Rated 5 out of 5Â by Joe1978 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 5Â by PatD 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.

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.

Not at all sure what the reviewer who said that the template did not work was referring to..
If your panel is one of the ones that this kit is made for, and if you apply the template at the FRONT of the panel and drill where it says, you can't go wrong.
Once drilled as instructed, the rest is a cake.
It has to -- Underwriters Laboratories would have not listed it if it weren't working properly.
Yes, I share the sentiment of the reviewer who said that the price for something like this should be $15, $18 at most, but it is what it is.
Surely beats paying $250 or more for an 8 or 10 circuit transfer switch that doesn't even let you power everything. With an interlock, you get to choose what to power up, and you can turn on the whole panel if you want to, and if the generator allows.
