How to shorten an AC power cable? Answered

I would like to shorten an AC power cable but want to make sure I do it the safest way possible. What is the best safe and easy method for doing this?

It's a cord that looks like this:

It's 12' long and i only need 3'

Please help!
Thanks :)


It's best to roll or tie it up. I just make a palm-sized coil and use a twist-tie to hold it together. Is there any reason it has to be cut short?

Thanks, but i need to put it in a casing with VERY limited space. The cord is WAY too long. Coiling it up won't do it, and I can't get a shorter cable.

Just cut the cable and crimp the wires on the inside that were cut together again

OR cut solder shrink wrap

Buy a rewireable plug, cut off the excess cable, wire on the new plug on the shortened cable, job done... :)

. Cutting the middle out of a cord and slicing the ends back together is very simple IF you know what you are doing, but it's not something that can be effectively taught here (it appears that you have little or no experience with electrical wiring). It's one of those if-you-have-to-ask-you-don't-need-to-do-it things.
. If GF's exquisitely simple solution won't work for you, I suggest buying a shorter cord or getting someone with wiring experience to shorten it for you.

Nah I think I can do it. I've done my share of electronics rigging etc, but just wondering what the safest way of doing it is. Would a butt connector suffice? Or is there some type of clamp on connector to just have new prongs? I know this is easy but I just want to be sure I don't create a fire hazzard so I want to use the proper equipment. Can someone throw me a bone? Thanks!

. If the splice will be inside your case, then wire nuts should work well, but don't put any stress on them. I like to put a few wraps of electrical tape (get the good stuff, eg, 3M Super 33+) over everything, but it's not really required if installed properly.
. If the splice will be exposed, I suggest crimp-on butt splices. I like the T&B brand, but there are other good ones. If you haven't used crimp-on fittings before, practice on some scrap wire before working on the real thing. A few wraps of electrical tape will finish up. You need to use a crimp tool to do it right - pliers just don't do the job properly.
