Not sure if this is a stupid question!
I was using a metal "fish" line to run a TV cable through the wall. I was using the path of an existing electrical wire (circuit was off!) and "chaffed" against the wire a bunch of times. I can't see any obvious breaks but certain parts of the wire looked worn.
Any danger here? Do I need to repalce the wire? I am not sure how strong standard electrical wire is - It looks like a 1/2 diameter.
Please post - thanks - jg1234
