Hi! I'm feeling confused around whether I need to run a ground wire to a subpanel, rather than simply grounding the subpanel where it is.
I have a 400 amp service coming into the Meter Main. I have a 200 amp subpanel 110ft away from the Main. This subpanel has two ground rods AND the feeders from the Main also has a ground wire with them.
From this 200amp panel, I am putting a 125amp panel 350ft away. I'd like to avoid the increased cost of needing to run a ground wire to it, plus I don't see the point if I add one or two ground rods at this new 125 amp panel. One of my electricians said I need a ground wire. Another said I did not. Wouldn't there be a clear-cut rule about this spelled out somewhere? Can someone help me understand why a ground wire would or would not be needed? Thank you !!
