SECTION 6-ELECTRICAL SYSTEMS JAYCO TOWABLE
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),
water heater, washer, dryer, fireplace, electric stove, and appliances plugged into
convenience receptacles.
50-AMP POWER CORD (IF SO EQUIPPED)
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 (IF SO EQUIPPED)
When connecting appliances to the electrical system, remember that 120-volt power usage
is limited to 50 amps per electrical system leg for a total of 100 amps. Be mindful of the
fact that each operating appliance collectively places an added load on your 120-volt
electrical system.
An unintentional “trip” of a circuit breaker may occur if you overload the motor home’s
and/or campground’s electrical system. The amperage rating of individual appliances can
be calculated by dividing appliance wattage consumed (normally listed on the appliance)
WARNING
Circuit breakers and fuses will not offer complete protection of the electrical
system in the event of power surge or voltage spike.
WARNING
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.
WARNING
PLUG INTO 50-AMP SERVICE ONLY.
