I have a project where the modular meter center will have single phase meter/breakers for the apartment units and three phase meter/breakers for the house & retail spaces.

My question is... Is the combination shown in the picture below available or do I need to reconfigure some of the meter/breakers?
(E.g., should the "blue" retail panel & meter/breaker be changed to single phase? or should it move to the left side of the switch box? or is it fine as is?)

Please see picture here:

I have designed that set up before. Yes, that is an available set up. I believe that both sides of the meter main will be 3 phase out and the bussing on the single phase side will be designed as to balance the load across all three phases. Get with a gear rep in your area and they can help you out with this.

The only thing I would point out is that you can't mix 3Ø and 1Ø outputs in the same vertical section, so that retail feeder at the top right can't be in a section with resi meters.
