Plug Repair

May 9, 2010

Old plug, a melted mess

The old, derelict electric lawn mower melted the plug of the extension cord before we noticed that it was over heating.  I’m unpracticed at tinkering and fixing things that break, and I had pretty much decided just to buy a new extension cord.  I knew from a few minutes of online research that a new 100-foot extension cord would cost about $25 with tax.  Before spending that kind of money, I thought I’d try to repair the old cord by replacing the plug.

I am inordinately proud of myself for figuring out how to replace the plug all by myself!  I found instructions online at  And now I have a usable extension cord that works like new!  I hate being part of the throw-away culture, and I’m frugal at heart, so this little project was definitely a rewarding experience for me.

New replacement plug. Just open it by unscrewing it.

Cut off old plug, then remove 2 inches of the outer covering and insulation. You'll reveal three wires: white, black and green.

Strip 1/2 inch on each wire to reveal bare copper. Attach one wire to each of three screws: black wire to gold screw, white wire to silver screw, and green wire to green screw.

Slide screwed wires back into plug case and tighten the outside screw. You now have a working plug!

Please note this IMPORTANT information, submitted by an alert reader: “Wires are supposed to be wrapped CLOCKWISE around screw heads so that when tightened, the wire is pulled with it.

When they are attached counter-clockwise the screw pushes the wire off the terminal when tightened, which can lead to shorts, overheating, fire, fraying of the stranded wire, etc.”
