Okay so I'm in the middle of a remodel and I was asked a question that well I found very interesting and couldn't find an answer in the code book. Perhaps you guys can help me out with it. Well the house was rewired in the 60's i'd say all romex with reduced grounds. Had to add a few new plugs upstairs and know that we have to run a new feed for the plugs since we are adding some and can't add to the violation already there we have to run freash feeds.
"rewired in the 60's i'd say all romex with reduced grounds"
"can't add to the violation already there"
Which is it ?
Is there already a violation or was it installed correctly in the 60's ?
If it was installed correctly in the 60's, then it isn't a violation today as long as it stays outside of your scope of work.
If you were trying to power a new circuit from an improperly grounded
panel, the new circuit would
also not be properly protected/grounded and the violation would
spread into the new scope of work. . The violation would be incorrect grounding
of the new circuit and you would need to either expand your scope of work and correct the panel grounding or find another source of power for your new circuit.
Adding plugs to an existing reduced size ground wire circuit would not cause your new work to be improperly grounded. . So no violation there. . The reduced ground in the existing isn't an issue either. . If the reduced grounds were sufficient to handle the overcurrent when originally installed, I don't see that as an issue either.

Well the guy I work with was like well what if we reuse some of the wire that was there? I mean I wouldn't do it but just curious wouuld that fly or would we still have to run a new feed? Once again we are not doing that I was just curious what your answers would be?
"what if we reuse some of the wire that was there?"
What do you mean by
reuse ? . Do you mean that you're going to just leave it there and resupply it with a new HR or you're going to physically move the reduced ground Romex and reroute it ?
If you leave it and resupply power, I would consider it as remaining outside of the scope of work. . If you're going to move it, then the reduced ground is within the scope of work, is not compliant, and would have to be replaced.
This is similar to knob and tub stuff that I see quite often. . Any
undisturbed sections can remain. . But knob and tub doesn't have grounding so any extension has to follow 250.130(C) or the
extension contains a violation. . The knob and tub isn't a violation. . It was compliant at the time it was installed. . Any new would be the violation.
