Fix for a Damaged Cord
Accidentally cut your good, heavy-duty extension cord? Replacement cords are expensive, and you can save money by just repairing it. Instead of splicing, add a new plug on the piece of the cord with the receptacle and a new receptacle on the piece of the cord with the plug.
Project step-by-step (3)
Technically, you’re not supposed to splice extension cords. Even if you solder the wires, wrap each wire with electrical tape and encase the whole splice in heat shrinkable tubing, it still won’t have the abrasion resistance of a new cord. Plus, it’s not permissible under the National Electrical Code.
Make Two Cords From One
Instead of splicing, if both sections are long enough to be worth saving, just buy a high-quality plug and receptacle and make two cords out of one. Add a new plug on the piece of the cord with the receptacle and a new receptacle on the piece of the cord with the plug.
New Extension Cord Ends
Be sure the new ends are rated to carry the same load as the old cord and that both have built-in strain relief clamps. Otherwise, just buy one end and accept the fact that your 100-ft. cord is now only 92.56 ft.
