    Since owning my 440EB (5+ years now) I've always been at a marina or dock that had both a 120VAC 50A and 120VAC 30A shore power connections and never had to deal with my current situation.

    Not sure if it is just the 440EB, but I have a 120VAC 50A that powers the main salon a/c, battery charger, house lights, outlets, stove and a few other minor systems. I then have a 30A that powers the front cabin a/c, hot water heater, stereo, tv and microwave.

    I am now at a marina that only offers a single 50A connection on the dock and the things that matter most to me when onboard (i.e. hot water, washer/dryer, tv, v-berth air conditioning) are all not powered.

    In my last boat, my electrical panel had a "parallel" breaker where I could power Bus B with power from Bus A. It just required that I thought about what was being used and the occasional girlfriend with a hair dryer with the a/c running and a few other things caused me to blow a breaker.

    The 440EB does not have that ability.

    So, unless I have both a 50 and 30 dockside, a lot of my boat is not powered.

    I can't think of a time where I would be using close to 50amps.. Even with both air conditioners running, the hot water heater, cooking dinner and misc systems running, other than the starting surge of the a/c units, I am under 40amps, even with the microwave or stovetop, under 50amps.

    What do other 440EB owners do when they get to a marina that only offers single 50A service? or is my boat different from other 440EBs?

    I think that I may be able to make a custom pigtail, 50A in, and 50 & 30 out. Or buy a series of adapters to get both powered. I also may be able to wire the 30A bus directly into the 50A bus, eliminating the 30A shore power connection all together. But that scares me.

    Any thoughts / experiences with the same issue?

    With a lot more cruising on the schedule this coming year, I am thinking that I may encounter this more often and looking for the best solution.

    I have 2 30A ones and whenever I get to a marina that only offers a single 50A I use a splitter with 2 30A females. Sounds to me that you could do the same, plus an adapter to one side if they don’t make a splitter with one of each. I can’t imagine a whole boat taking more than 50A. I replaced all bulbs in mine for LEDs and that cut around 10A If everything is on. I have a 380DA.

    The 440EB is power hungry.. Two a/c units, two ice makers, hot water heater, microwave, washer/dryer, convection oven, inductive stove top and then lights and other little stuff.

    I know if I pay attention, I can managed to always stay under 50Amps, it just requires some thought... No cooking dinner, running both air units and doing laundry at the same time.

    Just interested in what other 440EB owners have done.. With 160+ hulls out there, I can't be the only one thinking about this.
