In our daily lives, wires are indispensable electrical equipment, and the knowledge about wires gives many people a headache. In particular, people often ask, is the black wire a live wire, a neutral wire, or a ground wire? Below, ZhuFeng Wire and Cable will explain it in detail.
The black wire usually represents the live wire. Live wires are wires that carry current and carry the voltage of the power supply system. Live wires usually have voltage, so when installing and using electrical appliances, be careful not to touch them to avoid electric shock accidents. Black wires are usually connected to electrical appliances such as switches and sockets, and can start and stop electrical appliances by controlling the on and off of current.
Secondly, the neutral wire is used for grounding in the circuit. The neutral wire serves to lead the current from the electrical equipment back to the generator and completes the circuit. Usually, the neutral wire is blue to distinguish the live wire. When using electrical appliances, the neutral line should also be protected to avoid touching the neutral line or causing poor contact of the neutral line, causing electrical failure.
The ground wire is an important line. The ground wire is to prevent abnormal currents from being quickly introduced into the ground when electrical equipment fails such as leakage or short circuit. Typically, the ground wire is yellow-green. The ground wire must be connected to the ground electrode to ensure safety. In the event of electrical failure, the ground wire can provide reliable protection and avoid personal injury.
