If the wiring is faulty it may be carrying the same electricity as the live wire. Therefore, it is important to know how to identify live and neutral wires to avoid an accidental shock. Also known as hot wires, they carry the electric current from the power source to your device. “Hot or ‘live’ wires carry 120 volts (V) of electricity from the power source (electrical panel) to a device like a switch, outlet, light fixture or appliance. Make sure the wires are correctly connected to their corresponding terminals. The three main wires—live, neutral, and earth (ground)—play specific roles in this process. New Wiring. While the live wire carries power from the source, the neutral wire returns electricity to the source, completing the circuit. The electric potential between the live and neutral wires enables electricity to flow. An old electrical wiring colour scheme doesn’t necessarily mean that wires are unhealthy. My HDB flat uses the older wiring code, whereas new appliances uses new ones. The hot wire carries the high voltage from the power source, and the neutral wire completes the circuit by providing the return path. It typically transports around 120 or 230VAC, depending on the region. Live wire identification: Understanding the significance of the brown wire.
