Chewed wire insulation. Is there an approved repair?


Merry xmas everyone!

I recently found a section of wire that appears to have been chewed by a rodent. Normally I would just replace the section of wire. Unfortunately, this section goes into the wall and runs to the bathroom on the other side. I am trying real hard not to open up anything in the bathtoom and leave it undisturbed (I promised the wife I
wouldnt touch the bathroom). There doesnt seem to be any room to place a junction box either.

I work on cars for a living and have been repairing car wiring for a long time, especially rodent chewed wires. Of course they are different as far as current and voltage goes but seeing that the conductor on the wire in question is not damaged, could I use some ghick shrink tube to repair the damage? Im not sure what is legal as far as code goes but I can be sure the conductor will be covered when im done. I can disconnect the wire on the open side of the wall to slide the shrink tube over it as it terminates in an outlet box.

First off, address the rodent problem first. Otherwise, you'll be fixing more wires.

If the inner insulation isn't chewed, you can use electrical tape or heat shrink tubing. Maybe even a piece of split loom tubing.

Would it be possible to twist a new wire onto the end of this one in the bathroom and pull it through to a junction location?

It feels like the wire is probably stapled along the way to the bathroom switch.

I can see the copper for the hot wire (black) but it is intact. I cant imagine why protecting it with shrink tube and making sure its secure would cause any problems. I will wait to hear the general consensus on this first.

Thanks!

Heat shrink would be an appropriate repair

Fix the rodent problem cover with heat shrink tubing and get some flexible metal conduit with red heads installed on each end. They sell it in many sizes. That will protect the wire from future rodent damage. I use it wherever there is a rodent problem and I have to make a repair. I would also see if you can replace the whole wire if you can.

In order to use heat shrink tubing you need to disconnect one end of the cable.

Also maybe you could abandon the wire and fish in some MC? If it looks like that where you can see it. It's possible it looks like that where you can't see it too.
