How to Wire Electrical Extension Cord Plugs


Sometimes the plugs on your extension cords may bend or snap, requiring that you either purchase a new extension cord or replace the plug. Wiring an electrical extension cord plug is an easy task that can be accomplished with just a couple of common tools and a few minutes of your time -- and like any simple household task you can do yourself, it will help save you money.

Things You'll Need

  • Replacement plug
  • Utility knife
  • Wire cutters
  • Cut the old plug off of the extension cord, at the bottom of the plug, by using your utility knife.

  • Split the extension cord's outer plastic jacket with the utility knife and slice the jacket approximately three-quarters of an inch down, exposing the three wires that will route to the new replacement plug.

  • Strip approximately one-half inch of insulation off each of the three wires.

  • Split open the casing of the replacement plug to expose the three wiring terminals.

  • Match the green wire from the extension cord to the green ground wire in the plug and attach it. Attach the white wire to the silver screw and the black wire to the brass or copper screw inside the plug's casing.

  • Wrap the wires around each of the terminals tightly, and then snap the casing of the plug closed to complete the procedure.
