Customer Questions & Answers

Will this interlock work on a TM3220CCU load center?

I ordered the part but the box says that it is compatible with TM3220CCU(P). What does the (P) stand for? See picture below... Thanks!
Asked by: Anonymous
I have the same panel, TM3220CCU, it is printed on the interlock box that it is supported, but this is wrong. I can guarantee you that it does NOT work. FYI, I believe the correct part for this panel is THQLLX8FL.

Asked by: rama3953
No, this only works with GE Powermark Gold panels. You would need a Cutler Hammer interlock, designed for you panel.

Re: 2 POLE BACK FED MAIN CIRCUIT BREAKER

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
Asked by: LRP1
you would use any GE 2 pole circuit breaker sized for your generator output up to the max amps the bus is made for.

The instructions and template provide made it easy to drill the holes in the cover. The kit installed easily within the holes drilled and did the job of making sure the main breakers are off when the power inlet breakers are in the on position. Use care when working within the main load center. Your main wires can still have electricity up to the lugs even if you turn off the main switch within the load center. In my load center the main switch and lugs are on the bottom.

Rated 5 out of 5 by from works like a charm, easy to install. The Interlock kit is far less expensive and easier to install than a transfer switch. Plus, it is much more flexible since it allows selection of any circuit (within reason) in the main panel instead of having to pre-select circuits and wire only those to the xfer switch. The caveat of course is to ensure that the load placed on the generator does not exceed its capacity and the capacity of the generator's main breaker. So careful load analysis, load balancing, and panel labeling should be done prior to any emergency. Also note that the safety protections provided by the Interlock are not in effect when the panel cover is removed.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Time And Money Saver! When you want to install a hook up for a portable emergency generator, the installer will try to sell you a very expensive ($300+ depending on the number of circuits) sub panel and interlock switch. That's the old way of doing things. It also takes more time to install and that is even more money. Interlocks have been used for years in industry to isolate and control the flow of energy and now makers of home load centers are catching up and creating items like this that install right into your panel and allow you to energize any and perhaps even all of your circuits without the need for a subpanel where you have to pick and choose what to power. The interlock fits over your main breaker and also around a new generator breaker that you install just above it (in the case of this item). It is designed so that both of these cannot be in the "ON" position at the same time and prevents back energizing of lines when the generator is running as well as back feeding of the generator when the main power is restored. Definitely a better, simpler and more elegant approach! My house is mostly natural gas and my 8kW generator can power the whole shebang. But we had 15 circuits for all the rooms installed in our GE Powermark Gold load center. This lets us power the whole house for a fraction of the cost of the transfer switch option. A warning though, a lot of electricians I talked to do not understand these units because they are used to working with old fashioned transfer switches. Some even refused to install it. We found a guy who was knowledgeable and charged right around $500 for the work including all other materials and took 3 hours. Our quotes for transfer switch installs were all over $1000. Definitely worth the couple bucks this cost.

Still, expensive for such a small, simple product. The arms of the interlock had to be bent into a flatter position using a vise and some muscle otherwise the breakers that were supposed to be locked out could be engaged by flipping them under the metal tabs that are intended to block their movement. Installation was simple. The template provided for drilling the holes to mount the interlock on the breaker panel cover was of good quality. The instructions were not clear as to where the washers and lock washers were to be installed. The provided diagram only indicates the use of 2 non-locking washers.

Rated 5 out of 5 by from Great idea Easy to install. Whole lot cheaper than a transfer switch. Do your homework to make sure the lockout kit is compatible to your load center.

Rated 1 out of 5 by from 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.)
