Ok, I'll be up front and tell you I'm a DIYer ... that seems to be a bad word around here, but I'll ask anyway.
I've mis-hit a staple and damaged the outer sheath of some cable. Stuff seems to be fairly brittle when its cold! It's about a 1/2" split. The inner insulation appears to be intact, but you can't see to much.
When I've done this on smaller runs, I just replaced the whole thing, but this is a long run and was somewhat of a PITA to pull.
So what are my options? Replace the cable? Wrap with electrical tape? Cut & splice isn't an option, because I can't put in an accesible box at this location.
FWIW, I have two instances of this. one in a 12/2 NM-b, and the other in some 14/3
