Rated 5 out of 5 by Excellent Product--Easy Installation--Good Protection For once in my life, I "lucked out" and actually possessed the "right" thing in the form of having the "correct" service box in which I could use this particular product. Normally, things seldom go that way. In this case, Siemens has created an easy-to-install INTERNAL Surge Protection Device--which, as most folks know, one cannot simply install just any old circuit breaker type component into just any service box. The manufacturers, generally, have to match--and such was the case for me. Home was built in 1995, and the electrician installed a Siemens 200-amp service box. One day recently, I went browsing on the Internet for a "whole house surge protector" when I stumbled upon this particular device. Sounded exactly like what I was looking for--and seemed easier to install than that of the other types that mount externally. While total power absorption (of this internal device) is less than that of most externally-mounted devices, ease of installation and "value" won out in my decision to choose this particular device. Therefore, I checked the make/model of my box (just to be sure mine was built by the same manufacturer), and lo and behold, it was. Bought this circuit breaker via Internet, and had it a few days later. I had actually never removed a circuit breaker before, but a few searches on the Internet yielded some good "how-to's". Further, I had several adjacent 20-amp breakers to choose from, so I isolated those circuits (and removed the panel cover) and removed the old breakers using what I had learned from the Internet--while also employing (reasonable) safety precautions. I did not secure power to the entire service panel, and even if I had done so, I knew certain bus components would still be energized even if I had secured power to the whole box. I used my Fluke to test areas--both before isolating my two circuits as well as adjacent areas I suspected would remain hot--so I knew where my "boundaries" were. I must say, it was incredibly easy to remove and install circuit breakers once you understand the physical mechanics involved. The Siemens 20-amp Surge Protected Circuit Breaker installed perfectly in the space vacated by the 2 20-amp breakers I removed. I connected my circuit's hot leads to the new breakers, and installed the neutral pigtail (integral to the new protector) to an available termination point on the neutral bus bar (cutting the wire first to keep the length minimal per directions that came with the protector. The directions were simple, adequate, and easy-to-follow, and the device fit perfectly in my service box. Switched on the circuits, and saw the green LEDs illuminate--thereby signifying protection was active. Removing the panel cover, removing the old breakers, installing the new surge protector, and wires, as well as re-installing the panel cover took less than 15 minutes. This was one of the easiest and most effective (I hope) "upgrades" I've ever done. To be honest, I won't really know how effective this device is unless it gets put to the proverbial test, but not having anything in place previously, at least, this gives me some piece of mind that some protection now exists. Thanks for making such an easy to use product. April 26, 2014
Rated 5 out of 5 by Excellent product I Received the product in fine time. While I was able to install it myself, I would recommend hiring an electrician. I had to move most of the breakers on one side of my panel to put the surge protector in the correct position. I am assuming that it will work as advertised. July 30, 2013
Rated 5 out of 5 by Nice piece, easy install, best price was HD. This was the only home improvement project I can remember the took the time I estimated - about 10 minutes - start to finish. It could have taken less, but I had to relocate a breaker from one side of the panel to the other, in order to fit this. It should be noted that this is intended to be installed at the service entrance, where the ground and neutral are combined, not at a sub-panel. It is also best to plan on installing it on whatever side of the box the G/N buss is on, as the current dump wire to G/N should be as short and straight as possible. Will it work? Will it help? Who knows! But since my house is on a ridge at about 7,000 feet in the Rockies, where thunderstorms are usually experienced from the inside-out, it sure can't hurt. We'll see. But for the low cost and easy installation (if you have the box space) it's a must-buy. May 27, 2014
Rated 1 out of 5 by DOA The unit was defective. I tried it in two different electrical panels and only one of the protection lights would light so I have decided that it was DOA and will be returning it to my local store. It may still be working but since both lights are supposed to be one indicating protection, I can not trust it with only one showing on. January 19, 2014
Rated 5 out of 5 by Just what I wanted Best price by far and good quality. will be used as main protection for panel. February 25, 2014
