Just did a remodel and have been wiring up plugs and switches. Noticed in a
couple of the receptacle boxes there are nicked THHNWires. In one case, a
Neutral and in the other case a Hot. In both scenerios, it is nicked about
3" or so after it enters to box. One one case it is conduit and conceivable
could be repulled. Pain though. In the other it is Romex and cannot be
replaced within ripping a wall open. I could just cut it real short and
pigtail with a wire nut but it makes me cry to cut them so short. I think I
know the answer, but can I use heat shrink or pro grade tape and cover the
nicks. BTW, bare metal is exposed in both nicks.
Is there a permanent splice that is more reliable than a wirenut? I think
this happened because they guy was using undersized boxes for homeruns and
it is very crowded.
"Ideal" brand has a splicer that is a brass sleeve-and-screw clamp with a
screw-on phenolic cap, the size of a large wire nut. I use these for
difficult splices like solid to stranded wire. Indispensible.
I don't understand why non-jacketed individual conductors would be nicked
unless they were pulled through a sharp pipe or box. Often jacketed
conductors get nicked trimming back the jacket, but why would these? Are you
sure there aren't nicks in the wire where you cannot see them?
If not, and you can 'reassemble' the nicked insulation around the nick, a
layer of 33 would be fine.
