Making Electrical Connections

Making electrical connections is a fairly common procedure and needs to be done correctly and carefully. If you don't make tight connections, heat can build up between the conductors and cause a fire. Also make sure that the conductors you are connecting are of like metals and the power is OFF. Use a tester to make sure that line is not live. If you do not know how to test wires, click here. Select the appropriate gauge wire with the right casing for the job

Step 1:

First a note about safety: Make SURE that you are not working on live wires. If you are using cable that has a non-metallic sheathing (Romex), use a cable stripper.

Step 3:

Pull back the sheathing and expose the wires. Cut the sheathing off with a utility knife. Make sure you examine the insulation on the wires to make sure the stripper didn't tear it.

Step 4:

Expose about an inch of the bare wire by placing a wire stripper over the wire, clamp it over the wire, twist it once and then pull it towards the end of the wire. Repeat this for the other conductor. Pull the paper insulation from the ground as well.
