Owner was changing kitchen light to put in a ceiling fan and found live wires that were cracked and bare (baseboard heated apartment).
Wire was stripped back and the further back the wire was fine but will be to short to put back in the box.
Can you put some sort of heat shrink around the wire or should it be completely replaced or a junction box in the ceiling still being accessible to extend the wire.
It really looks like all the wiring needs to be replaced. Other boxes reveal the same cracking. House is around 50 yrs old.
Thanks for the answers.
The wire(s) will be replaced. Seems that is the only spot for that kind of wire. Lots of other issues though. wire placed behind baseboard and not protected, neutral and hot wires crossed etc, etc,
