Sub-metering over 1000 dwelling units

[infinity]

By the way how many amps in this day in age should an apartment have regardless of what article 220 says? A lot of NYC apartments are 120/208V split phase 60A apartments which in my opinion is waaaay to low. Do you think it's practical to have 100A minimum?

A majority of the apartments that we build (1, 2, bedroom) have 1Ø, 120/208 volt, 100 amp feeders. 3 or 4 bedroom may jump up to 150 amps. When you get into high end condos that can increase to 200 amps or even 3Ø.
