2.7 Circuit Protection
If the generator set circuit breaker trips or the fuses blow
repeatedly, see Section 4 for possible causes.
2.7.1 Line Circuit Breaker
A line circuit breaker interrupts the generator output in

and the load. The line circuit breaker location is shown
in Section 1. If the circuit breaker trips, reduce the load
and switch the breaker back to the ON position.
2.7.2 Fuses
The junction box contains five fuses. See Figure 1-1 for
the fuse locations. Always identify and correct the cause
of a blown fuse before restarting the generator set.
