The first step in basic electrical wiring or splicing is to turn off the power to the area in which work is being completed. To ensure safety, it is also important to use a junction box when adding new wires or splicing existing wires.
Splicing allows for extension of existing wires in order to move electrical outlets or ceiling lighting. Some essential tools for completing this job include wire clamps, wire nuts, wire stripper and cable ripper. The cable ripper removes the outer casing of the cable and expose the wires underneath. The wire stripper removes the colored plastic coating of the smaller wires. It is important to understand the various colors of the wires. Electrical wires are color-coded to ensure safety and prevent wiring errors. For example, white wires connect to other white wires.
Most home wiring is completed with either 12-gauge or 14-gauge wire. It is important to always use the same size wire when adding new wire connections. To add a new wire inside the junction box, locate the supply wire by following the white wires. All white wires will be tied to the supply wire. Remove one of the plugs and thread the new wire through the hole and connect with the supply wire. Use wire nuts to tie the ends of like-colored wires together, then close the junction box.
