Section 6: Electrical System
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 reconfigure
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 recreation vehicle can cause personal injury or death.

The 30-amp external utility power cord is commonly referred to as the “shore” power cord. It
is designed to mate and properly function with 30-amp “shore” power receptacles available
at most campgrounds.
The shore power cord is designed to continuously carry the 30-amp current flow required to
power each leg of the electrical system. It also creates a critical ground connection between
the vehicle electrical system and the campground shore power receptacle.
Always test the external power source (i.e., the campsite power receptacle or electrical
box) with a ground monitor before connecting your power cord to it. If the ground monitor
indicates ‘reverse polarity’ or an ‘open ground’
DO NOT
connect the power cord.
Regularly inspect the shore power cord for cuts, cracks, worn insulation and other damage.
Have the power cord replaced immediately if problems exist.
Calculating 30 AMP Electrical Load (If So Equipped)
When connecting appliances to the electrical system, 120-volt power usage is limited to a
total of 30 amps. Operating appliances collectively places an added load on your 120-volt
electrical system.
An unintentional “trip” of a circuit breaker may occur if you overload the recreation vehicle
and/or campground electrical system. The amperage rating of individual appliances can be
calculated by dividing appliance wattage consumed (normally listed on the appliance) by
nominal design voltage (120 for a 120-volt appliance). For example: 1200 watts divided by
120-volts equals 10 amps.
Generator
Your motor home may be equipped with an LP or diesel powered generator. The generator
in your motor home produces 120/240-volt power compatible with the motor home electrical
system. It can be used to power the entire motor home when 120/240-volt shore power is
not available.
