I'm trying to size my MC feeders (coming from the metered portion of a main switch gear) going to various utility panels at this housing complex. Its basically like a big apartment.
Also from the main switch gear there is a tap to the unmetered portion of the switch gear which goes to various meter cabinets on 4 floors of this housing unit. From the meter cabinets they branch off and pick up 100A panels in every residential unit of the building. The loads for all the panels have been figured. All I have to go by is the panel size.
So for the 3phase utility panels if its a 225A panel do I size it for 225A when fed by 4 wire 3 phase MC? Any derating factors for that?
For the residential portion where tenants will be living in those units do I size it for 100A 2 pole? Any derating for that?
This is a slam dunk easy question but I'm spacing right now as to how it goes....any help would be greatly appreciated.
