How Do You Extend An Electrical Wire?
Electrical wires are designed to carry current from one element to another. Most are made out of copper, which conducts electricity with very little resistance. If a wire is not long enough, you can splice it onto another. Provided you make a clean connection, the joint between the two wires will add only a little resistance. As long as you insulate the splice to prevent it from shorting, an extended wire will function just like a single wire. Strip about 1 inch of insulation off of the wire you want to extend. Strip an inch of insulation off a wire of similar thickness. Make a thin incision in the insulation along the wire from 1 inch down its length to the end. Peel back the insulation. Hold the bare end of the wire so that it crosses the bare end of the extension wire in an “X.” Twist the end of each wire around the other wire to form a single twisted wire. The wires should join tightly with no gaps between them. This is called a Western Union splice, and it’s one of the strongest w
