From here to there...

There was little or no actual design of the distribution system.  There would be two systems for distribution, 110 VAC and 12 VDC.  The AC power will be handled with standard breaker panels and conduit systems.  A pair of of dual breakers in the primary panel server as a transfer switch between the generator and "shore" power, coming in through the rear bumper.

The low voltage will use fuse panels from the RV world incorporating mini blade fuses.  A solid state disconnect is used between the service batteries and the inverter/DC systems.  Commander 350 DC Disconnect
