Do you leave your galley fridge on AC power when leaving the boat (circuit breaker on AC side and OFF on DC side) when you leave the boat for the week or switch it over to DC? We keep bottles of water and drinks in the galley fridge and since it’s dual power, not sure what’s the best practice.
The manual says the following :”Since the refrigerator is dual voltage (12 and 120) make sure the DC refrigerator breaker is activated and the AC refrigerator breaker is deactivated upon leaving the vessel.”
But I am wondering if that’s more load on the house battery than necessary and since I am plugged into shore power, I should use the AC power side for keeping the fridge cool weekend to weekend.....
thoughts?

In our case we leave both AC and DC breakers on, in the case you loose shore AC power the house battery will take over and not loose a bunch of food or cold beers.With our fridge the AC continues to power the fridge and if you loose AC power the DC house battery takes over so not much to loose to keep both breakers on, what size is your house battery? Also, if your on shore power and fridge is only on DC the house battery charger will have to keep feeding the house battery power to keep fridge running on DC but I would rather have the shore power AC run the fridge directly and not tax the house battery charger as it also is keeping the propulsion engines starting batteries etc fully charged.!

House battery is a group 27 battery. The battery charger breaker stays on when I leave the boat and shore power is plugged in. I do the same thing as you, as I’m leaving both breakers (ac and dc) on for the fridge. Not sure why regal recommends in the manual to leave it only on dc when leaving the boat. Hence my question. |

With my 4460, I always left the AC and DC sides for both of my Fridges on with that boat. I also left the battery charger on obviously. My thinking was that if they had to turn dock power off, or if the power was down for a while, at least the both fridges would have battery power until that was gone. Power normally never stayed off long enough to have the fridges drain the  . With my 33 OBX, I again have two Fridges and while I have a switch on the panel for electric to the fridges, i've tested them and they do not run on electric at all. I left that electric panel switch on, and turned the house battery switch off and both fridges went off with the battery switch. The end result is the same though as with the 4460 since the fridge run on battery if power falls away and the battery charger is down for a while the fridges will run until the batteries are drained. The good this is with the 33 OBX, I actually have 3 house batteries, two stock Group 31s I think, and an additional 8-D I added. So plenty of battery to run the two fridges for a while. |
