CIRCUIT BREAKERS
The circuit breakers are resetable electrical circuit
protection devices. They stop the flow of current
in the event of a circuit overload. Once a circuit
breaker is tripped, reset manually by pressing 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.
The circuit breakers are located on each side of
the operator console.
The chart shows the circuit breakers and the
electrical components they protect.
