2015 R31-CB Generator Usage

[JeffreyAC77]

I am a new owner of this boat (2 months). It is currently docked with shore power. I would like to test usage of the generator and am not sure of the procedure/sequence to start the generator. I assume the first step is to disconnect shore power. The only thing I have running on shore power is the refrigerator and ice maker.

Once the generator starts, then I plan to turn on what I want to power (not leaving the dock).

Is there anything i must turn on to operate/start the generator properly?

Am I missing anything here?

thanks,

Breakers off, disconnect the shore power, start generator let it warm up, switch from shore power to generator you should get a green indicator light then turn on 30 Amp breaker and then load up with what ever you are planning to run by turning the individual breakers on

Turn the 30 amp shore power back on after generator is running? Why is that?

thanks,

You should see a selector switch that says shore/generator/inverter. After warmup switch selector to generator. The 30 amp breaker being turned back on is to turn that panel back on no matter what source (shore or generator) you choose.

Check out this youtube video on ranger tug power management. You might find it helpful.
Also look at page 15 ofthe user manual. Selector looks like it is on the bottom. Manual is on this site under forum index the technical bulletins.

I believe he is referring to the Main AC distribution panel 30 amp breaker. None of the AC panel breakers will get power until the panel itself gets power. So start Genset, then start extending power into the rest of the boat: AC Selector switch, then AC Panel Switch, then finally AC Panel individual breakers to the device you want to run. Then when you are done, reverse the procedure just to be on the safe side. I've adjusted my thinking to turning a single appliance on/off (i.e. microwave) via multiple switches unlike at home where its usually just one switch. Its a bit of a pain, but I believe safer and helps reinforce the electrical layout in your mind for future work or troubleshooting. GF

The power management video cited by Matty is an excellent resource. It will help you learn power management on your boat. I don't remember the capacity of the gennie on the R31's. Let's say it's 3500 watts. Divide by 120 volts and you get around 29 amps. That continuous. Your appliances, particularly the heat pumps, will have a start up surge load that is higher than the rated running capacity. That's why you turn things on one at a time. You may not be able to run everything at once. Same skill set will apply to using your inverter. Learning this at the dock is a smart move.
