Rated 5.0 out of 5.0 by theBestStuff Best Circuit Breaker Style Whole House Surge Suppressor on the market
This is the best circuit breaker style plug in whole house surge suppressor on the market. The clamping voltage is 500V which is 100V lower than most other whole house surge suppressors. Most manufacturers try to explain that it is important to keep the leads, if any, as short as possible between the connection point on the electrical panel and the surge suppressor, but most manufacturers also fail to explain what will happen if you do not. There are no leads on circuit breaker style surge suppressors. Circuit breaker style surge suppressors are also called integral surge suppressors. See the picture below from a document called TVSS_wp1.pdf that I found on the internet. Compare the Green verticle bar for Probe #2 (surge voltage at the wall outlet) for an integral surge suppressor to the Yellow (3 feet of 6AWG connecting leads) and Blue (3 feet of 10AWG connecting leads). 3 feet of 6AWG connecting wire will double the surge voltage that gets past the surge suppressor and 3 feet of 10AWG connecting wire will let 2.5x more surge voltage get through to your appliance.

Rated 5.0 out of 5.0 by Bob Excellent fit in a standard 200A panel.
This breaker unit just clips right into a standard 200A breaker panel and just like the description says - it takes up two breaker slots so that it can connected to each phase of the typical residential service.
The hardest part of the installation was finding a place to tie it into the neutral/ground bar. Many of the screws in the neutral/ground bar in my breaker panel were seized :-(
Make sure that after you install that you turn both breakers ON and that the green lights come on for each leg otherwise you won't be protected!
For those with double breakers in a single slot (like most of mine are) this unit is just a single breaker in each slot so don't expect to just remove and replace a couple of double breakers with this unit since you will need two breakers for each slot to reconnect your existing circuits.
I think the hardest part for me will be to check this breaker every time we have a power failure to make sure that it is still on on both legs since I currently don't have any circuits connected to it.

Rated 5.0 out of 5.0 by MTK330e Love this product as a contractor and a consumer
Traditional whole house surge protectors are mounted on the exterior of the panel which can be difficult when panels are flush mounted. Also in the event a panel is loaded with circuits traditional protectors require a dedicated 2 pole breaker to connect to. Great product and design. Slipped right in like any old breaker and made my job easy.....hope this helps
