Answer: 
Since GE is a different brand than a Cutler Hammer (and CH has two types of panels brands), I can say with certainty that this interlock kit wouldn't work.
You'll need to find out the type of panel you have (the older CH or BR type) and find it through Cutler Hammer.

THE INSTRUCTIONS CITE A 2 POLE BACK-FED CIRCUIT BREAKER. IS THIS JUST A REGULAR CIRCUIT BREAKER THAT YOU'RE FEEDING BACKWARD OR IS IT A SPECIAL CIRCUIT BREAKER. IF SPECIAL, PLEASE PROVIDE THE G/E PART NUMBER. i CAN'T LOCATE ANY CIRCUIT BREAKERS THAT ARE DEFINED AS "BACK-FED""

THANK YOU

I ordered the part but the box says that it is compatible with TM3220CCU(P). What does the (P) stand for? See picture below...

Answer: 
Hi Dave,
Thank you for your question.
The MFG did confirm that It will work on that unit….the “P” is just an internal number that has to do with retail packaging.
Hope this information helps.

Rated 4.2 out of 5 by 46 reviewers.
Rated 1.0 out of 5.0 by Poorly designed by GE I just bought and installed this interlock on my GE Powermark Gold LoadCenter, ( 4-handle left-right mains), meticulously following the instructions (though they are barely useful). The install actually was very easy, but when I put the front cover back on, the tabs for the main breaker(s) and generator breakers just don't properly engage. I was readily able to turn on the backfeed breaker while the main was still energized (no, there was no generator connected). I was SURE I had done something wrong, but if I did I can't figure out what it is. Exhaustive research online has turned up nothing, I expect an interlock to absolutely, positively lock out the alternate power source. This product really doesn't do that. It's really appalling given that it is GE designed and made for use on a GE panel. I'm thinking that my only solution is a an aftermarket product, but they all look so cheezy compared to the GE product. Still, no matter how nicely built, it's not worth much if it doesn't even accomplish its basic function. This is a total bummer. (Note that my panel is installed inverted for bottom feed line power.)

Rated 5.0 out of 5.0 by Worked Great. Found this product online and it was cheaper at Home Depot. It was easy to install with the instructions that were provided. August 16, 2016
Rated 5.0 out of 5.0 by Interlock kit If you are installing portable generator transfer equipment, interlock kits are a good way to accomplish a safe reliable means for transfer, without other equipment. The installation instructions are very clear. Be sure to properly label everything and secure an electrical permit prior to starting the project. August 2, 2016
Rated 5.0 out of 5.0 by Great inexpensive way to backfeed legally! I went looking for a 200 amp main load center to replace my out dated unit. I stumbled across this little guy and grabbed it and a new GE Gold load center. The added advantage to getting this, is any unit you install it on can be installed upside down, as all breakers including the mains, are side to side. (advantageous to me, the mains come in on the bottom, and house runs go out the top.) I live in Florida, and this is a 100% to code legal means of back feeding your panel during outages. (my fingers are blocking my name and phone number on the panel in the pic attached) December 13, 2012
Rated 5.0 out of 5.0 by Excellent product. This is a great product for those who want to install a generator inlet box on the outside of there home to feed power to your normal GE PowerMark electrical panel during a power outage without the need for a separate generator panel/transfer switch. This locks the main breaker in the "off" position while the breaker for your feed from the generator is in the "on" position, and vice versa. This ensures that you won't have power coming to the panel from 2 different sources. In other words, this is a very inexpensive alternative to the transfer switch/generator panel. This is a nice kit. It seems well built of quality materials. Don't be scared by the hole drilling, the instructions are very clear and the kit comes with a template so you won't mess it up. Unlike the similar kit for Siemens panels, this GE kit does NOT waste any valuable circuit breaker slots. I highly recommend this product. September 2, 2012
Rated 5.0 out of 5.0 by Great Part This part works great well worth the money. Simple to install with normal tools. December 19, 2012
Rated 5.0 out of 5.0 by Great buy Was looking at all different kits from independent manufacturers and sources and decided to see if a factory kit was available and they were and Home Depot sold them for less than any of the others I had found. I ordered the kit and had it within a few days. I picked it up at the local store here in town without any extra shipping charges to pay. Great job Home Depot. December 22, 2015
Rated 5.0 out of 5.0 by Works great, just overpriced Works great but is overpriced.But that is true with the industry. January 5, 2016
