    Main Circuit Breaker-gctid801567

    1999 2655 Ciera. Any idea where I can find a replacement main breaker. The 220v is broken in the center and it's a real pain to coordinate setting both 110's at the same time.

      That's not a 220V circuit breaker. It is a double pole circuit breaker. The reason it is a double is that the rules require breakers on the hot and neutral main lines coming to the boat. The rest of your AC breakers are single pole, connected only to the hot line.

      If you are in the Seattle area, you may want to go to Fisheries Supply. They are also online as builderdude showed. If you are in the north Puget Sound, try Harbor Marine, in Everett.

      BTW, you may want to add your location to your signature or profile.

        Nice information. Does the shore cord bring 2 phases to the boat? I always thought we had 220 capability. Go figure.

          I'm betting I'm going to say this incorrectly, but, your shore power cord is single phase 120 volt power only. The cord is so large partly to keep anything short of a guillotine from damaging the three (black, white, green) wires.

            Whether 120 or 220, you will be operating on single phase current, so there is no concern for single -vs- three phase regarding your main circuit breaker.

            Circuit Breakers protect against circuit over-loads via a pre-set AMP value......... not voltage values.

            If your boat is set up for shore power, you will see either L1 or L2 being used for 120 vac, plus a Neutral and Earth Ground...... or both L1 and L2 for 220 vac plus the Earth Ground.

            The same double pole breaker is used for either 120 vac or 220 vac

            For 120 vac, L1 or L2 is on one pole, and the Neutral is on the other pole.

            For 220 vac, L1 is on one pole and L2 will be on the other pole.

              I'll pull the panel cover and have a better understanding, but do marina systems provide 220 to the shore cord plug? It sure looks like the breakers are 220V. If so, the 220 runs to the boat breaker panel and uses the neutral and ground as one.

                Much of the power system used on boats looks like more voltage that it is. Marinas in North America tend to have 120v in various amperage. Europe is probably 240v because that's the prevalent voltage for most appliances.

                Look carefully at the flat face of your plug, either end. You should see markings that identify voltage and amperage. 15 amp looks like a normal three pronged household device. Above that they are insert and twist to lock of varying male and mating female diameters for 20, 30, and 50 amps. There are some marinas that have 220v in their 50 amp system to meet the needs of larger boats with air conditioning or laundry dryer, but much of the time the cable is plugged into a splitter that's connected to two 30 amp 120v circuits as would be the case on my boat.

                If you own a mega yacht then you might get into huge power draws that require special Marina circuitry and fire hose size cables. Of course the crew would actually take care of this for you..... :lol:

                  I agree with P/C Pete. In my case I had a splitter that hooked to the 50 amp hook up at the power station on the dock and fed two 30 amp cables that hooked up to to two 30 amp inlets on the boat. Since I live on board I do use a lot of electric power. It got to the point that I was using to much power and my black wire going to the L1 main breaker was getting very hot. I put in a third panel and used a third 30 amp cable. Now my power lode is spread over panels L1, L2 and L3. This has solved my problem. I am sure there are other ways this problem could have been solved. But this setup works for me.

                    Your boat is wired for 110 VAC and most marinas provide this. The main breaker at your boat will be a double pole breaker. Also, the breakers at many marina power posts are also double pole. This is why it looks to you as a 220 outlet.

                    Here is some good information:

                      This will be somewhat redundant to what has already been posted.... just perhaps a different way of explaing it:

                      110 vac is a result of L1 or L2 (not both) and one neutral.

                      220 vac is a result of L1 and L2, no neutral required.

                      110 vac at dock side Outlet fitting will include L1 or L2 (not both), 1 Neutral and 1 Earth Ground.

                      110 vac at the vessel Inlet fitting will include the same.

                      One prong will supply the Hot (L1 or L2), one prong will suply the Neutral, and the prong with the hook brings in the Earth Ground.

                      220 vac at dock side Outlet fitting will include both L1 and L2, 1 Neutral (so that L1/L2 can be split off into 110 circuits), and 1 Earth Ground

                      220 vac at the vessel Inlet fitting will include the same.

                        Your "One prong will supply the Hot (L1 or L2), , one prong will supply the Neutral, and the prong with the hook brings in the Earth Ground" hit home. Thanks so much. My shore cord brings only L1, a neutral and a ground. Why have a double pole main breaker? Are we monitoring/protecting over currents on the hot and neutral legs? Seems silly (unless it is a GDIC).
