Home Electrical Wiring...
Home electrical wiring can appear to be secretive, however have no dread: This accommodating aide will enable you to see how wiring functions and how to function with wire. Wires and cables of various sizes bring electricity to a house and route it to all the lights, switches, receptacles, and electrical appliances. Generally speaking, large cables deliver electricity to the house and smaller cables and wires distribute it throughout. Nearly all household wire is copper, though aluminum is occasionally used. A rubber, plastic, or paper-like coating, called insulation, serves as a barrier to keep the electrical charge (and heat) where it belongs—in the wire (this insulation is stripped from the ends of the wires where connections are made). Bare (non-insulated) conductors are used for grounding.
