I don't do a lot of residential work, haven't since the late 70s, but I'm doing a small repair project for my daughter's neighbor. Their lights were flickering a lot, starting about an hour after re-applying power (they had turned off the main out of an abundance of caution). I was just going to look everything over, assuming a bad or corroded connection somewhere, but I found nothing. So I told them to call PG&E to see if it was something on their side. They came out today and pulled the meter, finding that the meter socket was badly burned. The PG&E guy told them that it's too old to find a replacement socket (mid-60s construction) and they would need a whole new box and everything. It's a 100A GE meter/main unit, but unfortunately it's semi-flush, so embedded into the stucco wall. I think I can just swap out the socket itself and not have to rip out the box from the stucco. Has anything changed that much that it would be hard to find just the socket for a 50 year old GE meter/main unit? Can they refuse to reconnect to it if they don't like my work?
