Several grades of household power distribution box

There are three levels in the distribution of power distribution box, including grade one, level 2 and end level. Take the first class household power distribution box as a case, it is the core of the whole power distribution center, which is generally used in large electric field. It is mainly used for large-scale electric field, because there are many equipment in the home, so it will be equipped with such a class of distribution box. The second class household power distribution box will be more dispersed in application, and it is used in the situation of concentrated load and more circuits. It can distribute the power of a circuit of the upper level distribution equipment to the nearby load, and protect itself. The last level, which is mainly far away from the power supply center, is a distributed small capacity distribution equipment.
