    Dual shore power plugs 32xx-gctid378583

    Most boats I notice with 30A shore power have a single plug into the boat's system. Mine has 2, and there are 2 main breakers on the AC panel. Why would that be? It seems to me that 30A at the shore outlet = 30A at the AC panel, what is the purpose of dividing the supply into 2 circuits?

    I would think it would be for the AC... I have 1 30 amp on my boat and going to add #2, 30 amp just for the AC....

    Just my thinking on it.....

      Factory A/C had two inputs.

        It means that you could have 60 amps to the boat...mainly necessary when the boat is prewired for A/C.

        I have similar on my 3587 and have 2x30 amp cords to the boat.

          Just to avoid possible confusion - the AC or A/C referred to in the responses is Air Conditioning, as opposed to the AC for Alternating Current in the original post

            On my 38, one input supplies power to the aft part of the boat and the other input supplies power to the fore part of the boat. I use a splitter pigtail to connect the single 30A power cord to the two inputs.

              I do what Cannonball does. By having a splitter, I only need one 30 amp service. It is possible to overload the cuircuits this way. If ran A/C, Stove, Water heater and something that draws a fair ammount of current of a recepticle, you could overload a single 30 amp line. Just don't run em all at the same time and you'll be fine.

                  Some marinas, like where I'm at now, have two 30A outlets for each slip, so you'd run two 30A cords to your boat. I also have two inlets, one feeds the aft A/C and the other the FWD. Down here it's good to have two A/C's.

                    +1 on the splitter. I used to wrestle with two cords and it was a pos. Plus my moorage only had one plug in per, so I was constantly having to find a spare from an empty slip. With the splitter I have found inner peace.

                      Bodie, my 1987 3218 is wired just like yours. No AC ever on the boat. I don't know why they did this but it was really

                      nice when I wired my inverter, I dedicated one of those circuits for the inverter so there is no way someone can turn

                      the wrong thing on and drain the batteries.

                        Having two 30 amps inlets gives you the possibility of connecting two 30 amp cables to two 30 amps outlets and drawing 60 amps without overheating. By using a splitter you can sometimes draw 60 amps on one cable which is supposed to hold a 30 amp load only thus a lot of heat on the cable and the outlet and voltage loss. When on one cable you have to avoid running two A/C, the water heater, the battery charger and the hot plate together. limit the power draw to 3500 watts.
