Square D HEPD80 Universal Whole House Surge Protection Device, 1-Phase, 3-Wire for 120/240V, 80kA

I was a bit unsure at first, but I’m so glad I got it. My neighbor hosue got hit with lightning so i had to get this. this was a 20 minutes installation. great and hopefully will protect mine in the case. What I really like is how simple and convenient it is to use. Everything about it feels reliable and thoughtfully designed. I’m already thinking about getting another one for our rental house.

had a surge without a surge protector and lost several items a few years ago installed a surge protector and lost that in a recent surge but nothing else so this item is to replace that surge protector i will never be without a surge protector it is very easy to install

Quick reliable and they delivered on time and exactly what I needed

The HEPD80 is a great value to provide some protection for your main electrical panel.The surge protector will also help avoid spikes from an emergency power generator.Most new furnaces, washing machines, clothes dryers, stoves, dishwashwers, microwaves and hot water heaters now have electronic circuit boards that are unprotected from power spikes. We commonly protect our TVs, DVD Players, Computers and other electronic devices that cost less than our major household appliances.The HEPD80 fairly simple to install (if you have any electrical experience). FYI: This job is not for the someone that has no idea what they are doing (I am a journeyman electrician with over 25 years of experience).I have installed several main panel surge protectors over the years. The HEPD80 has a very high rating (80,000 amps) for maximum surge amps. If you ever experience a surge this high, it would most likely be from a direct lightning strike and you will still have some damage. This unit would protect you as much as any other high end surge protector.The HEPD80 has two green lights that tell you from a glance that it is operating properly.If one (or both) of the green lights are out, you will need to investigate for a problem.Problems could range from a tripped circuit breaker, you lost the incoming power feed or that your main electrical panel has taken a hit and your surge protective device did its job and is in need of replacement.This is a fairly compact unit ... and best of all it is MADE IN THE U.S.A. (Yes, that still matters to me).I highly recommend this product!

Previously "Made in US" but not any more. The unit I received which I decoded with a manufacture date of 1602 (2nd week, 2016) is "Made in Mexico." I take points off for that . . . .Rated at 80kA, which is very high, HEPD80 is 2-3x of the push-in breaker space protectors which are easier to install (but those protectors are recommended to be close to the ground bus). For me, my Central AC took up the first 3 breaker spaces (#10 & #12 gauge wire) which couldn't be moved as there wasn't enough wire slack length.This unit, HEPD80, doesn't have any location requirements except to keep wire lengths as short as possible & not to coil or bend wire. Placement flexibility and higher surge rating (but higher cost, and higher initial installation time) seem a better solution.The HEPD80 is connected to a recommended breaker of 2-poles, 20A (2-poles to cover both supply wires) - - I used a new breaker, but I've seem one installer in Youtube just add to an exiting breaker (each wire clamp can hold 2 wires).By coincidence, I have a Square D main panel -- the panel states it's a "Homeline" model (vs. "QO" model which is more expensive) -- bought the breaker from Home Depot which carries breakers for both lines (HD also carry GE, Siemens, etc.).The product description on this site shows a panel drawing -- 2 black wires to TWO adjacent, single pole breakers (but a double pole breaker - 2 spaces - is OK), green wire to ground bus bar and white wire to neutral bus bar (some panels have ground & neutral on same bus). 2 1-pole or 1 2-pole breaker(s) to cover 2 supply wires providing 120V & 240V. Drawing shows breakers immediately after main breaker -- the drawing is NOT on furnished instructions, and instructions says to just mount Device to an available knockout & have no restrictions on location.If you DIY install, be sure to shut off main breaker in the panel, but be aware that supply wires BEFORE the main breaker are ALWAYS live. Wires & contacts AFTER main breaker are off when main breaker is off. Thus, the panel is still hot when the main breaker is off so touching the supply wires can still kill you.I don't know why panel makers don't put a hard plastic cover over the supply (input) area that would cost 25 cents in material and save a few lives - a careless electrician or a novice DIY (I guess it's too much to de-risk and it's human fault if they are killed).

One of the best you can buy for the price! Installed easy and includes a lit indicator. Highly recommend for adding another layer of surge protection for the house

We live in a area known for its violent thunderstorms. This provides whole house surge protection against lightening destroying A/C and appliances.

I needed to replace a similar unit which no longer indicated it was protecting my house (no green LED). I upgraded to an 80ka unit from a 50 in order to improve the overall protection. The installation was pretty straightforward and I used a knockout on my breakerbox which allowed for easier wire routing.>>If you are not 100% comfortable working near exposed wiring, please call a qualified electrician<<Once the ground, neutral and Hot wires were connected, I flipped the breakers and the green LED came on.It turns out my local power company had been doing some hot switching and that may have caused the original failure. All of my electronics are working so I think the unit performed as specified. Very satisfied with the product.
