Review on Square Schneider Electric QO2175SB SurgeBreaker by Jacob Guerrero

Excellent. I turned off the power to the panel. Then just unplug the 2 existing switches and slide them down and screw them back on. Didn't even have to unplug it. Then I inserted this bracket into the free space at the top of the plate. Then I only connected 1 white wire. Put the cover back on the control panel and turn the main power back on. Green light required. Installation is very easy and it is enclosed in my panel compared to other devices that would require a different enclosure outside of my panel box. I then added a new surge protector to each of my TVs as recommended for layered protection. Very satisfied.
