Recently, an inspector wanted to turn us down for incorrectly bonding metal service conduits. We ran a 3/0 bare copper through the grounding bushing lugs of 8 conduits, then landed the ground wire. Inspector said that 250.102(C) requires each conduit to be bonded independently, not daisy-chained. If they are to be daisy-chined, then the ground wire must be increased to equal the sum of all of the conduits. Sounds crazy and I can't get that out of the text. Has anyone else run into an inspector with similar views?
