Sizing Molded Case Circuit breaker for this service
(OP)
Guys,
I have 3 motors (200 hp, 2 hp, 5 hp) in a service and I want to size the main circuit breaker for this service.
Articles 430.31-44 of NFPA talk about overload protection and 430.51-58 talk about short circuit protection.
If I want to size a Molded Case Circuit breaker for this service, which article applies?
