I'm on a job where a hotel is being converted into an assisted living home. On the plans the engineer calls for 2 225 amp panels to come off one 2.5" run with 4/O from the switchgear. The 4/0 will terminate to a 225 breaker in the switchgear. He has it drawn that taps are made for each panel with a 225 main.
Is this common, it's the first time I've seen it drawn like this. Are there any restrictions by doing it this way?
