Trying to get this clear in my head. I know that 250.122c says you can run one eq. ground for multiple circuits in the same conduit as long as it is sized for the largest overcurrent device, my question is:
Question 1--Is there a limit to the number of circuits, as I'am putting in a new service at a home and I have to move it to the end of the house.So I have 7-20 amp sp 120 volt circuits and 2- 30 amp 2 pole circuits is it o.k. to run just one #10 for the eq. ground? And just tie them all together under one split bolt or ground bar at the junction box that is located where the old service was?
I read it as yes,but need some backup to make sure this is right.
Question 2-- I have an inspector who does not know the code well and he always falls back on ("Well we like to see it that way") When I know that it is legal. Should he have to show me it in writing or should I just not bother and do what he says, sometimes I end up making another trip because of him. By the way he is my neighbor and we've know each other for 15 years before he was an inspector and I was a contractor. This ties into 250.122c because I know he will question me on this eq. ground for the service change.
Thank you in advance for any input.
