What are the requirements for the installation of low-voltage distribution cabinets?

Hello, I am helping you to inquire about the relevant case and will reply to you immediately.

What are the installation requirements for low-voltage distribution cabinets 1. The box materials of low-voltage distribution cabinets, distribution boxes and switch boxes are generally made of steel plates and insulating boards, but wood materials should not be used. 2. The electrical box and switch box should be installed upright, firmly, and should not be inverted or skewed. The bottom of the fixed distribution box and switch box is perpendicular to the ground, which should be greater than less than or equal to; The distance between the bottom of the mobile distribution box and the switch box and the ground should be greater than or equal to less than or equal to.

3. It is strictly forbidden to connect the power cord into the low-voltage distribution cabinet with a bolt. 4. The distance between the electrical boxes should not be too far. The distance between the distribution electric box and the switch box is not more than 30m.

The horizontal distance between the switch box and the fixed electrical equipment should not exceed the level of each electrical equipment, and each electrical equipment should have its own special switch box. Each electrical equipment on the construction site should have its own special switch box, and must meet the requirements of "one machine, one gate and one leakage", and it is strictly forbidden to use the same switch to directly control two or more electrical equipment (including sockets). A leakage protector must be set up in the switch box, and its rated leakage action current should not be greater than 30mA, and the leakage action time should not be greater than.

What I want to ask is what are the requirements for the switch in the phase change low-voltage outlet cabinet of formal electricity.

Personally, I understand that the circuit breaker is selected for the outgoing switch in the institute, the first-level leakage protection should refer to the main distribution box out of the low-voltage cabinet, the total distribution box of the construction unit should be the second-level leakage protection, and the leakage protection switch connected to the electrical equipment should be the third-level protection.
