120-VOLT 30-AMP AC ELECTRIC SYSTEM (IF
EQUIPPED)
The 30-amp 120-volt 60hz AC electrical system is
designed to operate on 1 leg of 120-volt power at
a maximum current flow of 30-amps.
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 30-amp 120-volt 60hz AC
electrical system can be powered by the 120-volt
60hz utilities found in campgrounds or by 120-volt 60hz generator
power.
30-amp Power Cord
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.
Calculating 30-amp Electrical Load
When connecting appliances to the electrical system, 120-volt power
usage is limited to a total of 30 amps.

120-VOLT 50 AMP AC ELECTRIC SYSTEM (IF
EQUIPPED)
The 50 amp 120-volt 60hz AC electrical system
can be powered by an outside 120/240-volt
60hz utility service like those commonly found in
campgrounds or by 120/240-volt 60hz generator
power. The entire system is designed to operate
on 2 legs of 120-volt power at a maximum
current flow of 50 amps 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.
50-amp Power Cord
The 50-amp external utility power cord is commonly referred to as the
“shore” power cord. It is designed to mate and properly function with
50-amp “shore” power receptacles available at most campgrounds.
The shore power cord is designed to continuously carry the 50-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.
Calculating 50-amp Electrical Load
When connecting appliances to the electrical system, 120-volt power
usage is limited to 50 amps per electrical system leg for a total of 100
amps.

120-VOLT AC ELECTRIC SYSTEM
The following electrical components will only operate when connected to 120-volt power: air conditioner(s), refrigerator, microwave oven,
television(s), home theater system(s), water heater, washer, dryer, fireplace, electric stove, and appliances plugged into convenience receptacles.
These components will create a surge on the inverter.
A circuit breaker “trip” may occur if you overload the recreation vehicle and/or campground electrical system. Operating appliances collectively
places an added load on your 120-volt 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.
TESTING CAMPSITE POWER CONNECTION
The campsite 120-volt power receptacle(s) should
always be tested for proper functionality prior to
plugging in the recreation vehicle shore power
cord. Campsite 120-volt power receptacles can be
tested using a digital multimeter or a dedicated circuit
analyzer. Dedicated circuit analyzers plug directly into the campsite
power receptacle and minimally test for open neutral, open ground,
and correct polarity. If the ground monitor indicates ‘reverse polarity’
or an ‘open ground’ DO NOT connect the power cord.
Inspect RV power cords for cuts, cracks and worn insulation. Have
the power cord replaced immediately if these symptoms are noticed.
