Generator Switch Box

The installation manual specs locked compressor inrush at 60A and locked fan motor at 6A. I don't think there's any delay built in to delay compressor startup. I believe this cause there are addons to dometics to insert delays. What are your leg voltages during compressor startup? If the genny is a weak voltage source then voltage will fall more than normal and inrush current will increase above those spec-ed in the manual. I think max inrush would occur only for the first half second or so and quickly disappear and be over within 3s (exponential decay). I have had no problems running three AC's on the genny. The manual specs a minimum generator capacity of 3.5KW per AC unit, so our 15KW units are easily adequate if operating normally.

Thanks David
I didn't realize the compressor and fan motors were not the same.
I will check the voltage during startup in generator and shore power mode.
