Neutral wire connection method in the distribution box
Neutral (N) Wire Connection: For 1P circuit breakers, designed to control only the live wire, the neutral (N) wire bypasses the breaker and is directly connected to the neutral busbar. It then supplies the neutral current to individual circuits. The wiring method of the neutral bar in the small power distribution unit mainly follows the following steps and principles: Position determination: In the small power distribution unit, the neutral bar is usually located on the left side and installed on an insulated base to ensure safety. These two conductors serve fundamentally different safety functions, even though they may sometimes connect. The connecting wires in water tight electrical box should be insulated and the joints should not be loose. There should be no exposed live parts in waterproof cable box. Ground faults occur when a hot wire touches a ground wire or metal box, creating a dangerous surge that trips.
