As the core guardian of the power system, the distribution box plays a crucial role in the transmission and distribution of electricity. By understanding its definition, function, classification, working principle, and application fields, we can better understand and use distribution boxes, providing strong guarantees for the stable operation of the power system.

The working principle of a distribution box is mainly to distribute, control, and protect electricity through internal electrical components. After the power is input into the distribution box from the power source, it is first controlled by the main switch, and then distributed to various electrical equipment through various branch switches according to different electricity needs. At the same time, the distribution box is also equipped with various protective devices, such as overload protection, short circuit protection, leakage protection, etc., to ensure the safe use of electricity.
