There are four (4) electrical inlets and each one powers different parts of the trailer. There is a directory of the breakdown on the inside of the control room door (see picture attached). The breakdown and details are as follows:

Top cord – this powers the water heater (12 amps)and the blanket heater (5 amps) on the waste tank.
Middle top cord – this cord powers a room heater (7 amps) and the wall heater (7 amps) in the control room.
Middle bottom cord – this cord powers the other two room heaters (14 amps total).
Bottom cord – this cord powers the convertor for all 12v – radio, lights, fresh pump (4 amps) and the air conditioner (12.8 amps cool / 16 amps heat).
