On the secondary side of a transformer the ground ran to the panel, is it sized according to the equipment grounding conductor or a grounding electrode?? (bonded in transformer)
I have a 400A main, I could have ran parralell 3/0 but since I had 4/0 on site that is what we used. I ran parralell #4 that would be good for the 3/0 required but since I used 4/0 do I have to up my ground also?
Would I be able to use the #4 if I bonded in the panel?
thanks for any help
