Wiring: the electrical wires that transmit power from the breaker box, to the outlets and switches

Electrical Circuits

The electrons flow through the wire from source, to appliance or device returning to the source using the neutral wire. It’s essential to ensure that the wiring is installed and maintained properly, since faulty wiring can lead to electrical hazards like shocks and fires.
