I am expiriencing problems with running the heat pump and water heater at the same time. When the heat pump kicks in it blows the shore power (main breaker). Any suggestions from someone who has expirience the same issue?

Hunter says....
April 14, 2004 Dear Hunter Owners, Over the last few weeks it has been brought to our attention that many Hunter owners are not using the proper amperage and voltage required for boats with factory-installed heat and air-conditioning. It is outlined in the Hunter Owners manual for all boats to use two (2) thirty-amp services if either the heat or air-conditioning is being operated on the vessel. At no time should splitters or pigtails be used in conjunction with power cords to service a boat. Any boat leaving Hunter will require, no less than, one-hundred twenty volts and thirty amps of service for each dockside inlet on the boat. Failure to provide this type of service can and will cause system failures. It is not uncommon for short cycling of the units or tripping of the main circuit breakers to occur when low voltage or amperage is delivered to the boat. For many years it has been common for owners to use a single fifty amp service with a splitter/pigtail. With today’s new overhead ducting systems, such as in the H41, proper amperage and voltage to the boat is a necessity. For owners who are not familiar with this requirement a review of their boats owner’s manual will be of help. For H41 owners you should refer to page 63A -2 in your manual. Thank you The Customer Service Department

Simply too much power draw
Your heat pump (I presume this is a reverse-cycle A/C) probably draws 8-12 amps when running and twice that to start. Your water heater is about 8-10 amps. The shore power breaker is typically 30 amps but could be only 20 amps. You might be able to turn on the water heater AFTER the heat pump is running, but the breaker would trip at the next heat pump cycle due to the heavy starting current. The fix is to install a separate shore power connection for just the heat pump. Then you would need TWO 30 amp connections and cords. Sorry, probably what you didn't want to hear....
