Its been a while since I've dove into this and I thought there were some code changes.
Does the metal racking on the roof require an GEC or is an EGC acceptable? What would be the code references?
If I run NM cable, say #10 to the roof which carries a #10 ground does that suffice for grounding and bonding of the array? I am mostly talking about non-exposed areas such as the attic or in wall cavities. Under the array on the roof I understand I need a #8 or greater (or is it #6 and greater?).
Thanks ahead of time
