To get the proper use out of wire nuts you must follow the color-coding that indicates which size wires the nuts will work with, then slice off the wires' insulation and thread the wiring onto the nuts. Go nuts with the helpful tips in this free video on home repair instructions.
Hi, I'm Chris Palmer. Today, I'm going to show you how to use wire nuts. When you're making connections using wire nuts, it's important to get the right size nut for the wire you're using. They're color coated. These red ones are for some bigger wires. These yellow ones are for smaller wires. There's a lot of different examples. It'll say on the package what wires, and how many of each wire, the nut will handle. I've removed some of this insulation off the Romex. You do that with your utility knife. You just make a slice along the edge. Or, you can make a circular slice around the perimeter, one or the other. Remove that, remove the paper that's in there. Here's your black, ground, and neutral. Line up the wire. In the case, I have 12 gauged, so I line it up with the 12 hole on my wire strippers. And, I want to strip about a half inch or five eights. If you're connecting to a stranded wire, it's not a bad idea to have the stranded wire a little bit longer than the solid wire. Essentially, what you do is, to make this connection, like maybe I'd be going black to black, or ground to ground, I just hold my wires together like that, and thread on the nut. Go ahead and twist it nice and tight. Although, it is possible to go too tight. But, you know, I'm putting a fair amount of pressure on there, and I can test that. That's a really strong connection, that's really tight. Again, it's really important to size the nuts to fit your wire. Like, this nut would be too big. Don't use the wrong size nut. I mean, it seems like it'll work, but it's worth it to get the right size nut. Thanks for watching. I'm Chris Palmer. That's how you use wire nuts.
