110 VAC Breaker Boxes
Main Breaker Box
The 110 volt and 12 volt breaker boxes are generally located in the bathroom cabinetry. Circuit
breakers and fuses are installed to protect the electrical system from overloading. Do not attempt
to change the circuitry or add appliances yourself. Please consult an authorized Newmar Service
Center.
Inverter “Sub-panel” Breaker Box
The circuits that the inverter supplies power to are independently protected in a smaller “sub”
panel located adjacent to the main breaker box. This panel is powered by the inverter. When the
unit is plugged into shore power or the generator is running, the current passes through the
inverter to supply power to these circuits.
When there is no external AC power source, the inverter powers these circuits with the house
batteries. Note that every appliance and accessories in your unit is not on the Inverter “Sub”
Breaker box. Only those appliances in the Inverter “Sub” Box will be powered by the inverter.
Generator
The generator in your unit is located between the front frame rails, and is mounted on a hydraulic
cradle that will extend or retract the generator at the touch of a button. It is wired into the
“Automatic Transfer Switch” and will power all the 110 volt AC circuits in your King Aire. The
generator can be started from the dash switch, or remotely started at the generator itself.
Located on the generator remote start panel (at the generator) are two main breakers for the two
output legs of the generator wiring. Please note that on startup, there is a momentary delay in the
“Automatic Transfer Switch” engaging to pass the electricity on from the Genset.
The generator in your new King Aire runs on the same diesel fuel as your main engine. The diesel
fuel is drawn through a separate supply tube that is positioned in the tank in a manner that will
not allow the generator to draw fuel and run if the tank level dips below the ¼ level.
Please refer to the generator manufacturers operating guide for specific information on
maintaining your new Genset. Regular oil changes and other maintenance performed at the
prescribed intervals will greatly extend the life of your generator.
Inverter
Your King Aire is equipped with a 2800 Watt “Pure Sine Wave” inverter. An inverter changes
DC power from the house batteries into AC current to operate most of your appliances.
When 110 VAC is present from the generator or shore power, internal switching in the inverter
passes the electricity through to the appliances it controls, and turns on a charge circuit to
recharge the batteries. The inverter is controlled by the remote panel located in the front overhead
cabinet.
The ME inverter / charger has two modes of operation: “Inverter” mode (providing power to the
appliances from the house batteries), and “AC” mode (running from shore power or if your
Genset is running).
