Fire Pump and 695.4

[Coachmike]

We have a new 75HP fire pump with FLC @ 96A. The service feeder is sized @ 120a.
Per 695.4 the OCPD (fuses) would be sized at 600 A.
So we need a 600A fused disconnect on a circuit of 1/0 AWG?

That's typically how it's done. An oversized disconnect and fuses with small conductors.

Cool thanks.
And I can feed through a 200A in series meter?

Must be a short service/feeder with 695.7 in mind.

And with a 200 amp meter, even the utility transformer and their conductors from the transformer to the meter might be an issue for that section.
