The distribution cabinet (box) is composed of distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box), which is the final equipment of the distribution system. Distribution cabinet is the general name of motor control center. The distribution cabinet is used for occasions with relatively scattered load and few circuits, and the motor control center is used for occasions with concentrated load and many circuits. They distribute the electrical energy of the upper distribution equipment circuit to the nearest load. This level of equipment shall provide load protection, monitoring and control.

1. Hierarchical management and respective responsibilities. The equipment Power Department of the distribution box shall number, register and file each low-voltage distribution box, manage it at different levels, clarify its responsibilities, and regularly conduct technical inspection and measurement on the distribution box. If any problems are found, they shall be eliminated in time to reduce accidents and be responsible to consumers.

2. The maintenance electrician shall conduct a comprehensive inspection when regularly inspecting the distribution box. If it is found that all parts of the distribution box are seriously heated, find out the cause of heating and fasten the loose wiring in time. In addition, if there are dust and sundries in the distribution box, it shall be cleaned in time to keep the distribution box clean.

3. The environment around the distribution box shall be kept clean. The maintenance or operation personnel of the distribution box shall not stack or hang work supplies or other articles within 1.2m in front of the distribution box door. In addition, there shall be no ponding around the distribution box, which is easy to cause electric shock accidents, and non professional electricians shall not disassemble the electrical components in the distribution box at will.

4. The operation of the distribution box shall be carried out in strict accordance with the operating procedures. During the use of the distribution box, it shall be strictly pulled and closed with load, otherwise a large arc will be formed to burn the distribution components or burn the operators of the distribution box.

This is the introduction to the main composition of high and low voltage distribution cabinet. I hope it will be helpful to you.
