Section 6: Electrical System
Load Center
The Load Center contains 12VDC fuses and 120VAC circuit breakers for almost all of the
electrical appliances and circuits in the RV. The 120V main breaker may be located in this
panel and will turn off all 120-volt power to the RV. Load center location, appearance and
configuration may vary by model. Refer to the diagram inside the load center for specific
fuse assignments.
Motor homes may have separate small panels for breakers and fuses. They are normally
located in close proximity to each other typically in the bed platform. The converter is
mounted separately, typically under the bed platform.
120-Volt Circuit Breakers
The 120-volt AC circuit breakers located inside the load center protect all 120-volt wiring
and components 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 it cools down,
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.
Circuit breakers and fuses will not offer complete protection of the electrical
system in the event of power surge or voltage spike.
