CIRCUIT BREAKERS
The circuit breakers are resetable electrical circuit
protection devices. Their design stops the flow of
current in the event of a circuit overload. Once a
circuit breaker is tripped, it must be reset
manually. Press the reset button after the breaker
has cooled down.
If the overload that caused the circuit breaker to
trip is still there, the circuit breaker will continue to
stop current flow until the problem is corrected.
All the circuit breakers are located in the operator
compartment except CB--10. It is located in the
cab control panel.
The chart lists the circuit breakers and the
electrical components they protect.
