THE L N E MARK ON THE SWITCH SOCKET BASE
JUNON Switch and Socket factory explain the correct connection method of L N E LINE for you.
Facing the socket, the correct connection method of left neutral (N) right live (L) upper ground (E) should be used. Live line-L (red, yellow, blue), neutral-line-N (blue or black), ground-line-E (yellow-green). In low-voltage power network, three-phase four-wire system is used to transmit electricity, of which three-phase lines (fire-line) represent three-phase A, B and C respectively, and one neutral line N (zero-line).
In order to ensure the safety of electricity use, three-phase five-wire system is used instead of power supply in user's area. The fifth line is ground protection line PE (ground wire). One end of PE is buried deep underground with metal conductor near user's area, and the other end is connected with the ground connection of each user, thus playing the role of ground protection.
Ground wire is a reliable connection between the shell of equipment or electrical appliances and the earth. It is a good scheme to prevent electric shock accidents. Correct grounding can improve the anti-interference ability of the whole system. Most of the power sockets we use are single-phase three-wire sockets or single-phase two-wire sockets.
