Bonding Location

[Treyhagg]

So I’ve got one I’m kind of at a loss for. Our local co-op has started using a meter base with 200A breakers built in to the base itself. My question is, would that be considered the first means of disconnect for the sake of bonding? Also, for context, we did a 320 can with parallel lugs for both legs of the hots and neutrals, but it only had a singular grounding lug so it made me question where the right place to bond would be and if I’m required to pull a ground to the meter in that instance.

Are you saying you fed one panel from both breakers ??

 

[Treyhagg]

No, I was feeding two separate transfer switches, and I misspoke, it was one lug for each leg of the hots, 4 in all, but two lugs for the neutrals and one singular ground lug

Some POCOs, most of ours included, want you to land the GEC in the meter base. Therefore, you only need one lug in there.
If you're talking about the EGC running from the panel that is part of the meter base assembly, to other panels, there should be a lug for each EGC.

And we're prohibited from doing so. I think it's the best place, just before it enters the house.

Last I heard it wasn't allowed in my area (Roanoke va.) either.

If your meter is on the supply side of the service disconnects, and if by 'ground' you mean an Equipment Grounding Conductor, then no, it is not required and actually prohibited there. Table 250.122 cannot be applied because you have no overcurrent devices yet. You bond in the service disconnects. As other have said, the grounding electrode conductor can be landed in the meter if the utility and local AHJ don't mind.

Yes.

The meter has built in 200a overcurrent devices built into it
