ELECTRICAL FEATURES
GENERAL INFORMATION
There are two electrical systems in your coach. They are the 12 volt DC system and the 110 volt AC
system. Most standard appliances require 110 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 the charge circuit in the inverter, or the engine alternator while in
transit. The power for the 110 volt systems is supplied by the power cord when the unit is connected to an
outside power source or by the generator. The inverter can also supply 110 volt power. It will transform
12 volt “DC” (Direct Current) electricity from the batteries into 110 volt AC (“Alternating Current”)
power for basic appliances and accessories.
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 receptacle.
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 CREATES THE POTENTIAL FOR ELECTRICAL
FAILURE AND / OR FIRE. NEWMAR CORPORATION CANNOT ASSUME LIABILITY FOR FAILURES
OCCURRING TO THE RV, ITS ELECTRICAL SYSTEM, OR ANY OF ITS COMPONENTS FROM THE USE
OF ANY ELECTRICAL ADAPTER.
110 VOLT AC SYSTEM
The
110 volt AC system in your unit is designed to provide safe power for operating AC powered
appliances and accessories in your unit. It is wired as a 50 amp, single phase system. Incoming power is
supplied to your unit from one of three sources:
Shore Power Cord
The “shore power” cord supplies electricity to the coach via the connection at the campground post.
