HOUSE ELECTRICAL - INTRODUCTION
The motorhome 120/240 Volt AC system can be operated from three different power sources: shore
power, the on-board generator or the inverter/charger. Shore power is the most efficient and should be
used whenever possible. The generator can be used when shore power is unavailable. The
inverter/charger supplies silent AC power using the house batteries of the motorhome. The AC power
output is limited and should be used sparingly.
Two different sources supply the main AC circuit breaker panel with power: the 50 Amp shore
power cord or the on-board generator. The power source used is automatically selected by a switching
device known as a transfer switch. The inverter supplies AC power to the sub-panel.
WARNING:
The electrical system is engineered and tested for complete safety. Circuit breakers
and fuses protect the electrical circuits from overloading. When planning modifica-
tions or additions to the electrical system, we strongly recommend consulting the deal-
er for assistance to ensure continued integrity and safety of the electrical system.
Please note that any modifications may void the warranty.
WARNING:
Water is electrically conductive. Do not use any electrically powered item or electrical
outlet that may be exposed to a water source. Such use can result in a serious shock
causing injury or death.
Shore Power:
The motorhome is equipped with a shore power cord to connect the motorhome to outside electri-
cal services. Shore power service is the most efficient source of electrical power. The plug end of the
shore power cord is 50 Amp, 240 Volt. When this type of power service is not available, electrical
adapters will be required to allow a proper and safe connection to the electrical service supply.
NOTE:
When 50 Amp shore service is not available, care will have to be used when operating
the appliances and using the outlets to avoid overloading the shore power service.
Generator:
The generator can be selected for use when shore power is unavailable. The maximum amount of
generator output power, measured in watts, is calculated at an elevation of 500 feet above sea level. This
figure will decrease slightly at higher altitude. Ambient temperature also effects total maximum output.
The amount of AC electrical load applied to the generator determines fuel consumption.
