- Turn off any electrical power to the cables to be spliced together.
- Strip away three inches of the outer insulation on the end of each of the electrical cables to be spliced together. Use the utility knife to careful cut down the edge or the center between the wiring.
- Strip away one inch of the insulation on each wire inside the cables.
- Twist all the same colored wires (red to red, white to white, black to black, and bare to bare) together in a clockwise direction.
- Twist a wire nut on the end of each of the twisted sets of wires. Twist the wire nuts in a clockwise direction to lock them down.
- Wrap electrical tape around the wire as it enters the wire nut and up over the base of the wire nut to provide additional protection. Leave about a half inch of the end of the nut exposed to help see the color of the wire nut.

- Utility knife
- Wire strippers
- 1 package wire nuts

- It may help to identify the electrical wires and their use, by using the color coded wire nuts on the ends of the connections. Typically, red is for hot, white is for neutral, and green is for ground.
