I'm really surprised that the electrician didnt insist on upgrading the whole thing. Here its hard to get any small jobs done because, under their "new" rules, if an electrician does any work on a home he has to bring the whole thing up to the new standards. Its a royal pain. I wanted to have one of my apartments re wired and the inspector insisted that I would have to put in a new 400 amp service for the entire building, not because there was anything wrong with the present one, but because it wasnt installed in the way that its done now. Nedless to say the work wasnt done. There is no way I'm paying $10 - 15,000 to change something that is in perfectly good shape. Had it been unsafe or dangerous that would be a different story, but you cant expect something put in 40 years ago to be the same as todays.
