Your cart is empty. HEPD whole house devices are designed to deliver AC surge protection for the entire AC power system in a home. HEPDs are compact in size and are designed to protect AC wires in the home from surges that could affect home electronics and appliances not connected to surge strips. For use on 120/240 VAC single phase, 3 wire systems with an isolated ground. This device mounts easily next to the load centre. Load Centre color integration and flush mounting kits are available for separate purchase. This device provides 25 kA of short circuit protection and 80 kA of surge protection per phase and comes in a consumer package. The surge protection device is in a NEMA 4X housing. The surge protection device is 3.23 inches tall, 3.72 inches wide and 2.10 inches deep. The surge protection device is CSA certifed by UL.

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

Installation is pretty straight forward and took less than 15mins. You'll need a 2-pole 15amp breaker (a single pole would be okay too according to the instructions). Won't know if it works until (honestly do not want to find out). But it gives me an extra sense of protection for not a whole lot of money. We all have spent more money on other useless stuffs anyway.

Added this as the first layer of protection to all of my electrical devices in my house. Still have surge protectors near some devices.

Installed four for family over the holidays, this was the only one of the external units, since all but 2 breaker slots were occupied, and never throwing away the final 2 expansions!Installation was trivial, even bolted to the backplane bolts (see instructions for that detail). A 2 lug breaker/dummy isn't necessary, however, leave extra length for the 2 hot leads, and have someone experienced with working in panels made those 2 connections.Presuming you know how to connect ground and neutral safely in a circuit panel, you would later be able to power down the whole panel, cut the hot leads with enough excess length to wire nut the replacement unit's hot leads to the original wires when your initial suppressor has fried. You shouldn't need to clamp into the bus bars ever again.This needs to sit outside the panel, and the deepest 1/2" punch outs closest to the wall might not leave enough room for the box, we used a middle punch out. I used an extra threaded conduit nut on the inside and outside of the panel box so the surge suppressor case itself wasn't stressed. The green light is very reassuring that the panel is hot and surge suppression is active, but you might need a bit of electrical tape to cover if it is mounted in a bedroom or similar. If this can't be mounted directly to a panel because it is embedded in the wall, then order their recommended mounting kit, you won't regret it. (We were lucky and didn't need it.)

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 “betterâ€, 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 “fussyâ€. 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 30â€), 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.

Installed this Type 1 SPD in a Square D Main panel (will work with any panel with 1/2†knock outs) using the Direct method to L1/L2 posts below Main breaker as per device instructions. The Direct method Saves needing/using a dedicated breaker or wiring to existing breaker in panel. If mounting the SPD to the Main breaker lugs you will need to turn off the Main breaker when changing the SPD out if it fails after a surge. If using a separate breaker you only need to turn that single breaker off to change the SPD. I don’t gamble and always turn off the Main breaker when working on a panel so Direct wiring to L1/L2 is no issue for me. If you are electrically savvy, it’s a 15 minute job (using Direct method), 30 minutes if you aren’t. If you need to move breakers to get an open spot under the main you’re probably looking at an hour depending on how many you need to move. Understand that no Surge Protection Device protects from a direct lightning strike to your home. You should use SPD’s (Type 2) on each sub panel and quality outlet surge protectors at home electronics device outlets. Layered protection is best. Using a single SPD is a gamble.

Installs super easy, but won’t know if it works till I get a strike, which is hopefully never. Cheap insurance though.

Installed on in a new electric panel and so far it seems to be working as it should.

Although I doubt that my electrical box has had a direct overload hit since I bought this whole house electrical breaker many years ago, I believe it's well made, and I have high expectations of this product manufactured by a well-respected company.
