Hello,
I have a query concerning selection of compatible meter stack. The multi-unit residential facility is fed via 3-phase, 4W, 120/208V, 400A main electrical service. Each apartment unit has a 100A, 1-phase, 3W, 120/208V electrical panel and the facility has 150A, 3-phase, 4W, 120/208V house panel. Each apartment unit as well as the facility is to be separately metered for electrical consumption.
I wanted to inquire if the best way to separately meter the apartment units and house panel, is to feed the main electrical service to a 400A, 3-phase, 120/208V meter stack, where apartment units have 100/125A, 4-Jaw, combination meter socket c/w 100A, 2-Pole breaker and a 200A, 13-Jaw, combination meter socket c/w 150A, 3-Pole breaker. The line side of the meter stack would also have a 400A, 3-phase, 4W, 120/208V main disconnect switch. OR,
Would it be best to split the 400A, 3-phase, 4W, 120/208V main electrical service via splitter box into 150A, 3-phase, 4W, 120/208V for house panel and 250A, 1-phase, 3W, 120/208V for apartment units. The 150A, 3-phase could then be metered separately via single, 7-Jaw, utility meter and the 250A, 1-phase for apartment units could be measured via meter stack with individual 100A, 4-Jaw utility meter.
I'd appreciate your comments on the above scenario.
Thank you.
