110-Volt Circuit Breakers
The breaker panel protects all 110-volt com-
ponents in the motor home from either an over-
load on the circuit or a short in the wiring or
component itself. When an overload or short
develops, the breaker will open preventing any
further flow of electricity and, therefore, damage
to the system.
Shut off the equipment (example: air condi-
tioner) and allow a brief cooling period. Then
reset the breaker by moving the switch to “Off”
and back to “On”. If the breaker continually trips
and no equipment is running, have the system
checked for a short in the wiring or the appli-
ances.
The 110-volt circuit breaker panel is located
behind the cabinet door under the refrigerator or
near the galley.
NOTE: See 12-Volt fuse panel in 12-volt DC
system elsewhere in this section.
Further Information
Refer to the converter manufacturer’s infor-
mation provided in your Owner InfoCase for
additional information about your power con-
verter system.
Charging Section
The house batteries are automatically charged
while 110-volt external power is connected. The
charger will automatically “sense” the condition
of the RV battery. If it is below “full charge”, the
Charging Section will start charging the battery.
If the house batteries have been extremely dis-
charged, they will accept charge at a relatively
high amperage rate. If they are only slightly dis-
charged, they will charge at a lower amperage
rate. The rate of charge will decrease as the bat-
teries reach “full charge”, then will remain “trick-
le” charging at a very low amperage rate. If your
storage battery does not charge as described
above, it is possible the battery is defective.
NOTE: We do not recommend leaving the shore-
line plugged in continuously during stor-
age periods because the batteries can
lose electrolytic fluids and become dam-
aged from continuous charging without
periodic use. We recommend following
regular battery inspection and mainte-
nance, especially in cold weather. See
“Battery Storage & Maintenance” at the
end of this section.
Thermal Overload Protector
A thermal overload protector will shut down
the converter if it becomes overheated. This can
result from operating above its maximum limit
for an extended period of time or by obstruction
of ventilation to unit.
NOTE: 12-volt lights and motors will automati-
cally draw from battery power in this
event.
The thermal breaker will reset itself after a
cool-down period, and the lights and motors will
resume operating from the converter. If the over-
load trips again shortly after reset, take immedi-
ate steps to correct the cause of overheating. A
portion of house 12-volt load (lights or motors or
both) should be turned off to reduce total load.
Also, inspect the converter unit to make sure ven-
tilation is not obstructed.
110-Volt House Circuit Breakers
Do not store items too closely around
the inverter unit in the storage com-
partment. The inverter generates heat
while operating and needs unre-
stricted airflow for proper cooling.
