The main criteria for selection of the switch box

installation method

The first thing you need to decide what to pick up the design of a switch - external installation or embedded.If you are in an apartment or house walls of plasterboard, it is better to choose recessed electrical box, which is not so much spoiled the interior of the room.However, if the walls are concrete, and there is no way to make a niche, may be installed surface-switch box.

In the country also need to look at the circumstances.For example, in a wooden house or a bath is better to put a more secure invoice flap.

As for the garage or industrial premises, then you should not worry, and mounted on a wall mounted switchboard, which is mounted on the procedure easier.

manufacturing material for selection of the electrical panel, special attention should be paid to the material from which it is made - plastic or metal.The plastic shield is much more beautiful, so it is recommended to choose an apartment, private house or office.

Metal housing more durable, robust and reliable.This option is better to pick up the electrical panel for industrial premises, garages or streets.

Please note that if you decide to choose a plastic electrical panel, be sure to buy a product from a reliable manufacturer.Cheap Chinese switchboard quickly turn yellow and also famous for the fact that simply break down.

number of modules

Another equally important criterion for selecting the electrical - the number of modules.To choose the right size of the panel, you need to start to make the wiring diagram in which the exact number of machines, RCD, Emergency circuit breakers, as well as to determine whether the counter to stand inside the electric board.With Mapping select the number of modules is not difficult.Note that the width of a single module - 18 mm (width of single-pole circuit breaker).To properly perform the calculation refer to the following values ​​(the number of modules, which is one unit):

1. Electricity meter - from 6 to 8.
2. -phase RCD - 5.
3. single phase RCD - 3.
4. three-phase circuit breaker - 3.
5. Bipolar machine - 2.
6. Single-pole automatic - 1.

Typically, apartments, if the meter is installed on the landing, it is enough to select the electrical modules 12-16 (better to take with a stock, you never know, suddenly you will want in the futureconnect voltage relay for the protection of the wiring).If the two bedroom apartment and the counter is at you in the corridor, it is better to choose the body is not less than 16 seats.

In a private house, in fact, as in the country, electricity consumers more, so it is recommended to put the electrical panel to a larger number of modules - at least 24. Although, again, it will dependfrom the chosen wiring scheme.Did you put the lights on only one machine, and may be such that each room will be a circuit breaker.In addition, you need to take into account the voltage at the input - 220 or 380 volts.For three-phase electricity meter, and automatic RCD will need more space.

If you have difficulty with the method of choice for the switch board at home, be sure to Charting go to the store and there already, consulting with a specialist to choose the right size of the shield!

Manufacturer

Well, the last selection criterion - the manufacturer of the product.If you do not know which company to choose the electrical panel, we are sure to give preference to the following manufacturers:

• ABB;
• IEK;
• Makel.

These three company boards often used in electrical work.Electrical switchboards ABB highest quality, IEK and Makel slightly inferior competitor, but the price will be cheaper.

If you want to choose a beautiful and at the same time reliable switchboard for the house or apartment, prefer Greek FOTKA manufacturer.The range of products you can see in the photo example themselves:

What else is important to know?

For office, which will be installed only 2-3 circuit breakers, be sure to pick up not the electrical and compact plastic box which is smaller in size and, of course, price.

Another important point - the door of the electrical panel.It is better to be transparent, becauseIn this case, you will not need to open the electrical panel for the visual inspection of the machine, if the light is lost.
