120-VOLT CIRCUIT BREAKERS
The 120-volt AC circuit breakers located inside the main load center protect all
120-volt wiring and components in the RV from circuit overloads and short circuits.
Should a circuit overload or short circuit occur the circuit breaker protecting the
affected circuit will “trip” preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut “off” the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever “off” and
then back to the “on” position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker “off” and back “on”. Circuit breakers
are wearable parts and must be replaced as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned “off”. Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel. There are no
customer serviceable parts inside the converter case and the
manufacturer’s warranty will be void if the case has been removed. If you
have further concerns contact your dealer.
CAUTION
Circuit breakers and fuses will not offer complete protection of the electrical
