When repairing or building, many apartment owners are wondering how to properly place switches or sockets in the apartment. Indeed, not only the convenience of using them depends on this, but also the safety of operation, and, consequently, health.

To correctly deal with this issue, we will consider the rules of their placement that existed in the recent past and the new trends that came from other countries.

In Soviet times, it was customary to install lighting switches in residential premises near the entrance to them at the height of the shoulders of an adult or placed under the ceiling. And the sockets were mounted in the wall at a distance of 90-100 cm from the floor. Wall switches were located at a level of about 160 ÷ 180 cm from the floor. This distance was considered the most suitable, optimal for controlling light. Example of placement of the switch block ...

Convenience of lighting control is one of the basic rules that guide the installation of electrical wiring. If the room is relatively small in area, then to control the various lighting devices mounted in this room, one light switch is enough.

In the event that the room is large enough or extended, then for the convenience of controlling the fixtures installed in it, it is more expedient to provide for the possibility of their inclusion from two or more places. To realize this possibility, passage and cross switches or bistable relays are used. Below we briefly describe both methods of controlling lighting devices, and give their main advantages and disadvantages. Through and cross switches have the principle of work similar to traditional switches of lighting. Switching lighting circuits ...

The current rules for the installation of electrical installations have increased requirements for the reliability of the connection of protective neutral wires and the electrical contacts created by them. In this case, the connection of electrical appliances should be done through a branch, and not a cable.

To understand the difference between these methods, imagine a fruit tree with a grafted branch. Branches that have grown naturally and extend from the trunk can be considered as one with the tree. The term branching is suitable for them, and the scion is created artificially - this is a train. Under a loop in the energy sector, it is customary to consider a piece of wire connected to an electrical wiring to create a specific electrical circuit.

In other words, the PUE requirement can be explained as follows: the zero conductor protector must be intact throughout its entire length, which means a ban not only on its creation ...

In practice, there are many ways to connect electrical outlets with wiring. During their implementation, different goals can be pursued, from austerity of materials and means to reliable, long-term and safe operation of the equipment.

Considering the growing needs of the population for the use of powerful electrical appliances in everyday life, we should dwell on the most favorable electrical circuit for a home network that provides maximum safety during operation. It should be divided into two components of the system: the power unit, which provides power to household appliances through outlets, the lighting system, separated from the operation of the power unit. To create the power circuits of the internal apartment panel, circuit breakers are mounted according to the number of necessary connections.A cable is laid from each machine ...

The timer socket is one of the most useful and at the same time affordable home automation elements. Such a simple device can be very useful for you.

The timer socket can turn on the heater well in advance of your arrival, provide a comfortable temperature, and it can also control devices on a schedule. For example, the inhabitants of aquariums and terrariums need to turn on the light and compressor only at certain times. Also, in the long-term absence of the house, a timer-socket with the function of random switching on, will allow you to create an effect of presence in the house, which will serve as a certain protection for your house. In these and many other cases, timer sockets are simply irreplaceable! There are two types of timers: electronic and mechanical. Mechanical timers are easier to operate. They are engaged in the work of the program ...

About a common wiring malfunction, when the 220 V phase is in both sockets of the socket About why this is happening and why it is dangerous. First-person and a bit informal.

There is one characteristic electrical wiring failure that can confuse a beginner or inexperienced electrician.

To clarify what I’m talking about, I’ll give a story of one of my friends: “My neighbor comes to me on Saturday - my lonely grandmother. And asks to deal with the electrician in the apartment. Say, nothing works, but the lights did not seem to be turned off. Well, I, of course, go to the site and check the circuit breakers. Everything is in order, all machines are on. I take the indicator: the phase is passing. I go into the apartment to my grandmother, I check the first outlet. The first connector is the “phase”. I check the second connector - also a "phase"! Where are the two phases from? ...

The need to transfer sockets and switches, as a rule, arises after moving furniture in the apartment, or when bringing the wiring to the so-called European standard, according to which the sockets are installed at a height of 20 - 30 centimeters, and switches at a height of 90 - 120 centimeters from the floor.

If you want to lower the outlet, and the wiring is done in a coupler, then just install the new installation box in the desired location and shorten the cable to the desired length. The situation is more complicated when you need to increase the cable. Two tasks immediately arise here. How to connect cable cores so that the connection is high-quality and durable, and what to do with the old installation box.

The worst solution to this issue is to connect the cable, for example, twisting the cores, insulating the twist, cover the wires with alabaster in the old installation box and forget where this time bomb is ...

Installation boxes are intended for installation of plug sockets and electrical wiring switches of an apartment (house) in them. Installation boxes are mounted directly in the wall of the room, and a socket or light switch is installed in it.

Some types of installation boxes have enough space for mounting in them not only sockets (switches), but also other elements of the electrical wiring of the apartment. For example, if it is necessary to connect several sockets with a loop, a terminal block is installed and connected to the installation box, and then the socket.

Depending on the installation location, several types of installation boxes are distinguished: boxes for installation in drywall and hollow walls, boxes for brick or concrete walls, boxes intended for pouring into concrete (used in industrial enterprises). The first type of installation boxes is characterized by the presence of special clamps ...
