Apartment Building

[mbrooke]

How would you wire an apartment building where the land lord pays the bill? And in particular one where the select receptacles are on backup power (refrigerator, TV)? 2 panels in each flat seems extreme. Would you share any circuits between each unit?

If the landlord is paying the utility bill, it doesn't matter either way. If this is new construction hallway panels serving multiple apartments would be the most cost effective way to wire it, the EM circuits can be shared between units.
Although landlord may regret not having provisions to make tenants pay there own in future.

Unless under continuous building management supervision, 240.24(B) requires that the occupant have access to the feeder and branch circuit OCPDs that supply their unit. That makes this installing a bit more difficult where there is an optional standby system.

Correct, why all panels would need to be in Hallways, including the EM

I would be very unlikely to rent a unit with my panel in the hallway.

Wouldn't a common hallway panel be enough?

Would anyone would know the difference or care?

Its going to suck having a 600 amp panel board with 20 #3 feeders coming out of it.

Sure for the code, but not for me. I don't want others to be able to turn my circuits off and on. Also don't want to have to run out into the hallway to reset a tripped breaker.

How much does two 100A panels cost? It might cost less to run two feeders to each apartment than to have a large load center out in the hallway and run separate branch circuits. You will have to have spaces for GFCIs and AFCIs that will take up a lot of room in the load centers in the hallway.

Although my choice would be to run a feeder to each unit and install a CB panel for them and then maybe use 1 EM panel to for all of them. I think 40 feeders might be excessive but it will depend on owners intent on the Generator? will it be complete comfort for units or just maybe Frig with 1 light and 1 receptacle?

EM circuit is just the fridge, hall lights in the apartment itself and two living room receptacles for the TV.

I'll take your word on it. I've never crunched the numbers.

Beat me to it (again!) Don, but what say we give 240.21 (B)(1) a gander?

it's not rocket science. An all inclusive MDP w/dedicated 'critical loads panel', accessible to all tenants (community laundry area?) with a LOT of home runs , OR a lot of SER al home runs from a meter main(s) , oh and, subtract the 'house meter'.....~RJ~

Only one meter here... but certainly just as interesting if each unit was metered but you also needed backup power.

If i want to keep the land lord as a repeat customer I would not share any circuits between each unit (Just to keep his/ her sanity)except for smokes in required.
