EATON CHSPT2ULTRA Ultimate Surge Protection 3rd Edition, 2.38 Length, 5.25 Width 7.5 Height

Instructions are clear, and install is straight forward. 60 Amp breaker recommended but not absolutely required. Unless your protected home equipment survives a lightning strike or you have monitoring equipment it is difficult know if or when a surge suppressor has successfully performed its function. Only time will tell.

If you live in a summer thunderstorms state like North Carolina - you would be pretty ignorant not to have this device installed at your main electrical breaker box. After I lost my TV and a few other valuable electronics/appliances one night after hard thunderstorm - I had a conversation with my electrician. He said that he installs these for people that learn it a hard way like myself or anyone that cares for their investment. Very easy to install but dont try doing it yourself, unless you are in a construction trade and comfortable doing it yourself. It can get pretty dicey if you dont know much about electrical work!

Unit is as described, after watching several You Tube videos I did the installation myself. Nothing I would recommend unless you are VERY familiar with an electrical box. Installation was easy, just add a 50 AMP double poll breaker and connect the wires according to the instructions. Other than the green lights are, I dont know how to tell if it is working, but out power has not gone out sine installation. I guess that is proof its doing its job.

just what I needed

Great product, great price.

We live in an area covered by Puget Sound Energy, a notoriously un-reliable source for electricity. After frequent brown-outs and outages, and blowing control boards for electric stoves, washing machine, and finally a refrigerator, it was clear that the seven UPS units we have for computers and audio-video equipment wasnt enough - we needed protection for the whole-house. This unit was rated well, and was not difficult to install. In the two years weve had it, we have not lost any appliances to a PSE power glitch. And its not because the quality of the power has improved. The visual indicators are easy to see, and when the unit requires replacement, it wont be tough to tell. For maximum effectiveness, youll want to be sure that the unit is wired to its own circuit breaker which is placed as the closest breaker to the feed from the street. Keep the wires to the unit as short as possible (mount it directly to the side of your breaker box). This is all explained in the instructions, with more details on the web.

Easy to install

All of the above and great service and delivery

Update 2023: The SPD is still working. No problems. Original review: Theres a lot of things about this surge protection device to like and dislike. As long as quality control is good for the internals, I believe its a great addition to our home. But its very quirky in the design elements that make installation in a retrofit a nightmare. Our panel is pretty typical. Its mounted between two studs, which forces all electrical wires to enter from the top or bottom. The service entrance wires enter from the back. Unfortunately, the service entrance does not have a service disconnect, nor any breakers. This means that I am forced to find a way to 1) bring in the spd wires through a 2x6 stud, or 2) extend the wires like another reviewer did. Because a top or bottom mounting is too distant to catch surges before they effect the wires of each load in the load center. I chose #1. First off, I ended up rewiring my entire panel, a feat that took about 7 hours (sorry honey). This was an unexpected consequence of the poor planning of the previous owner and me wanting to finally have a breaker panel that could be easily worked on during remodel efforts. After that ordeal, I attempted unsuccessfully to figure out a smart way to mount the spd. Its plastic on the wire end and has a modified threaded nipple for 1/2 or some call it 3/8 connection to a panel knockout. In all my searching, I never found a way to just extend this to the panel using, say, a piece of conduit. I tried. And gave up. So at the end of the day, I just cut the stud butted up against my interior panel. {Maybe a tiny metal box with knockouts would have worked, but then only if I had chosen a knockout further back in the panel.} I cut a huge slice out of the stud to mount the spd directly to the panel with a locking ring. That was not an easy task, but I do this kind of thing for a living. YMMV. But it actually gets worse. Once I got the SPD in there and all the wires twisted and connected to my 50A breaker that I had placed at the top right spot in my panel, I thought my woes were at an end. But I hadnt noticed a teeny bit of detail: the spd is so close, there is no way for the panel cover to fit. The knockout I had chosen placed the spd proud of the drywall and, because there is no known way to extend the little plastic nipple, right in the way of the panel cover. At this point, all I could do is grab a grinder and jigsaw, cut a big slot into the thick panel cover, and then file the edges smooth. Now because of all this work with cutting in a spot inside an exterior wall, theres insulation and drywall finishing to consider. I have yet to deal with all of those issues because I am remodeling this area anyway. But expect things to be time consuming. Furthermore, an inside-the-wall spd means that the drywall will need to be replaced with a closer-fitting piece than the one that the installer hacked into to do the rough-in work. People: if you have an interior panel... Just hire a professional, set up a camera, and enjoy watching someone else figure this out. If your service entrance is outside and in the clear... Go for it.

The concept is this surge protector will protect all appliances in the house - washer, dryer, TVs, computers, etc. It was installed by a licensed electrician. You just have to check inside your breaker box occasionally to ensure it hasnt tripped because once it does, it needs to be replaced.
