INSTALLATION AND OPERATING INSTRUCTIONS
Warning: Gen/Tran transfer switches should be installed by a professional electrician familiar with electrical wiring and codes, and experienced in working
with generators. Gen/Tran accepts no responsibility for accidents, damages or personal injury caused by incorrect installation. These transfer switches are
intended for surface mounting outdoors or indoors.
Caution: If using the generator and transfer switch for larger appliances, such as electric water heaters, clothes dryers, electric ranges and small air
conditioners, check the labels on the appliances to be sure they do NOT exceed the rating of the generator. No appliance should have an amperage rating that
exceeds the “GENERATOR MAIN” rating in the transfer switch.
Thank you for purchasing the finest manual transfer switch available today. Gen/Tran’s Power Centers are designed to safely connect generators to load centers
in homes and light commercial buildings (single phase only) for standby power applications. Features include:
♦
♦
♦
♦
Generator Main and Utility Main mechanically interlocked preventing utility or generator power back feed
Full branch circuit protection with Siemens® circuit breakers
Optional GFCI, Arc Fault or Surge Protection circuit breakers to further protect your home and electronic equipment (Available from Gen/Tran)
High Corrosion-resistant aluminum cabinet
Items Needed for Installation:
♦

For “Hard-wired” Generator Connection: (Models R6010, R6020, R1020, R1220)
1. Follow steps 1 - 6 as described above.
2. Installer to determine size of conduit for bringing power from generator to the Power Center. KOs on bottom of Power Center should be
used, although alternate entry is adequate when necessary. Watertight hubs should be used above live breaker terminals. NOTE: If a 2” KO
is cut in the side of the Power Center enclosure, the dead front panel may need to be “notched” to clear the 2” fittings. The back of the KO
must be 3/8” from the rear of the enclosure.
3. Terminate wires from generator to “Generator Main” circuit breaker lugs on the Right side of the bus assembly. Terminate neutral and
ground wires into the appropriate bars provided.
4. Proceed with steps 7, 8 and 9 as described above.

NOTE: if Ground Fault Circuit Interrupting (GFCI) breakers, Arc-Fault breaker or surge protecting circuit breakers are used in the Power Center,
they will reduce the maximum number of circuits from the number shown in the table above. Also if circuit breakers larger than 50 amps are used
as sub-feed breakers, the maximum number of circuit breakers will also be reduced. Contact Gen/Tran at 1-888-GEN-TRAN for more information
on GFCI, Arc-Fault and Surge Protecting circuit breakers.
Operating Your Power Center Transfer Switch:
Transferring from Utility Power to Generator Power:
1. Move generator outdoors. WARNING: Operating a generator indoors or in a garage could result in injury or death.
2. Insert the male plug of the Power Cord into the correct outlet on the generator.
3. Plug in the female connector of the Power Cord to the inlet (if provided) located on the bottom of the Power Center.
4. Turn OFF all circuit breakers in the Power Center and Main load center.
5. Start the generator outdoors, following the procedures described in the generator’s owner’s manual furnished by the manufacturer.
6. Turn ON the GENERATOR MAIN circuit breaker in the Power Center.
7. Turn ON individual circuit breakers in the Power Center and the Main load center up to the continuous wattage rating of your generator. If the Generator
Main breaker trips, you have overloaded the generator. Some circuit breakers must be turned OFF to avoid damage to the generator or to the loads being
connected.

Transferring from Generator Power to Utility Power:
1. On the Power Center, turn OFF Generator MAIN breaker and turn ON Utility MAIN breaker. On 200 amps Main breaker models, this will require sliding the
interlock mechanism up with the left hand while turning ON the 200 amp circuit breaker.
2. Turn ON any branch circuit breakers in the Power Center and Main Load center that are OFF.
3. Shut down the generator, following the procedures in the generator Owner’s Manual.
4. Unplug the power cord from the Power Center and then the generator.
5. Let the generator cool down before storing in a dry, secured location.
6. To ensure that your generator will work properly when you need it, it is important to start and run your generator under load regularly and keep the tank
filled with fresh fuel. Perform the above steps at least ONCE A MONTH to keep the generator properly “exercised.”
