Tom,

That would depend on two things not shown:
1) What size where those service entrance conductors? Copper, but what size/rating?
2) What was the rating of that equipment which was shown on its label?

The lesser of those two would be the rating.

Visually, the comparative size of the service entrance conductors are larger than the feeder conductors coming off the right 200 amp main, thus the service entrance conductor *might* be rated for 400 amps, but is the equipment rated for 400 amps (probably)? If so, then the service size would be 400 amps.

The left main feeds the panelboard below it and feeds through that panelboard to another panel someplace else.

The right main feeds another panel someplace else.

Thus you have 2 200 main disconnects (service disconnects) and 3 panels, 1 of which is 'part of' the service equipment.

The other panels would need to be rated for 200 amps minimum.
