The general distribution box is generally set in the power load center. The distribution box is set at the place where the electrical equipment or load is relatively concentrated, and the distance from the switch box is generally no more than 30. What are the conventional setting methods of the distribution box? The distribution box is divided into three levels: general distribution box, distribution box and switch box. According to the controlled load distribution box, it can be divided into power distribution box, lighting distribution box and hybrid distribution box. 1. The general distribution box is generally set in the power load center. The distribution box is set at the place where the electrical equipment or load is relatively concentrated, and the distance from the switch box is generally no more than 30m.

2. For the convenience of use, the distribution box and lighting distribution box are generally set separately. If a mixing box is used, the power supply and lighting circuits are set separately.

3. The main distribution box is distributed by the final distribution box. For the sake of safety, the distribution box and switch box are provided with grounding safety protection measures during installation,

Attention shall be paid to the following aspects when using:

(1) The metal box, metal electrical mounting plate of the distribution box and the metal base and shell that should not be charged in the box shall be connected to neutral protection;

(2) The protection zero line shall be connected through the terminal board;

(3) The main distribution box is equipped with main disconnector and shunt disconnector, main fuse and shunt fuse, or main automatic air switch, shunt automatic switch and leakage protector.

(4) If the leakage protector has the functions of overload protection and short circuit protection, it is generally no longer equipped with shunt fuse or shunt switch.

Distribution box is a low-voltage distribution box, which is composed of switchgear, measuring instruments, protective appliances and auxiliary equipment. It is installed in a closed or semi closed metal cabinet or panel. The measuring instruments mainly include electric energy meter and current transformer. Protective equipment mainly includes leakage protector; Lightning arresters and fuses. Switch cabinet mainly includes load switch, partition and basic knowledge of the use and classification of distribution box.
