Kingfisher is wired differently than previous boats I've had experience with.
When I wired my sailboat years ago, I installed a transfer switch so that AC power could be supplied by the shore connection or the inverter, but not by both.
Kingfisher has no transfer switch. Instead, the shore power goes directly to a small AC panel which feeds the hot water heater and the AC/DC refrigerator. It then feeds to the Xantrex charger/inverter before being distributed to the 110v outlets throughout the vessel.
In other words, all the 110v outlets aboard are actually supplied by the inverter rather than being fed directly by the shore power connection. As a result, we trip the inverter's breakers (2,500 watt rating) in the winter time if we plug in two space heaters.
I would like to be able to have more capacity for dockside power during the winter months, such as an engine room heater plus a cabin heater or two. It doesn't give me confidence knowing that the relatively low-power rated breaker might trip when I'm away from the boat during extremely cold weather.
Thoughts?
