Connecting Loads
Loads can be connected to the generator by the Output
Terminal Lugs or the convenience receptacles (Figure 18).
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 19) 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 19. 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).
