How to Connect Wires to Screw Terminals
Strip about 3⁄4″ of insulation
Strip about 3⁄4″ of insulation from each wire using a combination tool. Choose the stripper opening that matches the gauge of the wire, and then clamp the wire in the tool. Pull the wire firmly to remove plastic insulation.
Form a C-shaped loop
Form a C-shaped loop in the end of each wire using a needlenose pliers or the hole of the correct gauge in a pair of wire strippers. The wire should have no scratches or nicks.
Hook each wire around the screw
Hook each wire around the screw terminal so it forms a clockwise loop. Tighten the screw firmly. Insulation should just touch head of screw. Never place the ends of two wires under a single screw terminal. Instead, use a pigtail wire (see page 31).
How to Connect Circuit Breakers
Shut off the main circuit breaker
Shut off the main circuit breaker in the main circuit breaker panel (if you are working in a subpanel, shut off the feeder breaker in the main panel). Remove the panel cover plate, taking care not to touch the parts inside the panel. Test for power (photo, right).
Open a knockout
Open a knockout in the side of the circuit breaker panel using a screwdriver and hammer. Attach a cable clamp to the knockout.
Hold the cable across the front
Hold the cable across the front of the panel near the knockout, and mark the sheathing about ½” inside the edge of the panel. Strip the cable from the marked line to the end using a cable ripper. (There should be 18″ to 24″ of excess cable.) Insert the cable through the clamp and into the service panel, and then tighten the clamp.
