House Electrical - Introduction; Shore Power; Generator - Holiday Navigator 2003 Owner's Manual

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 on board generator can be used when shore power is unavailable. The
inverter/charger supplies silent AC power using the house batteries of the
motorhome. This source has limited AC power output 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 selected automatically by an automatic electrical switching
device known as a transfer switch. The inverters supply 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. If you plan modifications or
additions to the electrical system, we strongly recommend
consulting your dealer for assistance to ensure continued
integrity and safety of the electrical system. Please note that
any modifications may void the warranty.
The motorhome is equipped with a shore power cord. The electrical cord
connects the motorhome to outside electrical services. Shore power service is
the most efficient source of electrical power. Use this as the primary power
source. The plug end of the shore power cord is 50 Amp 220 Volt. Many
facilities are equipped with this power service. 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: In instances when 50 Amp shore service is not available,
care will have to be used when operating the appliances and
using the outlets so the shore power service will not be over-
loaded.
The generator can be selected for use when AC shore power is not available.
The generators maximum amount of output power, measured in watts, is
calculated at an elevation of 500 feet above sea level. This figure will decrease
slightly with a higher altitude. Ambient temperature also effects total
maximum output. The amount of AC electrical load applied to the generator
determines fuel consumption.
