Thanks for the input.
Let me paraphrase ITO:
800A main disconnect.
Tap box/tap block
gutter
House meter
277/480V house panel
10KVA 1 ph xformer
120/240 1ph house panel (I think the only thing that may be on this is a heater for the water service hot box).
My local utility requires a disconnect ahead of a 480V meter. But this building is not local for me (it is NiMo I think).
What 100A (or 200A) 480V meter will give a short circuit rating above 10K?
What am I missing?
