Re: Boxes mounted under bench seat - can you identify please
The outlets only work when you plug in to shore power. That circuit breaker controls the power to the outlets. One of the silver boxes (the one with the vents) looks like a power converter. If it is, then it should be plugged into an outlet neaby. When you are plugged into shore power, that convertor charges your house batteries.
