SECTION 3
ELECTRICAL SYSTEM – 50 amp
Y
our RV
contains separate low voltage (12-
volt DC) and high voltage (240/120-volt AC)
electrical systems. You must have a 120-volt
AC (VAC) power source if you are going to
use the microwave, roof air conditioner, the
refrigerator in the electric mode and the 120-
volt electrical outlets. For the most part
everything else in the RV works off of 12-volt
DC (VDC) power. If you look at the RV power
distribution panel you will see circuit breakers
like you have in your house for the 120 VAC
side, and automotive style blade fuses for the
12 VDC side.
Because the wiring and circuitry is engineered
by Jayco into a dedicated system specific to
your RV, we recommend you do not make
unauthorized changes or add fixed appliances
yourself. Only a qualified RV technician
should attempt to make changes or additions
to the electrical system. Approved materials,
components and methods of installation must
be used to meet safety and code
requirements.
Changes or additions made
to your RV may create a hazardous
condition and/or result in loss of warranty
coverage.

RECAUTIONS
Careless handling of electrical components
can be fatal. Always take the appropriate
safety precautions when working around the
RV electrical system.
Always make sure the electrical components
are turned OFF before disconnecting the
battery negative cable.
Always unplug the 50-amp power cord and
disconnect the negative battery cable before
working around the RV electrical system.
Never work around batteries with an open
flame. Vapors from the batteries can ignite,
causing serious damage.
Remove your rings, metal watchbands and
any other metal jewelry before working
around the RV electrical system
Use caution when using metal tools around
the RV electrical system. If a tool contacts a
battery terminal or metal connected to it, a
short circuit could occur which could cause
personal injury, explosion or fire.
Never touch or use electrical components with
bare feet, wet hands or while standing in
water or on wet ground.
NEVER
allow children to play with the
electrical system or components.

if possible:
a. Disconnect the shore line power cord
from the external power source.
b. Disconnect the auxiliary battery cables
(if applicable).
c. Turn OFF the generator (if applicable).
3. Check the fire to see if you can attempt to
put it out with the fire extinguisher. If there
is any doubt, call the local Fire
Department for emergency assistance.
4. Do not touch any electrical wires or
appliances.
Always have faulty or damaged wiring and
electrical components repaired before using
your RV again.

Your RV is equipped with a 240/120 VAC/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
Do not
attempt to use water to put out an
electrical fire. Water can spread some
types of fire, and electrocution is possible
with an electrical fire.
