Just wanted to double check the grounding on this install:
1200A OCPD feeding a bus style terminal cabinet. 4 buses, 3 hots and a neutral. Ground is separate in the TC, bonding jumper not being used due to the fact that it's after the breaker. So I have 4 pipes that my feeders pass through into the TC, each with a set of 500MCM AL with a 250 ground. In total, I have 4 250 MCM grounds that attach to the cabinet, and this pathway is carried through the stack via 2 1/4-20 bolts. I believe this install to be code compliant, but the fact that the 50 meters downstream share the same 1/4-20 ground path just doesn't feel right in my gut.
Opinions?
