Got a job that i just need to replace a light and all the wiring in the box the insulation is breaking off. Any solution without new wiring.

Is there enough insulation left to push on a Wago and a pigtail? I will use a Wago sometimes when the dumba$$ before me cut the wire inside to box too short. It's easier than trying to twist together wires.

Cut the ceiling open. Install a non-metallic octagon near the fixture box. The goal is to get back to good wire. Splice new wire onto old wire in the new box, and run the new wire to the existing fixture box. Use the new fixture's canopy to hold up a medallion of sufficient size to cover your new splice box and any plaster wounds, but don't glue or nail the medallion up. Just like you were never there, except for a medallion that they may or may not have wanted.

As MDShunk advised. Can be a nightmare as often there are several wires in the ceiling box. That would be several j-boxes - up to a foot away (need good wire). Not bad if an attic.

Edit: Best to sell a $11,000 re-wire. Tell the owner all the light outlets are the same (they probably are). Or offer to sell him a dozen or so smoke detectors.

add a few inches of 90C wire to meet 110.3B, and you're good to go

might be but it works. If it's an old 14 u take a piece of 12 thhn and strip it's insulation and slide it on the old 14 conductor. Better then tape. Like I said not legal but it works. Also better then ripping someone's house apart in a pinch. Normally run into it in old houses in old light fixtures. By all means if u can get back to good wire do so but u can't sometimes.

what about the liquid tape that you brush on. Anyone ever use that.
Scotchkote? Hell, there's even a Scotchkote smiley face floating around here.

On a serious note, I don't think I would because that stuff dries really brittle, and I don't think it would stand up to the conductors being moved-around during any future work.

I don't think Skotchkote is rated for use by itself anyhow.

All I need to do is look at a can of that stuff and I get it everywhere. I can't imagine trying to use it inside someone's finished home, over my head. I think one stray drop of that stuff covers about 50 square feet. :laughing:

Or you can use some heatshrink and be done with it.

In fairness, one's a legitimately code compliant installation, and while I think heat shrink is safe, if an inspector was a ball-buster, I'm not sure it's defensible.
Yeah, I can't pretend like I've never put heat shrink on brittle wire, but that's on occasions where it wasn't brittle to where it enters the box. Nothing I'm especially proud of, but also nothing I'd advise anyone else to do in good conscience.

A quick but non legal fix is taking one size larger wire and stripping it long and then slide the new insulation over the old wire
That sounds absurd.
Ive done it a time or two. It'll be alright. :shifty:

Here is the legal version. :thumbsup:

Unless you have a complete and absolute disaster on your hands, heat shrink is all you really need.

You can usually get to good wire. Ripping someone's house apart is often the way to do it.

My experience says the wire has big problems in the box and it travels back 6 or more inches.

Fire is such a bitch.
