Code compliant method of repairing broken insulation inside a J/outlet box

Hi all,

Unfortunately, drama with my contractor continues... While I was inspecting his work, I found--quite horrifyingly--that in some outlet/switch boxes, the insulation of the hot/neutral wires is sliced/broken. When he was cutting the romex, he must have used a utility knife, did a sloppy job, and cut right into the inner wires.

In some places, only the outermost (transparent) sleeve is cut/compromised. In other places, however, the whole insulation is sliced such that bare copper is showing (on a hot wire at that!).

Putting aside my anger/disbelief/frustration for the moment... is there a code compliant way to fix this without rewiring the entire segment? I'm seriously contemplating firing my contractor finishing the work myself.

I read on some other forum that electrical tape is allowable, provided that the voltage/temperature rating is appropriate. But is it? I searched through the entire 2008 NEC and the word "tape" only showed up 64 times; and none refer to this situation. If you have any suggestion on which section to look, that would be greatly appreciated too.

Thanks!

Heat shrink tubing if you can't get him to do it the right way on his dime by replacing the damaged wire.

It takes a little care when stripping NM cable. I've used a knife forever and have only nicked a few wires.

You can use heat shrink tubing to repair the insulation.



Ray.....you're getting pretty quick for an old guy

Heat shrink is preferable over tape. However, I would push strongly for new cables. There are strippers made to do this task that do not damage the conductors. They are also faster than the knife method.
