600 HP Motor
(OP)
I have a 600HP motor that is controlled by a soft start motor. Nameplate FLA is 673A. I want to reuse an existing 1200A inverse time circuit breaker. I know the NEC says you can go up to 250% but that puts me well over the 1200A breaker I want to use. Is it reasonable to think that 178% FLA will be ok because its a soft start?

The amount of starting current will depend on what you are trying to start, to some extent.
