50 AMP S
YSTEM
Make very certain the external power source (50 amp systems only) you
connect the power cord to is a 50 amp NEMA 14-50 RV receptacle and not
240 volt AC.
Your RV may be equipped with a 50 amp 120-volt 60hz AC electrical system. The
entire system is designed to operate on 2 legs of 120-volt power at a maximum
current flow of 50 amperes per leg. Exposure to voltages higher or lower than a
nominal 120-volts will damage or shorten the service life of the electrical system
and appliances. The 50 amp 120-volt 60hz AC electrical system can be powered
by the 120-volt 60hz utilities found in RV campgrounds or by 120-volt 60hz
generator power.

The power cord is also commonly referred to as the "shore power cord." This
power cord is designed to ground the RV electrical system through the external
power source receptacle. It is also designed to carry the voltage and current
output from campground power receptacles.
Occasionally the electrical service provided by a campground may experience low
or high voltage (i.e., surges or spikes). Any prolonged exposure will shorten the
life of the electrical system and appliances. Consult your dealer for
recommendations on power surge protection.

Do not hook up the power cord to any receptacle until you have verified
proper polarity and grounding. Polarity indicators can be purchased in
most electrical and hardware stores.

Do not use any cheater plug, adapter or extension cord to reduce
incoming AC power or break the continuity of the circuit connected to the
grounding pin.

Do not connect the power cord into an outlet that is not grounded, or
adapt the power cord plug to connect it to a receptacle for which it is not
designed.

Do not remove the grounding pin to connect to a non-grounded
receptacle. Removal of the ground pin disables an important safety
feature designed to prevent shock and electrocution hazards.

Do not connect the power cord to an extension cord. Use of an improper
extension cord will cause overheating of the cord as well as potentially
causing premature failure of the AC equipment.
It is the responsibility of the owner of the electrical receptacle to ensure that
the receptacle is properly wired and grounded. Reverse polarity and/or
improper grounding of your RV can cause personal injury or death.
