The reason he wrote it up is that this mounting does not provide "direct metal contact."
He also doesn't like the EMT fittings without a grounding bushing or a Meyers Hub.
He says that the hole (7/8", 1-1/8", etc) is larger than the fitting, and thus does not provide "direct metal contact"
I looked up "direct metal contact"
in the '99 NEC for a total of 0 hits for my query.
The secondary conductors from the utility transformer were not yet installed, so when I gave him a torque letter from the office that the gear had been torqued to specs, he told me I was committing FRAUD.
This & more was all before I told him he was crazy.
He's an older fellow not by the beach, Randy.
