This illustration
shows 50 amp,
30 amp, and
15-20 amp
outlets, along with
corresponding
circuit breakers.
WARNING
THIS CONNECTION IS FOR 110-125-VOLT
AC, 60 HZ, 30 AMPERE SUPPLY.
DO NOT EXCEED CIRCUIT RATING.
EXCEEDING THE CIRCUIT RATING MAY
CAUSE A FIRE AND RESULT IN DEATH
OR SERIOUS INJURY.
A Warning Label,
similar to the one
shown here, is
affixed on your
m o t o r h o m e ,
near the 30 amp
shore line cord
inlet.
30 Amp, 120 Volt Shore Line Power Cord
Your Class B motorhome is designed for 30 amp electrical ser-
vice, a 30 amp shore line power cord is provided to attach the
motorhome to a grounded 110-125 volt AC, 30 amp external
power source.
NEVER CONNECT YOUR SHORE POWER CORD TO AN
ELECTRICAL SOURCE THAT SUPPLIES MORE THAN
120 VOLTS AC.
Always turn OFF the main power switch or circuit breaker of
the shore power electrical outlet before connecting or discon-
necting the shore line power cord. This will eliminate arcing of
electrical contacts and reduce the potential of electrical shock.
Please strictly follow all electrical-related safety labels affixed to
your motorhome.
NOTE: Connect the pronged (or male) end to the
shore power cord to the external electrical service,
and the socket (or female) end to the motorhome’s
electrical connection port.
Connecting to an External Power Source
Inquire with the campsite owner or manager if they provide
the electrical service your motorhome requires. It is always
advisable to ensure the external electrical source is properly
wired and grounded before connecting your motorhome.
If the external electrical source is confirmed to be appropriate
for your motorhome’s electrical system, follow this electrical
hook-up procedure:
MOTORHOMES THAT ARE FACTORY-EQUIPPED WITH
A 30 AMP ELECTRICAL SERVICE SHOULD NEVER
BE CONNECTED TO A POWER SOURCE THAT WILL
PROVIDE MORE THAN 120 VOLTS AC.
Although the 3-prong, 30 amp RV connectors look similar
to 240 volt AC connectors found in residential homes
(electrical dryers, stoves, etc.), the 30 amp RV power
service is designed for 120 volts AC only.
Failure to follow this power requirement will result in
serious damage to appliances and electrical devices.
WARNING WARNING
Typical shore line power cord
connection port
1. Locate the load center
inside your motorhome
and turn OFF the main
AC circuit breakers.
Some panels will
have two main circuit
breakers.
2. Carefully extend the
entire length of the shore
line power cord (approx-
imately 35 feet) from the
electric cable port on the
motorhome to the exter-
nal power source.
3. Ensure the circuit
breaker(s) at the external
power source are OFF.
4. Connect the shore power
cord to the receptacle on
the motorhome. If the
connector has a locking
ring, carefully engage
the threads until snug.
Some connector designs
may require a slight twist
after insertion.
5. Plug the shore line power cord into either the 30 amp or
50 amp external power receptacle, matching the power
requirements and power cord connector of your motor-
home. Be sure all the connector prongs are properly and
completely inserted into the power source receptacle.
6. Turn ON the circuit breaker at the external power source.
7. Turn ON the main circuit breaker(s) at the motorhome’s
load center.
