Holiday Neptune 2004, Owner'S Manual

Page: 279 / 416

The standard electrical system of the motorhome consist of 120 Volt AC and
12 Volts DC (direct current) systems. The motorhome 120/240 Volt AC system
can be operated from three different power sources: shore power, the on-board
generator or an optional inverter. 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 optional inverter supplies silent AC power using the house
batteries of the motorhome. This source has limited AC power output and should
be used sparingly.
The motorhome 120 Volt AC is equipped with a UL listed power cord, a UL
listed circuit breaker panel, transfer switch, converter and generator. Additionally a
1500-watt inverter package and energy management package can be installed.
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 optional 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. 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.
WARNING: Water is electrically conductive. Do not use an
electrically powered item or an electrical outlet that may be
exposed to water. Use of such may result in injury or death from
a serious electric shock.
The AC system power requirement for the motorhome is 120/240 Volt AC
single phase. This can be 20 Amp, 30 Amp or 50 Amp service. Ensure the power
distribution panel is configured to handle the load. If shore power service is
available, connect the motorhome to the shore power source using the supplied
shore power cord. Shore power service is the most efficient source of electrical
power. The plug end of the shore power cord is 50 Amp 240 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. The electrical adapter will enable the shore power
cord plugs to be "dog boned" to the smaller receptacles. The motorhome shore
power cord is located on the roadside of the motorhome.
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 overloaded.
