We have a 1200A in or plant, but I know they do make a 4000A. I
don't know the biggest for sure though.

Geezzzzzz as if that aint enough power!!!! I'd hate to have to pay that
electric bill. And imagine the size of that transformer feeding it.
The biggest listed on that Westinghouse site was 4000 (for low voltage,
meaning 240/120 or three phase 208. I know some buildings have 440 too,
I'm not sure just why, I suppose some motors run on 440, or they split
it into two 220/240 circuits like they do with 240 to 120.

All of our machines run on 440V 3ph. Keeps the wire size down.

I live it when a visitor says "wow, this is a big place, you must make
tons of money". They go into shock when I tell them the electric bill
last month was $30,000, the gas bill was $20,000 but goes up when we
turn the heat on.

Ed, what is the nature of this place you refer to? Just curious.
