Square D HEPD80 Surge Protector Review

Square D HEPD80 Surge ProtectorThe Square D HEPD80 (from Schneider Electric) is one of the more popular surge protectors in the market toady. It’s easy to fall in love with it but it’s also important to know everything that you’ll get when purchasing this device.

In this review, we’re going to learn the most important and essential facts about the Square D HEPD80. You’ll get to know why it’s really popular and you’ll also learn some of the cons that you will encounter with it.


The Square D HEPD80 has a very high surge current rating of 80,000 amps. If you want to have an idea on how high this surge is then think of it as a direct lightning strike. The Square D is going to protect you as much as any other expensive surge protectors in the market.

If you take a look at plug-in type surge suppressors you will notice that they only provide you with 30,000 amps of protection. It’s a good first line of protection but for some people, they would still need a second line of protection by using surge protection power strips.

Installation of Square D HEPD80

Generally this surge suppressor is very easy to install provided that you have some background and experience with electrical stuff. It’s recommended that you have to install this on a 2-pole 20 amp breaker. If you don’t have any spare then you have to get one. After that, you just hook in the 2 black wires to each half of your 240V breaker. Then the green wire goes to the ground and the white wire goes to the neutral bar.

If you see the 2 green lights illuminated when you switch your main breaker on, then it means it’s already running and you’re already protected.

If you have no idea on what you’re doing, I would recommend that you hire a local electrician just to make sure that everything will be fine.

Square D InstallationIf you decide to install it yourself, give yourself a good amount of time in order to avoid rushing the installation. If you have some wiring experience, it will probably take you around 20-30 minutes.

The Square D HEPD80 is designed to be mounted directly to your breaker panel through an open punch out. But you’ll have a bit of a challenge if your panel is flushed mounted to a wall. If this is your situation, then it’s probably best to attach the protector inside the panel. Some even drilled a hole into their wall in order to open a punch out and slip the wires inside.

Take time to consider your mounting options in order to make sure that it’s not going to be in the way of a door or any moving structure.

Take note that you might have some trouble installing this in a larger panel with not a lot of room in the side access. The reason for this is because in bigger panels, you only have a limited number of open punch outs. It even gets worse because the neutral and ground bars are not really long enough to reach all the way from the end of the box using the built-in wires.

The length of the leads is 20-21 inches and hopefully the length is enough for you in configuring this device in your breaker. In some cases, you might move some of your breakers but in general situations, the length of the leads were enough.

It’s very important that you do not extend the wires as the protective ability of a surge suppressor weakens with wire length. So keep in mind to keep the wires as short as possible.

When you talk about the build, the Square D surge protector is made up of durable materials and is outdoor rated making it safe to endure the outside conditions.

LED Lights

The HEPD80 will have 2 green LED lights and each light actually monitors the two phases of the 220V breaker separately. One of the lights doesn’t have any label. The other light has a label that will tell you whether it’s OKAY (illuminated state) or if you need to REPLACE (lights out). If one or both of the LED lights are out, then you need to take action and replace it for continued surge protection.


Like you’ve read earlier, the Square D HEPD80 has a surge rating of 80,000 amps. If you do a quick search for surge protectors that also has a rating of 80K amps you might be surprised to find out that their prices can reach up to over $400.

There are even surge protectors from big name brands that costs over $1,000 but the truth is that they don’t compare to the high level of protection that Square D is providing.

You can do some investigating for yourself if you want to. Look at the voltage protection (VPR) ratings and the lower the number, the better it is.

Basically, the VPR refers to the voltage that will trigger the surge protector to protect every electronics inside your house. If you ask your local electrician about this, they will probably tell you the same thing… that most of the time cheaper units are actually more effective than buying expensive branded products.

Here are some of the VPR specifications of the square d:

  • 600 V from Line to Neutral
  • 700 V from Line to Ground
  • 1,000 V from Line to Line
  • 1,000 V from Neutral to Ground

How Much Is Your House Insurance?

Here’s another perspective that you can think about when it comes to saving money. If you have some house insurance, the price of the Square D is fairly cheap. It’s definitely well worth your investment when it protects your electronics if ever you get a surge.

As you can see, this surge protector provides you with the highest level of surge protection while having a very reasonable price point.

What Are The Issues of Square D HEPD80?

Length of Wires

Like you’ve read earlier, you might have some concerns about the length of the wires. Again the length of the wires is 20-21 inches. Some people have some issues with this but in the end they got the Square D installed. Generally, a lot of people are satisfied with the length of the lead wires and were able to install it fairly easily.

Claiming Headaches

This one is not a direct issue with the Square D HEPD80 itself but when it comes to filing for a claim, I found out that you have to go through a lot of hoops in order to get it. There are many steps that you have to fulfill like verifying the damage cause, filing insurance claim within a month, independent evaluation, etc. If you don’t complete any of the steps then your claim is going to be null and void.
