So I looked at a job today and need some help I lack a bit in this portion of the code
The building is 70 units
14 stories with 3 floors containg meter banks
The meter banks are fed with 400a 3 phase.
Each 400a meter bank feds 23 apartments with 60a mains
The reason I was called in is because the building wants to get rid of the gas lines and install Electric ovens 40a each
Each appointment currently has an electric hot water heater and Electric stackable washer and dryer both fed via 2 pole 30 amp breakers.
I'm pretty sure I need to upgrade the feds and panels in each apartment.
My concern is the 400a feeding the meter banks is not adequate. I know it should definitely be engineered but maybe some one here can help me figure out off the bat if it's big enough, if it may be obviously to small or close to adequate where an engineer is needed
