Generator
The generator supplies AC current to your coach when running. You generator is hard wired into the
“Automatic Transfer Switch”, which routes power into the breaker box and beyond to the accessories it
powers.
Inverter
The inverter is designed to invert DC power from the house batteries into AC to operate the applicable
appliances and accessories. The inverter also has a charge circuit that will recharge the house batteries
when AC is present from the shore power cord or generator.
Incoming AC Power
The incoming power from the generator or shore power cord is routed to the main breaker panel. The
source is selected by way of an “Automatic Transfer Switch”. When 110 VAC is present on the incoming
legs, the Automatic Transfer Switch will select it as the power source, and will switch automatically to it.
IMPORTANT
If power is supplied to the system by both the Genset and shore power cord, the automatic transfer switch will
select the generator input by default. By prioritizing the generator circuit, power will always be available as
long as the generator will run, regardless whether there is access to shore power. If the unit is plugged into a
shore power outlet at a campground, and the generator is started, the automatic transfer switch will default to
the generator circuit.
To connect the unit to 110 volt shore power, first make sure all of the breakers are in the off position. This
is done to avoid a power surge. Unwind the power cord from the electrical compartment. The standard
electrical service in this unit is 50 amps with a flexible cord. Check to make sure the pins in the outlet are
oriented correctly, that they match the power cable, and that they are in good condition. If there is a
circuit breaker switch at the plug, it should be turned OFF before making the connection. Insert the plug
completely into the outlet and turn the circuit breaker on. Close and lock the electrical compartment door
to keep the contents clean, dry, and secure. Close the cover on the power box, if equipped, to avoid an
unintended disconnection and to keep contents clean. Switch the main breaker to the ON position. The
120 volt system will energize all 110 volt circuits and outlets when the main breaker is turned on.
IMPORTANT
It is important to inspect the shore power cord before and after each use. If the cord or plug shows any signs
of damage, either from abrasion or heat, or if the pins are loose, or the insulation is damaged or pulled back at
all, it should be inspected by a qualified technician for potential replacement. NEVER use a shore power cord
that has exposed wires or signs of heat damage (melting insulation or cover, misaligned pins, etc.).
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.
