Rated 4.6 out of 5 by 25 reviewers.
Rated 1.0 out of 5.0 by Poor quality. Two out of three now defective!!! The first switch I installed had two circuit breakers that were broken. Had to return and customer had to wait for replacement. The second one I installed for a different customer had two switches that were broken. I had installed this as a recessed install and had to completely unwire, remove drywall and waste four hours to diagnose problem, remove defective switch and install a replacement. Again, customer had to wait for a replacement and I lost money on the job because of poor quality control :) :) December 10, 2014
Rated 5.0 out of 5.0 by The Only Way To go Have installed over 10 of these or the 6 circuit model. Extremely simple to install and use. If you can flip a light switch, you can transfer power. This is the only safe way to use a generator and not chance backfeeding to the utility. So far superior to running lead cords all over the place. Have never had a problem with them. If your generator has the capacity, go for the 10 circuit over the 6 for flexibility - even if you have to alternate circuits so as not to overload generator- well worth the price difference.

Rated 5.0 out of 5.0 by The Right Switch for the Job. We needed to upgrade our transfer system because we got a new 30 amp generator. Our old system would only handle 25 amps and we were concerned with an overload possibility, This was bit bigger than what we needed but we decided to go with it anyway. At present we have a couple of spare circuits if they are needed in the future. We were fortunate to have our electrician up here doing some more work when we checked this out. He told us that it had everything we needed plus the spare outlets. Installation went smoothly since we had a trusted professional doing it. Testing was flawless. March 6, 2012
Rated 4.0 out of 5.0 by Good Switch Installed today and would say over all it is a good switch. A few things to note: 1. If you have a 42 circuit panel~ keep the whip in the center bottom of the panel because the leads need to be longer. 2. The leads for the plug on the front of the switch need to be longer. Other than those two things the switch is well worth the money. December 11, 2010
Rated 5.0 out of 5.0 by Just installed with help from an ellectrician friend - easy enough to install Well made quality product w/ competitive price and free shipping to home. Set up for back up 7500 generator and can run most of the house; especially for well pump, furnace, electrical outlets, etc. Living in a rural area we have no water on power outages and after last hurricane I had enough ...................tested with no problems. Take the time to label installed circuits. December 27, 2012
Rated 5.0 out of 5.0 by The is a great product I installed this product a few days ago and put it to the test. It works great, i just wish Reliance Controls would have offered a 12 or 14 circuit switch. Overall, the product is a fantastic product! I would recommend the product to everyone. August 24, 2011
Rated 5.0 out of 5.0 by Easy Install The instructions are very straight forward and easy to follow. Wire markings are clear and easy to read. Install took only about 2 hours. However, do not attempt installation if you are not comfortable working around electricity. November 20, 2012
Rated 5.0 out of 5.0 by Good Product at a Fair Price This transfer switch kit is nicely designed. The flexible conduit mounted easily to my circuit breaker box, and the wires within were plenty long enough to route and connect without difficulty. Each wire was labelled along its length with the switch letter (A-J), so wire identification was easy. The switch box switches have a good solid feel, and the power meters are handy indicators of power usage on each phase. Documentation was good as well. I recommend this product for being an easy to use complete and high quality solution at a fair price. February 21, 2012
