CONSUMPTION OF 120-VOLT AC POWER
Your recreation vehicle is equipped with a 120-volt/30 ampere power cord and load center.
A maximum of 30 amperes (or 3600 watts) of power can be consumed at any given time. It
may be necessary to stagger the use of some appliances to maintain power usage at 50
amperes or below. Accessories such as coffee pots, toasters, electric skillets, curling irons,
etc. can use a significant amount of power and need to be included in your power
consumption plan.
12-Volt DC (Direct Current) System
.
NOTE: The motorhome master battery switch MUST be turned on before 12-volt
devices will operate.
Included with your power center is a power converter which transforms 120-volt AC
energy into 12-volt DC energy to supply your motorhome. When 120-volt AC power is
supplied to the power center through the main circuit breaker in the "ON" position, the
converter will supply 12-volt DC power to the motorhome as long as the auxiliary battery is
properly connected.
Electrical component parts are sensitive to heat and the power converter will produce heat.
Ventilation is required for proper operation. A fan is built into the power converter to assist
air movement and provide temperature control. If normal ventilation is obstructed and the
fan is unable to control the temperature, a protective "Thermal Breaker" will trip the
120-volt AC power to the power converter. After the converter cools down, the breaker
will reset automatically and 12-volt DC power will be restored.
Replaceable fuses are used to protect the 12-volt DC component parts. If a fuses blows, it is
an indication that a circuit is overloaded or there is a "short circuit." Contact your
independent, authorized dealer for assistance.
A separate 12-volt fuse panel supplies power to your chassis. Consult the chassis owner's
manual for assistance.
When 120-volt AC power is supplied to the power converter through a direct connection at
the campsite, the converter will supply 12-volt DC power to the auxiliary battery
automatically.
The auxiliary battery will also receive a charge from the alternator when the engine is
running.
Batteries, Chassis and Auxiliary
Each chassis is built with a battery to provide energy to start the engine and supply energy
for other component parts in the chassis. This battery is located under the hood. The
original equipment manufacturer (OEM) chassis battery is furnished and warranted by
your Ford or GM dealership (as applicable).
An auxiliary battery is included in each motorhome for storage power when 120-volt
energy is not available. When drawing energy from the battery, remember that there is a
limited amount of power available before the battery needs to be recharged. This auxiliary
battery is located in the "house portion" of your motorhome. All auxiliary batteries require
an "in-line" fuse, or a 12-volt circuit breaker, placed within 18" of battery for your
protection.
