We are designing the power feed to a small control panel. It is a skid mounted pumping system that includes 2 small pumps and the control panel all pre-wired. The control panel has an integral non-fused disconnect (30A-3P). The manufacturer indicates the full load amps are 5A at 480V-3phase. We asked them for the recommended overcurrent protection device (feeder breaker). They indicated to size per the NEC which always seems to be the easy way out for a manufacturer. This would most likely be considered an industrial control panel where 409.21.C would be the rating of the breaker. However, it appears you can't go by FLA of the panel, but need individual load ratings. Not sure where to go to calculate the proper breaker size.
