How do I replace the end on my extension cord?

Replacing the end of an extension cord

  • Buy the appropriate type of replacement plug or socket. If the extension cord is a 3 wire type (with grounding connection), buy a 3 pronged replacement. Likewise, make sure that the replacement is rated for the same load as the cord; if you have a heavy-duty cord, ensure that the replacement is rated for heavy-duty loads.
  • Cut off the broken plug or socket with the knife.
  • Strip half an inch of the outer cord casing from the cable near the cut end. Be careful to cut only the outer casing and avoid damaging the interior wires.
  • Strip half an inch of insulation from each of the individual wires within the casing.
  • Disassemble the replacement plug or socket. Generally, replacement plugs consist of a plastic outer case that contains screw-down terminals to which the individual wires attach. Some plugs come from the store in a disassembled state, while others require unscrewing a screw or unsnapping a case to access the interior screw terminals.
  • Screw the exposed extension cord wires to the terminals inside the replacement plug or socket. If your replacement plug has screw-type terminals, loop wire around the terminal and then screw it down. The green wire is the ground wire, the white wire is the neutral wire, and the black wire is the hot wire. Light-duty interior extension cords often lack the ground wire, but if a ground wire is present, be sure to connect it. Many replacement plugs come with color-coded terminal screws, making connection to the right terminal easy. If in doubt, check the wiring diagram that came with the replacement plug or socket.
  • Put the plug or socket casing back together around the terminals. Depending on the exact model you have, this may require snapping a plastic case into place or screwing in a retaining screw. Make sure no bare wire is exposed.
