This free MPOM tool sizes your genset properly: enter total load in Quick mode, or list each load in Detailed mode \u2014 which accounts for motor starting current, the factor most sizing mistakes ignore. Why motor starting loads matter Direct-on-line motors (pumps, compressors, AC units) draw up to three times their running current at start. A generator sized on running load alone may fail to start your largest motor. The Detailed mode therefore sizes for the worst case: all loads running, largest motor starting last.

Why motor starting loads matter Direct-on-line motors (pumps, compressors, AC units) draw up to three times their running current at start. A generator sized on running load alone may fail to start your largest motor. The Detailed mode therefore sizes for the worst case: all loads running, largest motor starting last.
