A distribution box is an electrical equipment used for distributing electrical energy and controlling switch devices in circuits. It usually contains various electrical components inside, such as circuit breakers, isolation switches, fuses, contactors, etc., used to connect and disconnect circuits, as well as functions of control, protection, and monitoring. Distribution boxes are usually installed on walls, floors, or other fixed structures to distribute, control, and protect electricity. It can introduce power and then distribute power to different electrical devices through internal electrical components, such as lighting fixtures, motors, sockets, etc.

A distribution box, also known as a distribution panel or cabinet, is a device that centrally controls and manages electrical energy. Its main function is to distribute electrical energy from the high-voltage system to the low-voltage system, and monitor, measure, and protect the power during this process. The distribution box is equipped with various electrical components inside, such as circuit breakers, contactors, fuses, instruments, etc. These components work together to ensure the safe and reliable transmission of electricity to various electrical equipment.
