6.3 Circuit Protection
The AC circuit breaker protects the generator set from
extreme overload. The AC circuit breaker trips when it
detects a fault in the output circuit.
For application and selection information contact an
authorized distributor/dealer.
After correcting the fault, reset the AC circuit breaker by
placing it in the ON position. Restart the unit. See an
authorized service distributor/dealer for AC circuit
breaker ratings.
The unit's voltage configuration
determines the circuit breaker selection.
Note: Circuit breaker ampere rating and availability are
subject to change.

Circuit Breaker Considerations
Mounting location. Mount the circuit breaker in the
generator set's junction box.
Sizing.
Use the generator set voltage/frequency

to
determine
amperage. If the circuit breaker was sized for one
voltage configuration and later the generator set is
reconnected to a different voltage, change the circuit
breaker accordingly to provide optimum protection.
Have a qualified electrician or technician install circuit
breakers and reconnect the generator set. Comply with
all governing standards and codes.

generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative (--) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.

circuits to comply with applicable codes and standards. Never
contact electrical leads or appliances when standing in water
or on wet ground because these conditions increase the risk of
electrocution.
