I have an existing medical facility where a contractor is inquiring whether a new panel can be fed from an existing Motor Conctrol Center (MCC). He has an existing 90/3 breaker in a MCC "bucket" that he's like to use to fed a panel adjacent to the MCC. He would remove the existing H-O-A and starter in the "bucket" and fed a new 100 amp panel. The new 100 amp panel will have (2) 20/3 breakers supplying power to (2) new HVAC units.
Would this be allowed by the NEC? Thank you for your assistance.
