120-Volt AC GFCI Receptacles
NOTICE
It is recommended that the GFCI receptacles be tested
when the generator is initially uncrated. The receptacles
should then be tested daily at startup.
There are two 120-volt, 20-amp GFCI (duplex NEMA 5-20R)
receptacles provided on the output terminal panel. These
receptacles can be accessed in any voltage change-over
board position. Each receptacle is protected by a 20-amp
circuit breaker. These breakers are located directly above
the GFCI receptacles. Remember that the load output
(current) of both GFCI receptacles is dependent on the
load requirements of the U, V, and W output terminal lugs.
Press the Reset button (Figure 13) to reset the GFCI
receptacle after it has been tripped. Press the Test button
in the center of the receptacle to check the GFCI function.
Both receptacles should be tested at least once a month.
Reference the maintenance section in this manual for
further testing of the GFCI receptacle.

CONNECTING LOADS
Loads can be connected to the generator (Figure 14) via
the UVWO terminal lugs or the convenience receptacles.
Be sure to read the operation manual before attempting to
connect a load to the generator.
To protect the UVWO output terminals from overload, a
3-pole, 1600-amp, main circuit breaker is provided. Be
sure to switch all circuit breakers to the OFF position prior
to starting the engine.

OVERCURRENT RELAY
An overcurrent relay (Figure 15) is connected to the
main circuit breaker. In the event of an overload, both the
circuit breaker and the overcurrent relay may trip. If the
circuit breaker cannot be reset, the Reset button on the
overcurrent relay must be pressed. The overcurrent relay
is located inside the control box.
