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

The instructions were easy to follow. Confession: I promised a friend of mine who is an electrician that he could put it in because he needed the money, so being a man of my word, he did the work while I watched. This is also good should I ever need to make a claim for damage, because the instructions state that the installation should be done by a qualified electrician. Really, anyone who is handy around a breaker box could do the job. Its just a matter of turning off the main breaker to avoid possible electrocution, popping out a knockout, installing the unit and hooking up a few wires. Anyway, from what Ive read it should provide good whole house protection and that is worth a lot!

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.

Easy to install. Manual suggests a 50 amp breaker for full protection. The wiring is too small a guage for 50 A. I had a electrician come by for something else and he agreed.

This product is a great safety device. The installation was simple and straight forward. I like the led lights on the face that indicate its status. I hope its never needed but its there if needed. Dont forget to buy a dual 50 amp breaker to go with it for installation.

State of the art in surge protection. I had several electrical surge after the installation and all is working in perfect condition. Before this surge protector I had several outages and burned more than 5 smaller protectors

trusted brand, but pigtails are kind of short. had to make an extension with heavy gage wire. would be nice if the cover would come as accessory.

Works as it should.

Item as described. Arrived early. No issues.

Primary issue - Eaton requires a 2 pole 50 amp breaker. Minimum wire size for that breaker is 6 awg. The 14 awg on the surge protector are too small unless you modify them , which voids the warranty. . Secondary issues - The two hot leg wires are a shade under 15 inches. The neutral and ground wire are 16.5 inches. This is not published in the specifications. That’s about a inch less than I needed for the hot wires. Measure your system carefully. If your panel is in a stud bay instead of on the wall, especially if it’s a tall panel, you may not be able to use this item
