The power supply of individual residential premises is not only the presence of a meter for accounting for electricity consumption and the presence of sockets and switches. This is a real home subscriber network.
The installation of electricians begins with the calculation of consumption and the plan of the location of lighting devices, measuring the length of the wire necessary for laying to power sources, rosettes and switches. When taking into account the length of the wire, it should be remembered about the reserve, which is usually about 10% of the total calculation.
Given the area of the standard one -room apartment requires about 700 meters of the electric wire of different sections. Of these, about 400 meters for the main wiring. Typical loads on sockets withstands the wire with a cross section of 2.5 mm. To provide the power stove with power supply, you need a cross -section of 6 mm, and for a washing machine or air conditioner, you should choose a wire with the cross section specified in the device passport. As a rule, it does not exceed 2.5 mm.
All power supply, should be mounted from the wire of one brand. The most important thing is to choose the right section of the wire. If the wiring is thinner than necessary, overheating will occur, which can lead to fire. The need for a greater section should be justified, otherwise it is just a waste of money.
To control the consumption of electricity, a meter must be installed. They come with the transformers and direct -flow. Both of the meter is allowed to use in a private house. It is easier to connect straight -flow and they are more often used in everyday life. For the complete and correct functioning of the power supply system, the assembly of the shield is required according to the project. Electric support is installed by an engineer. As a rule, independent assembly is prohibited. Only after the shield is fixed on the wall, you can start laying the wire. Even with minimal knowledge, this can really be done without outside help. But, if there are doubts and not confidence, then it is better to contact a specialist.
