Wiring diagram in the apartment.

In the practical activities of any home craftsman, questions about the electrical circuit review periodically arise when you need to install an extra outlet, suspend a new lamp, or re-equip the room completely.

Immediately, the question arises: how is the wiring plan of the electric cables done, where should it be connected?


The situation is aggravated by the fact that the building is old, the apartment has been replaced by several owners, who have each made the repairs to their liking. As a result, all the wiring points are hidden inside the decorative coatings and the laying routes of the cables and wires are unknown.

Principles of construction of the electrical circuit in the apartment

All wiring is created by common methods and something, but different from all other joint schemes.

Required circuit elements

The basis for creating electrical wiring is an electrical distribution board to which electricity is supplied by the supplying organization. It can be installed at the entrance of a private house, in the staircase of the entrance of a high-rise building, either on one floor or directly inside the apartment.

The electricity in the housing panel from the input goes immediately to the electric meter - a device that takes into account its consumption. After that, it is distributed along the power lines to consumers by cables and wires.

To protect the circuits, automatic devices are used, integrated in the circuit inside the flat screen in front of the cable intended for the consumer.

Distinctive features

Each specific wiring diagram necessarily differs from similar developments due to the use of many designs of different models of electrical appliances, wires and cables with their installation according to standard or individual projects using different methods.

Ways to provide tension to consumers in the apartment

The electrical current of each appliance in working order is summarized in the panel of the apartment and taken into account by a meter crossed by the total load. Therefore, the main lines of the flat panel carrying the current have a thick section, which excludes the thermal overload of the wiring and the aging of the insulation.

For consumers from the flat panel, the wires are laid with a smaller section: the load that passes through them is less heavy. But the material and the cross section of the cores are chosen in directories taking into account the operating conditions of the wires and the power transmitted through them.

There are three possible ways to implement the schema:

cable (tires), when the common trunk is created through junction boxes, from which branches depart to electrical points (sockets, switches, lamps);
