Electricity supply of the apartment

Overhaul is always associated with the need to replace the electrical wiring. This stage requires special attention and responsibility. It is important not only to provide housing with electricity, but also to make it safe. Short-circuits lead to fires, and electric shocks lead to detrimental health consequences. However, the installation of electrical wiring in the apartment can be done independently.

A consumer connection diagram will be required, as well as safety requirements. All this will be discussed further. This publication describes in detail how to correctly develop your own scheme, adapted to work taking into account all the features of your home. Here you will find out what is needed for this.

The electrics in the apartment are laid in a special order. Each room has a number of characteristic requirements that must be taken into account so that the stay is not only comfortable, but also safe. Naturally, we will tell you how to select components, calculate the parameters of cables and connect all the elements into a single workable system.

Distinctive features of modern electrical wiring
When electrification became ubiquitous at the beginning of the last century, progress broke not only into the production sphere, but also into human life. And with the onset of the current millennium, it is already impossible to imagine housing without televisions, computers, and other kitchen and household appliances. The electrical wiring in the apartment is a hidden network of wires through which electricity is supplied to each consumer. Only if earlier it was necessary to bring wires to the light bulb, now there are much more requirements.

And the design stage already causes difficulties. We have to make calculations. The main factor is the load that is possible when all household appliances are turned on. Modern electrical wiring consists of branches, each of which is intended for a certain number of consumers. We need protection against circuit, grounding, etc. It's good when there is a design project, where you can see how many lighting points will be in the rooms, what household appliances are planned to be installed. It remains only to summarize their power consumption. The installation locations of the switches and sockets are already known.

Professionals with experience in the development of power supply cope with the task without much difficulty. But wiring for a beginner seems like a kind of art based on scientific knowledge. You can't do everything at random or the old fashioned way. Then, after the repair is completed, the interior will be spoiled by lying cords, extension cords, tees. To hide the new lines, you will have to break the finish. But even cosmetic repairs cost a lot of money. Therefore, the first thing to do when you need to lay the wiring in the apartment with your own hands from the dashboard to the consumers is to develop an individual scheme.

This is a plan (drawing), which graphically shows where a certain number of switches, sockets, lighting fixtures should be located. The schematic diagram is developed by each electrician who is entrusted with the work. However, the wiring can be done in-house. The main thing is to correctly calculate the planned load, and divide the cables into groups. The system must include an electricity meter. You will also need protection devices, grounding, if this was originally designed in an apartment building.

If we consider the components, then for the installation of electrical wiring in the apartment with your own hands you will need:

Automatic protection devices. They are installed in the control room. The goal is to protect electrical appliances, the health of residents and the integrity of the property from the effects of short circuits and power surges.

They must be insulated, different in color and of sufficient cross-section to withstand the maximum permissible load. To do this, you will have to make calculations depending on the material of the core (aluminum, copper).
Sockets and switches. Modern electrical circuits of an apartment assume the presence of grounding, for which special lines and connectors are provided. If the house is old, the contacts simply remain unused.
