The load calculations should have already carried 125% for continuous loads.
That being the case a calculated load of 600 amps could be supplied from a 600 amp panel.

Sure, you could buy a switchboard, or you can build your own 600 amp service with wireways to separate panels. Your choice.

In my area at 600 amps I am pretty sure it would be CT metering so seeing if a panel shop could make up a 600 amp CT cabinet with three 200 amp service disconnects might be worth while.
I do not know if this could be found off the shelf.

I've never really found a cost effective way to build a 400-1200 amp resi service other than using multiple 200 amp panels.
not sure if I understand how this is done any photos? TIASure, you could buy a switchboard, or you can build your own 600 amp service with wireways to separate panels. Your choice.

CT cabinet ----> 600 amp disconnect----->gutter-----.3 -200 amp panels under it.

How about CT cabinet ----->gutter----->3 -200 amp main breaker panels grouped in one location?
ok so this would also be the best even if I needed to put 200 amp panels in different locations

Duh! I wasn't seeing the forest for the trees. Assuming main breaker panels, yeah, you're right.
My only concern would be the length of the service conductors inside, hence the disconnect. Without knowing the details it's hard to say.

No! Save the cost of the 600 amp disco. If your panels are grouped, use 200 amp MB panels. If the panels are distributed, use grouped 200a discos and use them to feed MLO panels.

It could be tricky trying to use this arraignment
and locating the panel away from the disconnect, you would have to comply with the tap rules.

I would listen to Marc, he has far more experience with this then I do, both pricing wise and planing wise.
no doubt the (3) 200 amp panels would be the economic plan, but with a 551 amp load, getting the diversity correct betwween the 3 panels is going to be a real trick. You might save yiurself a headache to add a 4th panel up front.

Ya, sometimes you're forced into using one. Cramped quarters, for instance, where you can't get them all reasonably grouped in a short distance. Apartment buildings are another, where you might only have a 600 amp service, but 12 tenant disconnects.
