When installing and using the distribution box, it is necessary to follow relevant safety regulations and operating procedures to ensure the correct installation and use of the distribution box. At the same time, regular maintenance and inspection are also necessary to ensure its normal operation and extend its service life. The distribution box is an indispensable part of the power system, which is of great significance for ensuring the normal operation of the power system and the safe and reliable operation of electrical equipment.

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.

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.

Distribution boxes are widely used in fields such as homes, commercial areas, industrial areas, transportation facilities, and public facilities. In the household sector, it converts high-voltage electricity from transmission lines into low-voltage electricity suitable for household use, and transmits it to various households through cables; In commercial areas, industrial areas, and transportation facilities, distribution boxes are mainly used to provide electricity for various facilities and ensure electricity safety and stability.

The distribution box has a protective function, which can automatically cut off the power supply in case of short circuit fault or abnormal situation of electrical equipment; It also has an indicator function, and the indicator lights on the panel can emit red, green, and yellow light to display the circuit status; In addition, the distribution box can also perform operations such as conversion switches, isolation transformers, measuring instruments, and branch circuit breakers.
