Q: Hi Jim. I am buying the Generac 17500 to handle 8 circuits in house on 15 to 20 amp 120 breakers.

I also want to run a 3 ton central air unit on 30-amp 220 breaker.

The total wattage won't exceed 15,000 even with air.

Does this setup meet my needs or do I need a separate transfer switch for the air?

by Gary Pica from Ohio on July 06, 2012

A: Gary, you're close. The transfer switch is a good choice. You also need the appropriate power cord and power inlet box to connect everything together.

We recommend this power transfer system for the Generac 17500 watt portable generator:

Q: What does model 501210 (Gen-Tran 50A) come with to hook it up?
by Bill Cote from Massachusetts on March 13, 2012

A: Features include:

• Generator Main and Utility Main are mechanically interlocked preventing utility or generator power back feed.
• Full branch circuit protection with Siemens® circuit breakers.
• Dual watt meters help monitor and balance generator load, prolonging generator life.
• Pre-Assembled wire harness for easy connection to the load center.

Other Items Needed:

• New 2-pole, 240V Breaker to mount in main load center – amperage to match utility breaker (see specifications Table I for Utility Main Breaker size – should be manufactured by same as Main load center).
• Anchors and screws to mount switch to wall.
• PVC cement (to secure connectors onto flexible conduit)
• Additional wire connectors if switch is “hard-wired”. See Table 2 for correct size.
• May need Arc-fault, GFCI or Surge protection circuit breakers. If Arc-fault, GFCI or Surge protection circuit breakers are used as the branch circuit protector in the main load center, they MUST be used in the manual transfer switch. See Table 3 for compatible breakers.
• Power Inlet Box – for “hard-wired” installations.
• Power Cord to connect generator to switch or power inlet box.

Q: Just ordered a Generac GP 17500 watt from you. Can you advise what manual transfer switch is used with this model for maximum performance?

Thank you!

by Tanya from Pennsylvania on January 04, 2012

A: Any 50A manual transfer switch will give you a maximum of 12,500 watts which is the same for the generator you purchased. The Generac GP17500E has a 50A outlet for its largest output which provides a maximum wattage capability of 12,500 watts. (Amps x Volts = Watts).

Good Switch With Some Limitations
I have this switch on my main house panel and a full size 30A Reliance X series on a sub panel at the back of the house. The Gen-Tran works as advertised. I have a newer model, and the watt meters are on the right side. While larger than some transfer switches, it is still much smaller than a common entry or sub panel.

The breakers that come with the switch are a mixed bag. There's a block that has 4 slimlines, a single breakers for 20 and double size 30 amp & 50 amp 240 circuits. If you... more
