Any cord-and-plug combination is subject to damage and wear. Lots of pulling and twisting, especially when a plug is pulled out by the cord rather than by grasping the plug itself, can cause the wires inside the insulation to break. This is particularly true with lamp cords because they use wire composed of multiple strands with a very small gauge. If the insulation protecting a cord cracks open, you could get a short circuit. It’s usually a better idea to replace these cords than to repair them.
Although it is less likely that you’ll ever have to replace a 240-volt appliance cord, these also can be changed out:
- Unplug the cord and unscrew the end that’s attached to the appliance, noting which wire (by color) went with which screw.
- Buy an exact replacement for the cord and plug.
- Connect the new cord to the terminal screws on the appliance, noting any color coding on the screws to match the individual wires (black to black, and so on).
