Bonding XFMR GEC to rebar for ungrounded system

[ActionDave]

Transformer secondary only needs a GEC to the building steel.

But the indoor panel would be bonded to the building steel as well.

Yes, but no ground rod needed.

The ground rod for the service entrance, connected to the panel. Meter base etc.

Well it would depend on which electrodes are available. If it has a CEE, no rods would be needed. Yes of course rods are usually the go to electrodes if something needs to be installed like in an existing building where there is no UFER

Right. I land a rod anyway. Can't hurt.

That's like giving a dead man an enema. No harm done, doesn't accomplish much though.

You gotta understand I work in areas where the fire dept does electrical inspections. When they don't see a ground rod they flag it. They don't know anything about CEE/UFER, and my customer isn't getting their occupancy permit.... it's better to give them what they want rather than arguing NEC with a fire chief. Just sayin that if anyone else out there deals with this like I do...

Our POCOs require a rod at the meter regardless of any other grounding

Yup. That's the case in Missouri. PEX water main = 2 ground rods in some counties.

That's what the NEC requires if there's no CEE, but not if there is one.
