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

I had been wanting to install one of these for quite some time and finally did it. Not only is Florida experiencing more and more lightning strikes, but we're almost guaranteed to lose power and have to run a generator after a hurricane. This one gets good reviews. Was easy to install above the service panel.

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!

This unit will work with pretty much any mfg. breaker box.Square D reputation and reliability is stellar.80KVA is probably the minimum size to use for whole house surge protection. It won’t protect “better”, but because they are sacrificial units they will last longer before needing to be replaced.This unit is designed for AC power line protection only.Units that protect cable & phone will require (re)running those lines to your breaker box. I didn’t want to do that.Unless you are installing outdoors, the NEMA rating really doesn’t matter.Install is generally straightforward, but is a little “fussy”. Read the directions!Remember to shut off your main breaker 1st and note that the input lugs are still always hot.The Hot lines should be connected as close as possible to your 1st two circuit breaker circuits.The unit should be installed as close as possible to the chosen breaker.Keep your lines as short as possible- no loops or kinks. If possible, twist your leads.The leads are long 30”), heavy gauge, and pretty stiff. Maybe from the way they are compactly wound for packaging.The only glitch I had was that the unit didn’t want to work when I 1st powered things up.The second power cycle was the charm and it’s been up ever since.

This deviced has proven itself to work well. Make sure you connect it to the first leg and dont cut the extra wire but loop it into spirrals on a pencil. The loops help with distant lightning strikes that could damage TVs

I bought this to install in my remote sub panel that powers all my pool equipment. We have an in ground pool and wanted surge protection for the variable speed pump, salt water chlorinator and automatic pool cover. It is pretty simple to install if you are comfortable with doing some minor electrical work. IF NOT COMFORTABLE WORKING WITH 220v do not DIY and get an electrician. Since in my case I was installing in a sub panel, I shut off the power to the panel (which was controlled by a breaker in the main panel). I then removed the cover for the sub panel. I punched out a panel hole, unscrewed the supplied mounting ring and fed the cables into the panel and mounted the box on the outside of the sub panel. I cut the neutral (white) and ground (green) wires and screwed into the neutral and ground planes in the sub panel. Then I installed a new dual pole 20 amp circuit breaker. You should check the maker of your panel/sub panel and purchase one which is compatible with it. I then cut and screwed in the two power lines (black) to the two screws on the breaker. Remounted the cover on the panel and turned on the power to the sub panel. I then turned on the new circuit breaker and noted that the 2 green LEDs came on as expected. So now these pool devices have some protection.Even if you use this on your main panel, I would still suggest an appropriate UPS (uninterruptible power supply) for high cost devices like computers, receiver, big screen sets, .., as the UPS will provide protection from more than just a surge.Definitely recommend this to provide a means to provide a level of protection at the panel level. Of course I won't know if it is great until, if ever, it gets fried from a surge and saves the other equipment.

I live in Florida and we go through some of the most ugly thunder storms in the USA. I installed this surge protector as per instructions and I have never lost any of my electronics. I am very pleased with how it operates and protects my home.
