connecting loads
Loads can be connected to the generator by the
Output
terminal lugs or the convenience receptacles (Figure 11).
Make sure to read the operation manual before attempting
to connect a load to the generator.
To protect the output terminals from overload, a 3-pole,
800A
main circuit breaker is provided. Make sure to switch
all circuit breakers to the OFF position prior to starting
the engine.

Over current Relay
An
over current relay (Figure 12) is connected to the main
circuit breaker. In the event of an overload, both the circuit
breaker and the over current relay may trip. If the circuit
breaker can not be reset, the
reset button on the over
current relay must be pressed. The over current relay is
located in the control box.
Figure 12. Over Current Relay
NOTICE
Remember the
overcurrent relay monitors the current
flowing from the
u,v, and W output terminal lugs
to the load.
In the event of a short circuit or over current condition,
it will automatically trip the 800 amp main breaker.
To restore power to the
Output Terminal panel, press
the reset button on the overcurrent relay and place the
main circuit breaker in the closed position (ON).
