Section 6: Electrical System
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 indi-
cates '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.
120-Volt (50 AMP) AC System (if so 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 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 an outside 120/240-volt 60hz utility service like those commonly
found in campgrounds or by 120/240-volt 60hz generator power.
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), wa-
ter heater, washer, dryer, fireplace, electric stove, and appliances plugged into convenience
receptacles.
Circuit breakers and fuses will not offer complete protection of the elec-
trical system in the event of power surge or voltage spike.
Make certain the external power source you connect the power cord to is
a properly wired 50 amp NEMA 14-50 RV receptacle and not 240 volt
AC. PLUG INTO 50-AMP SERVICE ONLY.
