1971 53MY Shore Power Hook Up

[caryboat]

Have some power questions . Just launched the refurbished 53 . We have all books and plans but cant figure out some power items..

1) We have a cablemaster in bow locker. Hooked up 50 and got a red light on the PORT 220 panel but unclear how to get that panel turned into 110. Do I need to coonect another 50 or 30 on the port or stbd side.. THe meter shows no volts- just light on

I am currently using one of the 30 amps for power but cant run everyone to test

Does anyone have a standard power plan and what switches should be on what?

1) At the dock set up of a/c's etc What is the easiest switch configuration to get max power. I also have a smart box if need?

Thanks

Not clear what shore power you are connected to? Sounds like you have 110volts only?

You should be able to power the entire boat with the one 50A cord. Not sure what your set up is but most likely you'll have to manage the load with just one cord. Not familiar with the electric on that boat but you should have a selector switch for each service panel to choose which source energizes it. Whatever source number your Cablemaster is should be the same for all panels. You don't do anything to step down the voltage, it's done in the distribution panels. If your not seeing voltage on the meter it's most likely because the meter has a selector switch. Some are also momentary so you need to hold a switch to get your reading. Hope this makes sense and helps.

Look at your electric distribution panel (or post a picture of it. The red light indicates you have 220V power incoming, which is two 110V AC lines. The panel usually has selector switches for the main circuits to choose where that circuit gets its power. First, turn off all the serious consumers, like A/C, etc. Then, find the switch for each main 110V circuit on the panel (maybe only 2 main circuits in the boat if it is like mine) and move the selector switch to get power from whichever power supply that has the 220V power. It will not run 220V power to your 110V circuits. It just uses one of the two hot 110V lines. If you have 2 main 110V circuits, do that for both and the switch will use one of the 110V hots for one circuit and the 2nd one for the other circuit so your loads can be more balanced.
