Operation
Changing Back to 208V Configuration
When finished with the 240V settings, change the alarm
settings back for the 208V configuration. Follow steps 1-
19 above, changing the Pre-alarm Trip to 132V and the
Alarm Trip to 134V.
NOTE:
Verify the Pre-alarm Trip setting is adjusted
before the Alarm Trip setting in order to set the Alarm Trip
setting.
Customer Convenience Receptacles
The unit is equipped with five receptacles. The 240/
120VAC twist-lock receptacles are rated at 50A each.
The 120VAC duplex receptacles are rated at 20A each,
with ground fault circuit interrupt (GFCI) protection. The
receptacles are not routed through the main circuit
breaker. Each receptacle has its own circuit breaker,
located directly above or next to the receptacle. Each
breaker is sized to the maximum rating of the
corresponding receptacle.
Figure 3-6. Receptacle and Breaker Locations
NOTE:
Power to the receptacles is available any time
the generator is running, even if the main circuit breaker
is OFF (O). Verify equipment connected to the
receptacles is turned OFF before turning the breakers
ON.
NOTE:
When the voltage selector switch is in position for
480/277V 3Ø, voltage at the two GFCI receptacles is 139
volts and the voltage at the three twist-lock receptacles is
240/139 volts. Generac Mobile Products LLC does not
recommend using the receptacles in the 480V position.
When the voltage selector switch is in position for 208/
120V 3Ø, voltage at the three twist-lock receptacles and
the two GFCI receptacles is 208/120 volts.
Main Circuit Breaker
See
. The main circuit breaker is located on
the main control panel. When the breaker is OFF (O),
power is interrupted to the connection lugs, the optional
cam lock receptacles, and the generator. Once the
connections have been made to the connection lugs or
the optional cam lock receptacles, and the unit has been
started and allowed to reach normal operating
temperature, the breaker may be switched ON (I).

Verify any problems that cause the main circuit breaker to
trip are corrected before returning the switch to ON (I).
NOTE:
The main circuit breaker interrupts power to the
connection lugs and the optional cam lock receptacles
only. The customer convenience receptacles have power
even if the main circuit breaker is OFF (O). To disconnect
power to these receptacles, use the individual circuit
breakers located near each receptacle.
