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, 110 amp main circuit breaker is provided. Make sure to switch ALL circuit breakers to the OFF position prior to starting the engine.

Figure 11. Connecting Loads

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.
