TRANSFER TO GENERATOR POWER SOURCE
WHEN UTILITY POWER FAILS
1. Move generator to within approximately 10 feet of the
power inlet box. Connect ground strap to the
generator’s grounding lug and to the grounding rod.
2. Open the door of the Manual Transfer Switch. Slide the
mechanical interlock connecting the 60 Amp and 50
Amp circuit breakers at the top of the panel to turn “Off”
the “Utility” circuit breaker. Both circuits will be in the
“Off” position.
3. Flip the “Standby” circuit breaker handle to the “On”
position. Close the door of the Manual Transfer Switch.
4. Open the power inlet box. Insert and lock the 50 Amp
female receptacle into the male receptacle in the
external connection box. Insert the 50 Amp plug into the
50 Amp NEMA 14-50 receptacle located on the
underside of the generator’s control panel. A retaining
clip is supplied on the control panel. Secure the
retaining clip over the end of the plug. The retaining clip
ensures that the plug remains in place during generator
operation.
5. Before starting the generator, verify the 50 Amp circuit
breaker on the generator’s control panel is in the “Off”
or “Open” position.
6. Start the generator and allow it to warm up for a couple
of minutes. Switch the 50 Amp circuit breaker on the
generator control panel to the “ON” or “Closed”
position.
7. The generator is now supplying power to the load center
circuits in the manual transfer switch.
TRANSFER BACK TO UTILITY POWER
SOURCE
When utility power has been restored, you will want to
transfer back to that power source and shut down the
generator. This can be accomplished as follows:
1. Switch the 50 Amp circuit breaker on the generator
control panel to the “OFF” or “Open” position.
2. Release the retainer clip from the NEMA 14-50 plug and
remove the plug from the outlet on the generator. Twist
and remove the 50 Amp female receptacle from the
power inlet box. Close and lock the box. Coil the power
cord and place it with the generator.
3. After the generator has run for a couple minutes to cool
down, turn off the generator.
4. Open the door of the Manual Transfer Switch and slide
the mechanical interlock to turn “OFF” the “STANDBY”
circuit breaker. Both circuit breakers will be in the “OFF”
position.
5. Flip the “UTILITY” circuit breaker handle to the “ON”
position. Close the door of the Manual Transfer Switch.
6. The Utility is now supplying power.
7. Disconnect the ground strap from the grounding rod
and the generator’s grounding lug. Retain the ground
strap with the generator. Return the generator to its
storage location.

Section 6—Operation of Generator with Manual Transfer Switch
Choose a lamp or light fixture located in a frequently
occupied area of the building as a signal light to tell
you when utility power has been restored. This light
should be on a utility powered circuit only, so it
operates independent of the generator.
