Rated 4.5 out of 5 by 34 reviewers.
Rated 5 out of 5 by Simple - Peace of Mind Very easy to install. If you are comfortable installing a breaker, you can easily install this whole house surge protector. It took about 15 minutes to install. I had to move two breakers down the panel so that it could be as close to ground as possible. Given the number of computers and electronic appliances (fridge, stove, microwave, water heater, dishwasher, furnace) installing a whole house surge protector is a lot cheaper than replacing appliances or having them repaired. (Note, I still have my surge suppressor strips in place ... just in case.) May 21, 2013
Rated 5 out of 5 by Very easy to install A surge protector was suggested by the furnace repair guy.I contacted Wi. Public Service for information. This one meets Wi. code. It quickly snaps in and one wire to ground. Install it as the top breaker and keep the pig tail short as possible. Now my house is protected. I also use surge strips as recommended for more sensitive electrinics January 30, 2012
Rated 5 out of 5 by Whole House Surge Protection The product installs easily and works as advertised November 4, 2014
Rated 4 out of 5 by First Line of Defense If you've got a Square D QO panel, you should have this surge breaker installed. It is the first line of defense against surges that wreak havoc on electronic circuits that are in everything from your toaster, coffee pot and refrigerator (120v) to your clothes dryer and oven (240v); this catches it all. You should still have a computer grade surge strip for your computer and AV system, but this will take care of everything else. December 24, 2013
Rated 5 out of 5 by Great for flush-mount panels. This is one of those devices that you don't notice working. You just notice when it fails. But if you have a flush-mount panel, and want whole-house surge protection, this is the only way to go. Installation is easy - if you can install a breaker, you can install this unit. You just turn off the power, attach one wire, and snap it in. Turn the power back on, remove the two blanks where the device will be, and close it up. As long as the indicator glows, everything is working. You should check the unit once a month, and after storms, to be sure it is still working. This unit will be your first line of defense. It does not eliminate the need for surge protectors at your electronic devices. They provide your second line of defense, as well as protecting from surges generated by other devices on the same circuit. One drawback with using this device is that you have to get the proper one for your panel. It is not a one-size-fits-all device. If you do not have a Square-D QO panel, it is not going to work for you. It is not going to work with a Square-D homeline panel. There is another model for them. October 5, 2013
