Whats up with this extension cord?
#1
Was going through some extra extension cords I have laying around, and I found the one shown in the photos below. Its a rigid 14 gauge 25 foot cord. Bought it brand new 18 months ago, used it a couple of times to power some lamps and other light duty uses than put it away.

It has a poor connection inside the plug and has overheated. Take it back or replace the end yourself. DON'T USE IT LIKE THAT!!!

It only gets worse as you use it.

Looks like something shorted between either the hot and ground or hot and neutral. Do you have kids? I would ask them what they did with it. Wink

Edit: ^^^or that, good call Mikey.

This^^. To add a finer point, if I chose to replace the plug, I'd replace the socket on the other end as well. Someone's having QC issues.

BTW, you're looking at the earliest beginnings of a potential housefire, now prevented. Congrats!

Looks like the start of a wire-up for a anti-theft system for a Romney yard sign...lol.

Thanks. Electrical fires are my biggest fear....chances are I will just try and return the cord if I can as opposed to repairing it. Who knows if there is a problem inside the wrapped part of the cord.

Also, I was thinking about this last night and remembered that when I had a contractor here over the summer, he used this cord to run some of his power tools and halogen work lights. Maybe something he used was too much of a load for this cord??

So, just to be clear, is this problem a result of the cord being poorly constructed, or is there another issue at stake (i.e. problem with the socket it was plugged into), too much of a load being put on it, etc...?

What he said. Cut it off snd put a new end on it.

The conductor (wire) inside of the cord gets crimped to the blades sticking out of the plug end. The one that turned black is the neutral side of the circuit. For the return side of the plug to discolor like that, and not the hot side, tells me the that the crimp was not a good connection. Arcing has occurred and the more it is used, the worse the connection gets. It is a vicious cycle. Had the cord been used on something that had overloaded it, either the breaker would have tripped or both blades of the plug would look the same, if the crimps were both done properly.

I'm inclined to suspect a construction issue with the extension cord. If the load tried to go to high, the breaker should have tripped. 14/3 (14 gauge, 3 conductors) should have easily carried a 15 amp or lower load.

If residential electricity worries you, have you considered taking a night class or other course in residential wiring? It isn't rocket science, and understanding it will go a long way to easing your concerns.

You can easily make your own cords, which gives you the option of custom-making them for specific applications. I do this a lot.
