whole house surge protecters

whole house surge protecters

PostBy: Coalfire On: Sat Dec 17, 2011 6:13 pm

Do they work, inlaws had someone hit a pole out in front of there house took dow two more and a transformer, anyway when the power came back on they found out there furnace, cable boxes, and one flat screen tv were fried.

I have seen those KWR devices that claim they also double as a whole home spike supressor, question is do they actually work, will they protect anything? Do they ever go bad?


Thanks, Eric

Tom says Cutler Eaton is the only surge protectors he'll use something about how its integrated into the bus with circuit breaks.

I always see them on the HGTV shows, they seem to always put them in the Fuse boxes on all new Electrical Upgrades/installs.

CL&P installed one on my meter and several for individual electronics, the whole deal was 70 bucks.

Siemans sels one that goes in their Main Dist Panel. I think its a good idea. Next time I upgrade my panel, I'll put one in.

The guy who drilled my well and installed the deep well pump, 34 years ago, installed something that looked like a big capacitor. It was a cylinder maybe two inches in diameter, 1 1/2 inches high, connected through one of the standard knockout holes of the panel. He said since his company started putting those in, plus a bare ground wire all the way down to the pump, they had no more pumps knocked out by lightning. As I recall it had two wires, one to each 120v leg, plus one wire to ground. So obviously whatever it did affected the whole house, not just the pump. Was this maybe a primitive surge protector? It did not strike me as being big enough to absorb any substantial surge, certainly not a lightning strike. :?:

Tom is my electrician E1, he just happened to be over finishing some work on some panels and generator. His brother is also a master electrician and he mentioned the side knockout device but tom says those work well for wells but not as good as the ones that go in the circuit breakers for whole house.

I've got a Square D brand circuit breaker panel. I installed their surge protectors in the panel after having repeated problem with lighting frying my electronics. No problems since. Carefull analysis of your exterior wire runs outside your house is needed. Ideally you want a surge protector at your A/C compressor, well pump and any outside outbuilding feed panel.

I believe they do have a life. Each time they suppress a surge they give up a little of their life. The only thing is, I do not know how to test them. I think some of the better ones have an idiot light that tells you if they are working or bad.

Wish I had one, lost a well pump and freezer due to lightning. Have a pear tree close to the house that be struck at least 3 times in the last 10 years, it thinks it's a locust tree. Don't know which power companyyou have but might consider one of these http://www.theenergycoop.com/mainNav/el ... rLink.aspx if you need a generator port too.

How long ago was this? What was their criteria for individual electronics? Does the meter have a special marking to know that you have it all ready? Maybe I should give them a call, $70 really isn't too bad.

It makes sense that a larger device would work better. But for the small knockout unit, how does it "know" it is protecting just the well pump? My understanding of electricity is, if the device is connected in the breaker box, then effectively it is covering the whole house because every circuit comes back to the breaker panel.

Dont know but he was also saying how the knock out ones get the wires put on the same hole as the main feed and thats not good because the wire is smaller and can come loose vs the ones that go on the circuit breakers and are directly attached to the bus.

He said 90 bucks was the last one he did so for that i would do it so if you have the space in the panel.

He also told me why they put my ground on closest path to ground on the domestic water instead of just any close cold water next to the panel.

warning the following is horrible.


There was a man in ct a few years back who had a panel on the side of his house and he accidentally backed his car into it. The impact blew out his trunk and somehow sent a surge thru the house. When he walk into the house to tell his wife he found her dead in the tub. The current travelled thru the entire house until it found ground.

I think about two years ago. We had a surge that ate the refrigerator and the wife called CL&P to complain and they set it up. The whole house unit they pulled the meter and installed it placing the meter on top of it. It is about 5-6" deep and has a light on the side telling you it's working. With that installed, they left some serious commercial grade surge protectors with power strips for electronics. I think six or so and some smaller stuff.
