SECTION 6 – ELECTRICAL
Your motorhome is equipped with an
electrical system consisting of two separate
voltages:
•
12-volt DC system (battery current); and
•
120-volt AC system (household current)
The 12-volt system consists of two internal
power sources, while the 120-volt system is
operated from an outside power source or the
optional 120-volt generator.
ELECTRICAL CAUTIONS
•
Careless handling of electrical components
can be fatal. Never touch or use electrical
components or appliances while feet are bare,
while hands are wet, or while standing in
water or on wet ground.
•
Improper grounding of the vehicle can cause
personal injury. Do not plug the utility power
cord into an outlet which is not grounded and
do not adapt the plug to connect to a receptacle
for which it is not designed.
•
Do not attach an extension cord to the utility
power cord.
•
Be sure that all electrical appliances to be used
contain 3-prong plugs for proper grounding.
•
Avoid overloading electrical circuits. Replace
fuses or circuit breakers with those of the
same size and amperage rating only. Never
use a higher rated fuse or breaker.
•
Use caution when handling or working near
electrical storage batteries. Always remove
jewelry and wear protective clothing and eye
covering. Avoid creating sparks.
ELECTRICAL SYSTEM –
HOUSE 120-VOLT AC
The 120-volt system operates from the
shoreline cord connected to an outside 120-volt
utility service, such as those at campgrounds or
from the 120-volt generator. When the shoreline
cord is connected to an outside power source, or
when the auxiliary electric generator is running,
the power converter automatically changes a
portion of the 120-volt current to 12-volt DC
current. All equipment in the motorhome that is
normally powered by the house batteries is then
powered through the converter.
In addition, the following equipment is
entirely dependent on 120-volt current: air
conditioner, microwave oven, and any 120-volt
electrical equipment used at convenience outlets.
POWER CORD – EXTERNAL
(Shoreline)
The external power cord (commonly referred
to as a “shoreline”) is located in the utility
compartment or water service center, depending
on model.
The power cord is designed to ground the
electrical system through the receptacle. It is also
designed to carry the amperage output of most
campground outlets. If the electrical receptacle to
WARNING
Do not use an extension cord. Improper
sized cords, damaged cords, and poor
connections can lead to fire, which can
result in death or serious injury.
WARNING
Do not connect the external power cord to
any receptacle until you have verified
proper polarity and grounding. Be sure all
prongs of the supply cord are properly
plugged into the receptacle. Failure to
observe can result in death or serious
injury.
