When the 110-volt system is not operating, the refrigerator operates on 12 volts. When an AC source is supplied, by a generator or by dockside power, the refrigerator automatically switches to 11 0-volt. The refrigerator is the heaviest continuous draw on the 12-volt DC system. If no other 12-volt accessories are used, the refrigerator can draw ...
