The sizes of distribution shields

The sizes of distribution shields
The choice of a distribution shield is an important task when arranging a house or apartment. The correct size of the shield directly affects the convenience of working with it, the possibility of placing the required number of machines and other equipment, as well as on the aesthetics of the room. But how to determine the desired size? It depends on several factors, and we will analyze them in more detail.
Number of machine guns and modules
The main criterion is the number of circuit breakers (machine guns) that you need. Each machine occupies a certain number of modules - the standard width of the module is 18 mm. Typically, shields are available with different number of modules: from small ones for 6-12 modules for apartments with minimal electricity consumption, to large ones for 36 or more modules for private houses with a large number of electrical appliances. Before buying, make a power supply plan, determining the number of consumption points (sockets, lighting, electric stove, water heater, etc.) and select the automatic machines of the corresponding power. Do not forget to take into account the place for the RCD (protective shutdown) and differential machines that provide additional safety.
Dimensional dimensions and type of installation
Distribution shields are of different dimensions, both in depth and in height and width. The depth depends on the number of modules and the presence of additional elements. The most common shields for overhead installations (attached directly to the wall) and for the built -in (installed in the niche of the walls). Built -in shields, as a rule, have a lower depth, but require preparation of a place to install them. Choosing the type of installation depends on the characteristics of your wall and personal preferences. Before buying, be sure to measure the place where the shield will be installed to make sure of its compatibility.
Reserve for the future
When choosing the size of the shield, do not save. Even if now it seems to you that the selected number of modules is enough, it is better to take a shield with a small margin. In the future, you may need to install additional machines for new electrical appliances or change the power supply circuit. The supply of modules will avoid unnecessary troubles and expenses for the replacement of the shield in the future. It is better to overpay a little and provide yourself with comfort and freedom of action in the future.
