we have 3 reverse cycle systems on the boat. I can only run 2 ac's at once due to current pull. We have learned to adapt to that. With the main system on heat, I seem to pullabout 6 more amps than on cool. When I turn on a second system, it kicks the inlet breaker. It doesn't kick the ac breaker but the inlet breaker.

My intakes are very clean. I've gotten good at cleaning strainers and checking hoses and the water flow is great. I don't think I have heat strips but don't know how to tell.

The really odd thing is that the main[largest] system runs fine. It is the inlet breaker connected to the smaller unit that kicks.

Any ideas?
