Rated 4.8 out of 5 by 47 reviewers.
Rated 5.0 out of 5.0 by A piece of mind Install was a breeze, but I had to move some breakers around to get the double pole breaker for the HEPD close to the main 100 AMP main cut off switch. This should be done so that the HEPD catches the surge before it reaches any other breaker below it. I kept the wires coming off the HEPD short as possible, as they explained in the documentation. Could not be happier with this product, but time will tell if something ever happens. I would not recommend installing this yourself if you are not comfortable are familiar of what you are doing. If not call a qualified electrician. March 23, 2014
Rated 5.0 out of 5.0 by I think it worked already. This unit has no indication that something has happened. But, my neighbor had a lightning strike between his well and the garage. It fried his well pump($350) and his TV($400) in the garage. My house did not have any problems. The two LEDs are still green. I had to move and add some breakers to install this HEPD as close to the Utility side as possible. I saw another review where the guy installed this on an existing circuit. The manufacture recommends that this is installed on it's own breakers, 20A. That's what I did. Do not add pigtails either. July 3, 2013
Rated 5.0 out of 5.0 by stops motor surges Once I made sure that my house electrical system was properly ground as well as bonded, I installed this unit, and it was easy. Just follow the instructions and I would recommend that you go the double pole breaker route so you protect both sides of your breaker box and do not forget to twist the black wires with each other. It was also easy to tell that the surge protector was working by turning on a large motor (like a table saw or large air compressor) and seeing that the lights no longer flashed throughout the house upon the motor start up.

Rated 5.0 out of 5.0 by HEPD can be an easy DIY job...every home owner should install this device. Simple installation. Hardest part is figuring where to mount the EPD. It is very easy to mount to the bottom (or side) of a surface mounted service box, but if the service box is embedded in a wall, you will have to open a portion of the wall, cut a hole through the wall stud and run conduit to enclose the wiring. Bottom line: Surface mounted service box hook up is a fifteen minute job. Recessed service box will take at least an hour and require additional parts. December 23, 2014
Rated 2.0 out of 5.0 by this product may not be for the novice do it your selfer. I had to contact square D several times for clarification of instructions. Easy to install inside the breaker panel. Don't know how good it is till I get a power surge. I guess. June 9, 2015
Rated 5.0 out of 5.0 by Layered protection This device protects everything on all circuits connected to your panel, including those devices you typically could not use a surge protection power strip with(washers, dryers, refrigerators, stoves, lighting, etc). I used this in a layered approach. The whole house is protected with this surge protector, then expensive electronic equipment also has a surge protecting power strip. The unit is very easy to install. Simply remove a knockout on the panel and push this device through the knockout hole. Attach the nut to hold it firmly in place. Wiring is just a case of feeding the two black wires to each hot pole of a double pole breaker, and the white wire to the ground bar. It takes just a few minutes to do. The device has two LEDs, one shows it is powered up, the other shows the status. The top LED should always be lit, the bottom LED will be lit if it is working, and unlit if it needs replacing. This device protects your household equipment from internally and externally generated surges. If you can change a breaker, you can definitely install this device. With a limited warranty of five years with a $50,000 connected equipment warranty, it is inexpensive piece of mind. July 1, 2013
Rated 5.0 out of 5.0 by Great Product, great price My panel is set into the wall so there was no way to mount it on the side of the panel, but I had no trouble setting in to the bottom of the panel case and wiring it to the breaker. Make sure you have room for another breaker spot to add a double or single 20 amp breaker. There are usually only 7 or 8 slots that will accept a double breaker. May 6, 2015
Rated 1.0 out of 5.0 by Waiting for lighting strike Won't know until we have a lighting strike if it works. May 12, 2015
