CUSTOMER REVIEWS

Rated 4.3 out of 5 by 40 reviewers.
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 4.0 out of 5.0 by Does not fit 200 amp panel Purchased this to install into my main panel, it does not fit my GE 200 AMP 20 space panel. It appears to be for smaller sub panels only. June 2, 2015
Rated 5.0 out of 5.0 by 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. October 11, 2013
Rated 5.0 out of 5.0 by Works as advertised You will find these advertised on many other websites. This is the cheapest place that I've found, made by the folks who actually make my panel, to allow you to backfeed the whole panel. I didn't want to mess around with a transfer panel. I wanted the flexibility to be able to power any circuit in my home. Install was quick and as-advertised. April 14, 2015
Rated 5.0 out of 5.0 by 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. January 22, 2011
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 Original Manufacturer Part This is a generator interlock kit manufactured by GE, not a aftermarket pieace. This actually holds the genenerator breaker in place for back feeding purposes, as required by code. March 3, 2015
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
