ELECTRICAL SYSTEM OPERATION UNITY MOTORHOME
If a circuit breaker “trips,” allow a brief cool down
period of 30–90 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 qualied
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�

The fuse rating for each dedicated circuit is
determined by the use and character of the
equipment on that circuit.
WARNING
POWER DISTRIBUTION PANEL
The power distribution panel
1
, located in a lower
cabinet fascia, contains the 120 volt breakers for the
120 volt AC system and 12 volt fuses for the 12V DC
system. Refer to your oor plan in the “Introduction”
section for the power distribution panel location�
1
The left side of the breaker panel
2
contains 120 volt
AC breakers. Refer to the circuit breaker panel decal
to identify the function of each breaker. The right side
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 ow of electricity in the
particular affected circuit of the system and helps
prevent damage or re.
