ELECTRICAL SYSTEM
General
The electrical system in the recreation vehicle is composed of 120-volt AC (alternating current)
and 12-volt DC (direct current) capabilities. All installations are made in compliance with safety
requirements of ANSI standard A.1192 National Electric Code, Canadian Standards Association,
NFFA-70.
Wiring code for 120-volt AC system is:

Power Center
Your motorhome is equipped with a power center that includes 120-volt breakers, 12-volt fuses,
and battery charging capability. Access to the breakers and fuses is located behind the removable
panels on the power center. Your motorhome is also equipped with a transfer switch that
automatically switches between generator power and external power.
120-Volt AC System
Your motorhome is equipped with a 30-Amp power cord pre-wired into the power center to
provide 120-volt power to the unit. By opening the cable hatch you can pull the power cord out
from the compartment and attach it to a commercial power source. The power cord extends
approximately twenty to twenty-three feet from motorhome. Power flows through the 30-amp
main circuit breaker and is then distributed through branch circuit breakers to wall receptacles and
appliances.
To prevent accidental electrical shock, insure that the ground pin on the attachment plug cap is
grounded through the RV park receptacle. When plugged into a receptacle with no provision for
the third pin, use an adapter with a pigtail that can be connected to the receptacle box so the
grounding circuit is completed through the ground pin or RV park receptacle box. Any accidental
short of a live circuit conductor will trip the circuit breaker indicating a shorted circuit. Be certain
that the polarity of the external power is not reversed in order to avoid harm to appliances and
personal electrical shock. Polarity indicators may be purchased in most electrical and hardware
stores.
It is strongly recommended to avoid the use of extension cords. If an extension cord is used, it
MUST be the same amperage rating as the RV power cord. Using an improper extension cord will
cause overheating of the cord and equipment as well as possibly causing premature failure of the
AC equipment.
y
WARNING: Do not use an adapter, cheater plug or extension cord that will break the
continuity of the grounding circuit. Never remove the grounding pin to connect a
non-grounded, two-prong receptacle. Any deviation from this will potentially cause a
fire from overheating.
