We lose power in our neighborhood all the time. I wanted a nice, neat, clean way to transfer the entire house from utility- to standby power with the flip of a single, well-located switch, preferably at the point where I plug in. I found this item at Homedepot.com after several tries to do it with separate components. Each time, I was well north of $300 for parts alone.
Everything I wanted in was in one complete package: a WX-covered L14-30P twist-lock power inlet, 100A main- and 30A Generator breakers with mechanically-coupled safety interlock to prevent utility power-line back-feeding, and the capacity to power my entire house with one single connection, all in a code-approved outdoor enclosure so I could mount it right next to my meter. While I can't power everything at once, I can still power anything I need.
THe City inspector was so impressed by how this connected, and wanted to know where to get one for himself!
Someone at Square-D was definitely thinking with this one. Some Home Depot stores actually carry this item in stock, making an impromptu installation possible DURING a power outage if necessary.
Great job Square-D AND Home Depot!

HAVING THE TWIST-LOCK DEVICE MOUNTED IN THE BOX IS VERY CONVIENENT

Rated 4.0 out of 5.0 by Kgeo Very good but......
Quality product. Well built and able to do the job but not so well thought out. I needed to feed a sub panel which the panel does but getting #2 -100 amp wire around and beside the generator plug is not so easy. I needed to come through the side wall knockout to attach to my main breaker box and the generator plug is right in the way. The knockout is supposed to be 1.5 inches but is made in a way that it really is not that big. Panel works fine but could have been better designed.

The QO 100A with 30A Generator manual transfer switch works good as and in and out manual trasfer switch when you need to take over te complete load or as a transfer switch with load center when you can only support selected devices. Plus with a 30A twist lock receptacle it makes hooking up the generator very easy. I wish they made a similar product with a 60A receptacle and more circuits in the load center portion. Great product.

Rated 5.0 out of 5.0 by JWB2 Well worth the value
A great innovation in transfer switches and worth the money. I would like to see the outlet as an option. When you are mounting this unit inside and installing a remote outlet the one on the panel is not needed and a panel made for indoor use would be great also (but that might be asking to much) still a great product and well worth the price

This switch has a great price, it seems as thouigh it was a small breaker box that SQ D converted to a transfer switch. It does have the means to do the job and it does hook up fairly easily. Just a few changes in design would make it an exceptional value.

Rated 5.0 out of 5.0 by Kipperdog Great Little Transfer Switch
I bought a portable generator to provide power during a power outage. What a hassle running extension cords all over the house. I investigated transfer switches and saw a few interior "kits" ranging from $300 - $400. I wanted something exterior that would sit right next to my house panel. Somewhere on the internet someone mentioned that they bought this panel at The Home Depot and sure enough, there it was. This is a very cool device.
Someone at Square D was thinking. They took a standard 100 amp 120/240 VAC load center and added two mechanically interlocked 2 pole 100 amp and 30 amp breakers,. Then they threw in a 30 amp twist lock plug with a flip cover. Nothing else to buy. All for about $130.
I spent another $350 in pipe, wire, circuit breakers and misc stuff (straps, LB's, grounding bushing, etc.). Installation is not for the amateur (I am not an electrician, but I play one on TV). I only had one problem and it had to do with grounding. The frame of the generator is considered adequate grounding for anything plugged into the generator. However, once you "plug" it into your house system it must be grounded. Rather then tie it to your panel's ground, which probably has a bonded neutral, I drove a ground rod for an isolated ground. If this all sounds like mumbo-jumbo, call an electrician.
