SECTION 6
ELECTRICAL SYSTEM – 50 AMP
Your RV is equipped with a 240/120-volt
AC/50 amp power cord and load center. A
maximum of 50 amps (or 6000 watts) of
power can be consumed at any given time. It
may be necessary to stagger usage of some
appliances to maintain your power usage at
50 amps or lower. The 120-volt AC system
provides power to most of the appliances and
all of the electrical outlets.

REAKERS
The circuit breaker panel protects the 120-volt
electrical system from overloads, shorts in the
wiring and shorts in the connected
components. When an overload or short
occurs, the circuit breaker will open (or “trip”)
preventing any further flow of electricity and
damage to the RV.
If a circuit breaker has been tripped, shut OFF
the connected appliance (i.e., air conditioner,
microwave, etc.) and allow a brief cooling
period. Then reset the circuit breaker by
moving the appropriate switch OFF and back
ON. If the circuit breaker is continually tripped
and no overload is evident, contact your
dealer to have the electrical system tested
and repaired.
A circuit breaker identification label is
permanently attached to the inside surface of
the 120-volt load center. Circuit breakers will
not offer complete protection of the RV
electrical system in the event of a power
surge or voltage spike.
Maintenance and Replacement
At the beginning of camping season, inspect
the circuit breakers and replace as needed.
Test by turning each circuit breaker OFF and
back ON. Circuit breakers are wearable parts
and must be replaced as needed, as part of
your RV maintenance. If you have any
questions, consult your dealer.
Please contact your dealer for repair
assistance when replacing circuit breakers.

The 50 amp power cord is also commonly
referred to as the “shore line power cord.”
This power cord is designed to ground the RV
electrical system through the external power
source receptacle. It is also designed to carry
the voltage and amperage output of 50 amp
campground outlets.
Occasionally the electrical service provided by
a campground may experience low or high
voltage (i.e., surges or spikes). Any prolonged
exposure will shorten the life of the electrical
system and appliances. Consult your dealer
for recommendations on power surge
protection.
Plugging the shoreline power cord into an
incorrectly rated amperage service could
damage your motorhome electrical system
and result in severe or fatal injury.
Connecting the power cord
Always test the 50 amp external power source
(i.e., the campsite power box or electrical box)
with a ground monitor, before connecting your
power cord to it. If the ground monitor
indicates 'reverse polarity' or an 'open ground'
DO NOT
connect the power cord.
1. Turn OFF the load center main 240/120-
volt circuit breaker.
2. Carefully extend the entire length of the
power cord (approximately 25’-35’) from
the electric cable hatch to the external
power source.
3. Plug the power cord into the receptacle.
Be sure all the power cord prongs are
properly plugged into the receptacle.
4. Return to your RV and turn ON the load
center main circuit breaker.
Replacement circuit breakers must be of
the same voltage, amperage rating and
type. Never use a higher rated
replacement circuit breaker; doing so may
cause a fire by overheating the RV wiring.
5. To help prevent power surges from
damaging the connected loads, please
follow these instructions when hooking up
to the external power source:
