Wire Nut Question

[Robert11]

Hello,

For terminating a live 110 V No. 14 wire in a metal box that isn't to be used anymore, can the wire just be clipped and a wire nut screwed over
the insulation ?

Or should the normal length of Cu be exposed as usual, and the nut placed over that ? Good idea for the Cu to be doubled over to provide two thicknesses ?

Thanks,
Bob

If the right wire nut is used for the job it will stay fine without folding it over or leaving the insulation in place.

Yes, makes it easy for the next guy to get a tester on it.

Besides, IMO striping the insulation is required.

running a wirenut down on insulation isnt very secure, the metal spring can cut the insulation, and it could be pulled off easily, stripping the wire makes it bite into the copper and a more secure cap in my opinion.

Try using electrical tape.

tape it

tape it

Don't forget to tape it!... just kidding!!:roll:

The worst is when people leave the "hooks" on solid wire, then just tape over them. It's difficult to get the tape off in that case. Seems like the hook digs into the tape when you try to remove it. I've done that myself many times, and curse myself each time.

Use the Tan ideals and throw out the yellows! The Tan is more versatile in application, (handles one to three wires, whereas yellow gets you two). If you cut one apart I believe you'll find the Tan has a longer, tighter, coil.

In all good conciousness though, follow 110.3(B)

One wire - Tan
Two wires -Tan
Three wires - Tan or Red
Four wires - Red
Five wires -Red
Blue wire nut? What'd you do?

I'm sorry, but I have to disagree. While you don't specify wire size, I have no trouble getting a yellow securely on three #12's or four #14's.

I've never been a 1-size-fits-all kinda guy. I hate seeing reds used to attach a single #18 fixture wire to a single #14; I use little oranges.

Rocky,
At least one brand of yellows are listed for use with 3 #12s.

I like the Tan's myself. They work well and go with almost any decor.

is there any reason why you cant disconnect it from the feed?

 

[Rockyd]

Alright Larry, I'll give you the oranges, they are effective, and efficient, for lights. Not going to go with the blues though....less no one is looking and I don't have to sign the work! Don't have any yellows in my box, and don't plan on to get any in the future!

Mark is right, tans go with any decor!

The ancient art of wirenutting is to always use plenty of electrical tape when done.......so says Confuscious.
