The Power Distribution Box is the central electrical distribution/connection system to which all power is supplied and then distributed.

The unit houses the thermal circuit breakers which protect the indoor and outdoor receptacles, the battery charger and the CHEB unit. It also houses the microprocessor responsible for the control of the Compressor/ Heater/ Evaporator/ Blower unit.

When purchased with the shore power option, the Power Distribution Box will also house the Automatic Transfer Switch used to transfer input power from APU source to Shore Power source.

Power distribution box is installed in the truck's sleeper, beneath the bed.
