Rated 4.8 out of 5 by 92 reviewers.
Rated 5.0 out of 5.0 by Easy install - safe and legal way to run a portable generator during power outages. Straight forward installation; no surprises. Should take about two to three hours to install if you have a surface mounted panel and surface mount this switch and conduit. I decided to flush mount the switch since the subpanel I was connecting to was flush mounted. I opted not to purchase the flush mount kit; instead I recessed the switch using a 1X backer board. I then brought the sheetrock right to the box and finished it. This is a great kit for the DYIer, as long as you got a basic understanding and respect of your electrical system. July 21, 2014
Rated 4.0 out of 5.0 by READ THIS REVIEW! I love this product, but you need to know if it is right for you. I recommend this unit for anyone who does NOT have a well or has a generator 5000watts or less. Main limiting factor is the 6 circuits. In my situation, I have a 7500 running watt generator (9350 surge) and I have a sump pump and a well pump. I wish I had bought a unit with at least 8 circuits. I had to choose, and I ended up wiring the living room tv / lights, the furnace, the sump pump, the well pump (2 circuits!) and the kitchen fridge. When everything is running, I surge to about 4500 watts (sump takes up 1000). The only reason I dont have lights on in the bedrooms, the cellar, and the bathroom is because I dont have enough circuits. If you have a smaller generator, 5000 or less, this is a good size unit. If you have no well pump taking 2 of the circuits, this still would be a good choice. But for me, I wish I realized how much more Id have liked to have paid $100 more before I installed. All that being said, the unit is easy to set up. I have never wired anything into the circuit box before, and it was easy. Took me about 2 hours, but 1 hour was just planning. And my electric box was installed in 1962. Newer boxes will be easier to wire. Since I have a portable generator with extra watttage, I can still run an electric cord from the generator to run my 2nd fridge, or any other items for an extended power outage, but this will keep my family comfortable during most outages. Heat, Dry Basement, Warm Water, Cold food, TV, Coffee Maker, most lights. Thats what this unit gives me. October 30, 2012
Rated 5.0 out of 5.0 by Great value kit, Super easy install I bought this unit before hurricane Irene. It works really well and makes setting up my 5000W portable generator safe and simple. During the recent October snow storm here in CT, my wife was confident enough to set up our generator when I was gone. I installed this in about 1 hour. The DVD is great and made the installation a snap. I added up the cost of cords, wire and plugs I would have needed to feed my panel through my dryer outlet, and this was almost the same price and now I know its safe and easy to set up. Great product. November 2, 2011
Rated 5.0 out of 5.0 by This product is simply awesome!!!! I installed this yesterday in a few hours. This is the best thing I've ever bought. And it worked perfectly. It's weird to think that I'm looking forward to a power outage! We just got past Hurricane Sandy during which we had the generator outside with a bunch of extension cords coming into the house. Never again with this product! Simply perfect! November 1, 2012
Rated 5.0 out of 5.0 by A must-have if you own a portable generator! This is a perfect solution to having extension cords running all over the place if you have a portable generator. I'm a fairly-skilled DIY'er. If you have a basic understanding of electrical wiring, this should not be a problem for you to install. I installed this in a finished basement, and it took about 5 hours.I probably could have cut that in half in an unfinished area, as I had to cut an opening in the drywall, install mounting blocks, fish wires behind the walls, etc. The wiring is straight-forward - if you've ever installed a circuit breaker, you should be able to install this. Once finished, I connected my generator to it and flipped the switches, and everything ran as expected, except for 2 circuits that were on AFCI-protected breakers (see note below). I had a furnace, a tv, a refrigerator, several lights, and a pc/modem/wireless router running, and I was only pulling ~2000 watts, according to the built-in watt meter. My generator pushes 6000W, so I should be able to run all the necessities. A few notes/suggestions: This transfer switch will be MUCH easier to install in an unfinished area. I installed this in our now-finished basement, which added several steps to the installation (removing drywall, fishing wires behind walls, etc). If you are thinking about installing this unit at some point in the future, plan accordingly if you are going to finish the area before you get to this. I wish I would've spent the $$$ at the time and saved some hassle. This unit is ~4.5" deep, due to an angled "hood" at the top of the unit, so it will not fit in standard 2x4 walls, without protruding out past the finished drywall surface. The unit comes equipped with a metal-sheathed whip that carries the wires over to the breaker box - think about switching this out with an approved, flexible, non-metalic conduit. I had to trim mine to length, and it is not very flexible. If you are going to install the outdoor power inlet, consider using braided 10-3 wire instead of solid copper. Much more flexible and easier to run thru conduit, etc. If you plan on connecting the transfer switch to branch circuits with AFCI or GFCI breakers, the AFCI or GFCI protection will be lost when trying to power these circuits from the transfer switch - my breakers tripped immediately (2 bedroom circuits). To get AFCI or GFCI protection when running on generator power, it must be provided at the outlet instead. (This note was not in my installation guide, but I found it on their website) October 26, 2012
Rated 5.0 out of 5.0 by Great product, really well thought out I purchased this and a 5500/6500 watt generator on Thursday 10/25/2012 prior to Hurricane Sandy arriving. I tested and ran the generator while I completed the wiring of the switch. The instructions were thorough and accurate. The work only took a couple of hours including time to chase my toddler (helper). If you can wire a light switch you can complete this work. The only parts not included in the kit are the 10/3 wire from the inlet plug to the transfer switch and the required cable adapters. Once the storm hit and the power went out it was one pull to start the generator and 30 sec. to flip the transfer switches. I am running on generator power as I type this and have been since Monday night with no problems at all. October 31, 2012
Rated 5.0 out of 5.0 by Great Product After looking at all of the options to power my house during an outage, I decided that I couldn't live with anything that would put the guys trying to get me back on line in danger. I bought this product and installed it myself in a couple of hours. If you have done any wiring at all and take your time, you can do this. Great video comes with the product that steps you through it. I was able to cover about 90% of my house with the 6 circuits provided. Kitchen (including fridge) bedrooms, furnace, freezer, living room, dining room, bathroom and bedrooms. When the power goes out I simply plug in, start up and flip six switches and I'm on line. Literally takes me longer to get my generator out of the garage than it does to get everything set up and running! Due to some East coast storms I've had it going three times this week. My wife got it set and going two days ago with no problem. I'm writing this review powered through this box and my Rigid Generator right now. Be safe and do it right. July 21, 2010
Rated 5.0 out of 5.0 by Easy to install, good features, works well Installation instructions are very good, you will still have to do some work to get it installed properly. I like the features on the transfer switch, specially the current display that allows you to determine if you have your loads balanced from both phases of generator. February 9, 2013
