Shorepower: 50A to dual 30A

Postby shade2u2 » Mon Jun 18, 2018 4:07 pm

My new to me boat has dual 30A shorepower with individual HVAC units on each 30A circuit. I have to plug in to a single 50A shorepower pole.
I assume that the best way to connect would be a 50A cord leading to a adapter splitting to dual 30A for plugging in the boat. Would this be the safest with the least loss of juice?
It would be expensive as I don't have any 50A cords.

I have a single 50A to single 30A adapter and a 30A to dual 30A splitter two 50ft 30A cords. With that, would it be okay to plug in as follows:
50A pole + 50A to 30A adapter + dual 30A splitter + to two 30A 50ft cords then plugged into my boat?

I imagine that this would be better than a singel 30A 50ft cord leading to the 30A splitter at the boat.

Buy a 50 amp to two 30 amp splitter. Then run your two 30 amp cords to boat. If you don't need 50' of cord and can get by with two 25' cords then buy two 25' 30 amp cords as well to clean things up. Lastly understand that you will be limited to 50 amps regardless.

I have a 50', one 35', and a couple of 25' 30 amp cords.
Last night I hooked it up like this:
50A pole, then 50A to 30A adapter, then dual 30A splitter, then one 30A 50ft cord AND one 30A 35ft cord plugged into my boat.
I will keep and eye on it and try to see what my amps are or if anything overheats.
I may look into one 35' 50amp cord as that is the length that I would need for my dock.
thanx
