for a multi tenant commercial building when should a power meter center be used in lieu of a switchboard? Also, does NEC limit how many utility meters or feeders that can feed a space? For example using a single tenant:
(1) 1000A 208Y/120V, 3-phase, 4W MLO service with (1) utility meter that has (6) 400A circuit breakers to a single tenant space
or
(1) 1000A 208Y/120V, 3-phase, 4W 1000A MCB service with (12) utility meters that feeds (12) 200A circuit breakers to a single tenant space
