was wondering when you?re working on an older electrical system, and come across a violation of current NEC. How do you know if it is a violation of the NEC for time it was wired? I know it is not required to meet current code if preexisting wiring. Unless you work on it, but how do you know if it met code when it was wired? I do not know NEC from 1980. Am I required to find out? Like one the grounded and grounding conductor share same lug in panel, and there is no separate grounding lug. I think this would have to be to code in 1980, but there are also some places down line where the grounded and grounding conductors are connected together. This I do not think meets code in 1980. I have not worked on either one, but if inspector did come along, and point out the grounded and grounding conductors connected. Would I be responsible? Am I required to know this was violation of 1980 code? Am I required to find out? I did point out problem to home owner, and I believe they are going to have me correct all of them. I just wondered if it was required, or not?
