Facing the socket mould, it should be wired according to the correct connection method of left zero (N) right fire (L) and ground (E). Live wire-L (red, yellow, blue), neutral wire-N (blue or black), earth wire-E (yellow-green). Power is transmitted in a three-phase four-wire system in a low-voltage power grid, in which there are three phase wires (live wire) respectively represent A, B, C three-phase, a neutral wire N (neutral wire). In order to ensure the safety of electricity use, the three-phase five-wire system is used for power supply in the user area. The fifth wire is the grounding protection wire PE (earth wire), one end of which is buried in the ground with a metal conductor near the user area. , and the other end is connected to the ground contact of each user, which plays the role of grounding protection.

The ground wire is a line that reliably connects the casing of the equipment or electrical appliances to the ground, and is a good solution to prevent electric shock accidents.

Proper grounding can improve the anti-interference ability of the entire system.

Most of the Chinese-style five-hole power sockets we use are single-phase three-wire sockets or single-phase two-wire sockets.
