EARTHBOUND RECREATIONAL VEHICLE TRAILER OWNER'S MANUAL
110-VOLT ELECTRICAL SYSTEM
City Power
The Earthbound RV converter system enables you to use the lights and appliances whether operating on selfcontained
battery power or hooked up to 110-‐volt city power. The 12-‐volt light bulbs give off the same
light as regular household bulbs, so that when operating on self-‐contained battery power, everything works
normally except the 110-‐volt convenience outlets and 110-‐volt appliances.
Exterior outlets for 110 volts are located on the curbside exterior wall between the wheels and above the
wheel well.
CAUTION
: When operating with city power make very certain that the service is 110 volt and not
220 volt.
The converter system is a transformer designed to maintain constant output voltages regardless of the
variances that occur in city power systems. The design eliminates the need for complex electronic sensing
systems to charge the batteries, minimizing the possibility of failures and greatly increasing its overall
reliability.
WARNING
: When the three-pronged plug can be used there will be no problems with
proper polarity or grounding.
To operate self-‐contained, simply disconnect the power supply cable.
When your trailer is hooked up to 110 volt AC, the converter system automatically charges the trailer
battery. The speed and degree of charge depends on how much power is used for lights and appliances, as only the
surplus goes to charging the battery. If you are making an extended stay, then you should keep your trailer hooked up
to a 110 volt current if it is available.
While you are connected to the 110-‐volt receptacle the wiring is protected by circuit breakers in the breaker
panel. The circuit breaker panel for the 110-‐volt system is located in the converter.
In the event of a failure of a 110-volt circuit, first check
your trailer circuit breakers and the breaker for the
outlet your trailer shoreline cord is plugged into.
If a breaker continues to trip after you have reset it several times, your circuit may be overloaded with
appliances or there may be a short in the circuit. Try lessening the load on the circuit. If that does not solve the
problem consult your Earthbound RV dealer for assistance.
The 110-‐volt electrical system provides power to operate the air conditioner, converter and 110-‐volt
receptacles for portable appliances. The power is carded through the 110-‐volt city power flexible cord to
the 110-‐volt distribution panel, and then is distributed to each appliance or receptacle.
All wire, components, and wiring methods conform to federal and state requirements.
GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
When properly installed, the GFCI circuit breaker provides reliable overload and short circuit protection
PLUS protection from Ground Faults that might result from contact with a "HOT"' load wire and ground.
IMPORTANT NOTE:
The GFCI circuit breaker will NOT reduce shock hazard if contact is made
between a "HOT" load wire and a neutral wire or 2 "HOT" load wires.
While the GFCI circuit breaker affords a high degree of protection, there is no substitute for the knowledge
that electricity can be dangerous when carelessly handled or used without reasonable caution.
WARNING
: The GFCI circuit breaker provides protection only to the circuit to which it
is connected. It does NOT provide protection to any other circuit.
