Add shorepower connection for ac installation?-gctid397615

[Guest Close Guest]

Hope everyone is having a great boating season as we are here in Chicago! 100 degree heatwave continues..... I cannot take the night temps anylonger , we have the hatch ac and just isnt cutting it, So im ordering the real permanent solution and will do most of the install while in water and pull out to do the thru hulls, however my question is i have noticed similar boats to mine with ac that have 2 shore power supply . i have a breaker left on my existing panel for the ac but do i need an added shorepower supply? iif i do not add will i run the risk of overloading the existing situation ? breakers blowing? fire?!

From my point of view since your limited to 30 amps at the dockside receptacle anyways there's no reason not to put the air conditioning on your existing panel and inlet you just need to manage your power use.

I ran a 6500 BTU AC unit for 10 years on a single shore power cord on my 2655

Although I can, I've never run two cords.

On my new (to me) 2855 It has two set up for cords. I still use just one. I just don't turn everything on at once

Same here,and on my old 2655 the PO had it connected so as only to use one plug. Ran fine and could use microwave at same time,just wouldn't try water heater.

Agree. Your risk is in accidentally over-loading the entire system. If the Main Breaker is doing it's job, it will trip.

I have only one 30 Amp shore power connection and I have AC on my boat (1997 2855) It appears to have been added post-factory. I have had no trouble with this setup.
