    The NEC has nameplate rating requirements for motors, motor controllers and such, but does not seem to address this.  Arc flash calculations would take into account a motor acting like a generator during coast-down following an interrupted fault.  Thanks for any guidance you can offer.

    Sorry but though we do our best to answer questions here, we are a general questions and answer site only and this is beyond our knowledge base. I'm not even sure where to direct you for help. I apologize that we could not be of any help.
