Hi I'm James with JNC Home Repair. Today I'm going to show you how to repair a heavy duty extension cord plug. This is a fairly common problem around the house. You've got an extension cord that gets pulled around or yanked around and it starts shorting out or it doesn't, you know you plug it in and you've got something plugged into it and it works. Then it shuts off, and off and on and on and on and again. So I'm going to basically show you how to repair that. I've got one end that's already hooked up, but I've got another end just like we cut off the existing plug that was on it. You want to strip and splice your wire, you want to get two exposed sides here, just like so. Go ahead and twist those into place just like that, that way you don't have a bunch of frayed wires sticking out every where making contact with something you don't want it to make contact with. Keep them nice and tight, they're a lot easier to work with. Then what you're going to do, is this is your replacement plug right here. You're actually going to remove the set screw here which is you'll notice is a brass screw, which is going to be your hot wire. You've got another one over here, this is a chrome one, this is going to be your neutral wire. And you'll notice it comes right out, just like so. So what you do is you take your other end that you cut off, we always know that the brass is going to be the hot wire so you can tell right here there's just enough room to stick that wire in there, just like so. Right in there just like that. And you'll see there's a little bitty clamp there so when you tighten that screw down, it actually clamps onto that wire and it makes contact and it will actually go, it makes to contact to this so when you plug it into the wall. So you want to tighten that down and you want to do the other side just the same way, just like that. Go ahead and tighten that one down. And on this particular plug, your ground wire is right here. And actually this type of plug, this type of wire here doesn't have a ground wire inside of it. So what it's going to do is it's actually ground to the inside of this plug, and you'll see that there's a little bitty spring in there. And that's going to make contact with your ground terminal here. So when you line this back up, when you slide this back down here, you're going to feed this in like so. Open up just a little bit. Pull that around, pull that down. Make sure that your little spring inside there is right there, make sure it's lining up with that tab. You're going to fit it in there just like that. You're going to make sure that your little screws line up, and there's two screws that fit inside here. You tighten them down. Get this down back in there, tuck these bare wires, they're actually not bare wires but they're kind of exposed a little bit. You want to go ahead and tuck that back in and get all that stuff inside that plug. So you've got a good solid piece of rubber out here. Once you've got that back in there, you tighten up these little clamps. And that's how you change a heavy duty extension cord plug.
