Decoding Wires and Cables

Wire, cable, and conduit comprise the electrical infrastructure in your home. Selecting the appropriate size and type and handling it correctly is absolutely necessary to a successful wiring project that will pass inspection. Copper or aluminum wires are the primary conductors of electricity in any home. The electricity itself travels on the outer surfaces of the wire, so insulation is added to the wires to protect against shock and fires. The insulated wires are frequently grouped together and enclosed in sheathing according to gauge and function. Multiple wires enclosed in sheathing form a cable.
