Customer Questions & Answers

Whole house, or individual ciruit?

One of the answers here makes this a bit confusing. Is this a whole house solution, or does it only protect the two individual circuits? "Hi JackOfAllTrades, This surge breaker is intended to surge protect two individual 120 Volt circuits. There is not an option to tie the handle together and service a 240 Volt circuit."
Asked by: PAShopper
Everything on the panel it is connected to.

Does Siemens make a 15 amp surge protector? Why is this surge protector better than just a breaker?

Asked by: bubba
Because its a breaker ( actually 2) AND provides surge protection for everything on the box, not just the 2 circuits its attached to. I am sure there are more expensive ways to obtain whole house surge protection, with more sophisticated units, but for under $100.00 this seems good to me. I am also keeping individual electronis items protected with individual surge protection. Thus I have 2 stage surge protection.

Are you supposed to connect two existing 120V circuits, or one 240V circuit, to this device, or do you just leave them empty?

I noticed in one of the product reviews that someone attached their kitchen outlet circuits to this device. Is this okay, or is it supposed to stand alone on the bus? If my local Home Depot had one in stock for me to look at, I would just simply read the packaging, but since that's not the case, and the information I get online doesn't touch on it, I'm forced to have to ask the question here.
Asked by: JackOfAllTrades
Per the instructions, you can leave them empty.

Will this fit a GE Panel?

Asked by: Gunner
No, this will only fit a Siemens or Murray panel.

The Siemens (Model # QSA2020SPDP) was easy to install and took less than 30 minutes. Two things that I really like about this device is 1) the circuit breakers will trip when surge protection is lost 2) installing these provides surge protection for the whole house.

This one is especially nice because you don't lose 2 spots in your panel because it is both a breaker and surge protection.

My product arrived by UPS an hour ago, and its installed and fuctional already, and that includes opening the box, and the plastic hardpack case the surge protector was packaged in. I cant comment on functionality, but i will assume it will do what it is suppose to do. I can only comment on installation, which was simple. One cavet- You will need to have some basic understanding of electricity and some basic mechanical common sense. After all you will be accessing the inside of your electrical panel. If that scares you, hire someone or find a friend with the capability. I was a little worried that the size of this unit was going to be larger than the combined size of the 2 breakers it will replace ( and hence be a problem fitting it on the bus, and then replacing the panel. And I would say it is "a tad" larger BUT it did not inhibit installation at all. Being a brand new unit, it took a bit of "gentle force" to get the 2 sets of black side contacts to slip over the power side bus bar, and in fact I had to pull back the 2 single 15 A breakers on its opposite side to seat the new surge / breaker. Then I snapped back in the two 15 breakers. The panel cover fit right back on without any problem. One very nice thing about this is that not only does it add whole house surge protection, it also replaces 2 adjacent breakers. My breaker box was full and I had no room for any additional breakers, but you do not need extra room. I thought i was going to need to buy a few 1/2 wide breakers to replace full width breakers in order to make room for this. I saved a lot of $ not having to do that, AND I now have two, 20 A "back up" breakers if I ever need them (great, where do i put them in a small condo with limited storage for "garage type" items!). Note: breaker boxes are unique to the manufacturer. This unit is for a Siemens box. It will not fit a GE style box, etc. I think it does overlap a few styles but make sure to check before you buy. Otherwise it will be like buying a part for a Ford and try to install it on a Chevy. And its more than just a physical fit issue. It also has to do with how the different manufactures connect the breaker electrically to the panel. Imagine trying to plug in your US style hair drier in an outlet in Germany!

Rated 5 out of 5 by from Very nice if you don't want one hanging outside the panel. Perfect solution to having a recessed panel in a finished room. I will have to admit that I am an electrician, but it was an easy install. If you are not confident on what you are doing, please turn off the main breaker. Remove two 20 amp single breakers, snap in the surge protector, replace the wires from the old breakers and turn on.

Rated 5 out of 5 by from 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.
