POWER DISTRIBUTION PANELS
The power distribution panels
1
, located in a lower
cabinet fascia, contain the 120 volt breakers for the 120
volt AC system and 12 volt fuses for the 12V DC system.
Refer to your floor plan in the “Introduction” section for
the power distribution panel locations.

The lower breaker panel
2
contains 120 volt AC
breakers. Refer to the circuit breaker panel decal to
identify the function of each breaker. The upper panel
3
contains 12 volt DC fuses. Refer to the circuit fuse
panel decal to identify the function of each fuse.

120 VOLT AC CIRCUIT BREAKERS
The circuit breaker panel protects all 120 volt AC
equipment and components in the motorhome
from overload, a short in the wiring or a short in the
component itself. In the event of an overload, the circuit
breaker cuts off the flow of electricity in the particular
affected circuit of the system and helps prevent damage
or fire.
If a circuit breaker “trips,” allow a brief cool down period
of 3090 seconds, then reset the breaker by turning
it “OFF” and then “ON.” If a circuit breaker “trips”
repeatedly, the circuit is overloaded or there may be a
short in the wiring or in the equipment, and both should
be checked and serviced by qualified service personnel.
Refer to the control panel manual in the Motorhome
Information Kit for further details.
NOTE: There is a single 30 amp main circuit breaker
which protects the entire AC electrical system. Check
the main breaker if the entire electrical system will not
function on shore power or generator (if equipped).
12 VOLT DC COACH FUSES
Each 12 volt DC system circuit is protected by a
dedicated fuse. When a fuse blows (refer to Figure
4
),
shut off all appliances or lights on the affected circuit and
replace the fuse with a new one of the same amperage.

ᘐ WARNING
The fuse rating for each dedicated circuit is
determined by the use and character of the
equipment on that circuit.
