The Live Wire carries current to the appliance at a high voltage. In fact, it is that carries the 220v AC used by most of our home appliances. The earth wire is a safety wire and connects the metal case of the appliance to the earth. ... The neutral wire completes the circuit and carries current away from the appliance.
