary tools. In drywall sheets all holes are made in advance, where you want to spend the cable. To fix the sockets and switches, special pads are used, which should hold them on the sheet.

As for the installation with open wiring, such cases are extremely rare and mostly so fixed only temporarily (for example, during repair), since the wires affect the interior. Agree that it is much more pleasant to look at the beautiful wall, where everything is neat and aesthetic.

Installation recommendations

If you want to install the wiring and connect the sockets with the switch yourself without the assistance of third-party assistance, then follow the above tips and a number of rules that will allow to perform all the work without problems and, most importantly, safely:

  • European standard for the installation of socketsThe first step will be to prepare a plan where the future layout of the room will be reflected, and at the same time it should be made as accurate as possible so that later you can buy the required amount of cable. It is not very pleasant, when at the very peak of work there will suddenly be a lack of cable or, on the contrary, a lot of unused will remain;
  • also needed mark all the sockets on the wallsthat will be needed. It should take into account the height of the various devices;
  • fixtures for fixed fixtures (like a computer or the fridge) should be mounted so that they are simultaneously accessible and hiding behind the equipment;
  • No matter what you install, a power outlet or a switch, the order of connecting the contacts can not be confused! This is especially critical when connecting a three-prong outlet that has ground contacts;
  • sockets are installed at the rate of 6A, i.e. piece for every 10 m2 room area. In the kitchen of any area two sockets are installed;
  • sockets or switches should not be installed under or above the sink;
  • the wiring diagram should be selected in such a way as to completely eliminate network overloads;
  • frequently used sockets should be placed at a height of 30 cm, while taking into account that they can be freely reached the cord of the vacuum cleaner from anywhere in the room.

Summing up

So what have we learned today? Perhaps the most important will be the fact that clear standards Or there is no GOST standard regarding the placement of sockets, switches and wiring, but there are a number of recommendations that should be followed, primarily for security reasons. But the number of devices with switches must be such that the operation of household appliances and lighting devices is as convenient as possible, which should be taken into account when drafting a project.
