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.

According to different usage scenarios and voltage levels, distribution boxes can be divided into various types. Common distribution boxes include low-voltage distribution boxes, high-voltage distribution boxes, power distribution boxes, lighting distribution boxes, etc. Each type of distribution box has its specific application scenarios and functional characteristics to meet the needs of different users.
