How to Change the End on a Power Cord
- 1). Cut off the damaged plug from the end of the extension cord using wire cutters.
- 2). Slice vertically along the cable jacket. The slice should be about an inch long, allowing enough wire to work with when connecting the wire to the replacement plug.
- 3). Strip the insulation about 1/2 inch from the ends of the three wires using the wire strippers.
- 4). Unscrew the screws on the front of the replacement plug using a Phillips screwdriver, and separate the top part from the bottom part. The bottom part will have a hole that will allow the wire to slip through. Slip the bottom part of the plug onto the wire.
- 5). Connect each of the three exposed wires to one of the terminal screws on the top part of the new plug. The green wire connects to the green terminal, white connects to silver, and black connects to brass. Depending on the model of plug, the wires will need to be either wrapped around the terminal screws or they can be placed inside them and clamped down. If you are wrapping the wires, make sure to wrap them clockwise around the respective terminal screw.
- 6). Tighten each of the terminal screws using a flat-head screwdriver to hold the wires in place.
- 7). Connect the bottom part of the plug with the top part, and tighten the screws on the front of the plug with the Phillips screwdriver.
- 8). Plug the cord into an electrical outlet, and then plug a circuit tester into the other end of the cord. If all of the corresponding lights for connection and grounding light up, then the cord has been repaired properly.
