One other possibility as the cause of a broken copper wire, now I am talking 
about a solid wire which is not your case.  A copper wire is strong until 
there is a nick in it, then it breaks easily at the nick when flexed.  I 
wonder, if a number of strands of a stranded wire are nicked while one is 
removing the insulation could eventually result in breaking the wire, 
eventually.
