ELECTRICAL SYSTEM
General
The electrical system in your motorhome consists of 120-volt AC
(alternating current) and 12-volt DC (direct current) circuits and
components. All installations are made in compliance with safety
requirements of ANSI standard A.1192, National Electric Code, and
Canadian Standards Association.
Wiring code for 120-volt AC system:
Black = Hot or Positive
White = Neutral or Negative
Green/Bare = Ground
Caution: Power surges experienced while plugged in at a campground could
potentially damage electronic component parts in your recreation vehicle. Damage
from power surges are not covered by your Jayco warranty. Consult the component
part manufacturer's owner's manual or your independent, authorized dealer for
recommendations on power surge protection.
120-Volt AC System
POWER CORD
Your motorhome is equipped with a 30-amp rated power cord pre-wired into the breaker
box. By opening the cable hatch or utility center door you can pull the power cord out from
the compartment and attach it to the campground power source. Power will enter the coach
through a main circuit breaker. It is distributed through additional circuit breakers to wall
receptacles and any appliances wired direct, such as an air conditioner. The cord extends
approximately 25'–35' (7 to 10 meters) from the motorhome depending on floor plan.
Your RV power cord must be fully extended and not left coiled in the compartment or on
the ground. If the cord is left coiled, it creates potential for heat to melt the cord's casing
together.
To prevent accidental electrical shock, insure that the ground pin on the attachment plug
cap is intact to the earth ground through the RV park receptacle. Any accidental short of a
live circuit conductor will trip the circuit breaker indicating a shorted circuit. Make sure
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. Using an improper
extension cord will cause overheating of the cord and equipment, and it voids the warranty.
It may also cause premature failure of the AC equipment. If you choose to use an extension
cord, it MUST be the same amperage rating as the RV power cord and be identified for
heavy-duty outdoor use. However, the use of an extension cord can still cause all the
problems discussed here and will void the warranty.
I
WARNING: Do not use an adapter, cheater or extension cord that will
break the continuity of the grounding circuit connected to the third pin.
