ELECTRICAL SYSTEMS
General Information
There are two electrical systems in your coach. They are the 12 volt DC system and the 120 volt AC system. Most
standard appliances require 120 volt electricity while the majority of the lighting used in recreation vehicles is
powered by 12 volt electricity. The power for the 12 volt system is supplied by the coach batteries, which are
charged by two 45 amp power converters. The power for the 120 volt systems is supplied by the power cord when
the unit is connected to an outside power source or by the generator. If installed, the optional inverter can also
supply 120 volt power. It will transform 12 volt electricity from the batteries into 120 volt power for basic
appliances.
CAUTION
Failure to turn off the 120 volt appliances when starting or stopping the generator may damage the transfer switch
and/or electrical appliances.
WARNING
Use of “Adapter” cords with the RV shore power cord.
All Newmar units are manufactured with either a 30 or 50 amp electrical breaker box and electrical system. A unit with
a shore power cord that has 3 prongs on it has 30 amp service; if the shore power cord has 4 prongs, it has 50 amp
service. To provide the correct amperage into the RV and to assure the operation is as designed, it is important that
they be plugged into the correct type of properly grounded receptacle. The receptacle
MUST
be properly grounded to
insure safe, proper operation of all electrical components.
NEWMAR CORPORATION DOES NOT RECOMMEND USE OF “ADAPTER”, “CHEATER”, OR “DOG BONE”
STYLE CONNECTORS THAT WILL MODIFY THE EXISTING SHORE POWER CORD TO A DIFFERENT STYLE OF
OUTLET. USE OF THIS TYPE OF ADAPTER WILL GREATLY REDUCE THE AMOUNT OF AVAILABLE CURRENT
IN THE UNIT, AS WELL AS CREATE THE POTENTIAL FOR ELECTRICAL FAILURE AND / OR FIRE. NEWMAR
CORPORATION CANNOT ASSUME LIABILITY FOR FAILURES OCCURING TO THE RV, ITS ELECTRICAL
SYSTEM, OR ANY OF ITS COMPONENTS FROM THE USE OF ANY ELECTRICAL ADAPTER.
To connect the unit to 120 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 120 volt circuits and outlets when the main
breaker is turned on.
Breaker Boxes
The 120 volt and 12 volt breaker boxes are generally located in the overhead cabinet on the rear bedroom wall.
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.
