## Overview

The Square D HEPD80 is a robust whole-house surge protection device designed for 1-phase, 3-wire 120/240V residential systems. With an impressive 80kA surge capacity, it safeguards all connected electronics and appliances beyond the reach of typical power strip protectors. Featuring a compact form factor for easy load center installation and a handy LED status indicator, it ensures continuous protection and alerts you when replacement is needed.

## Description

Square D Brand Home Electronics Protective Devices (HEPDs) are compact and affordable surge suppressors designed for residential load centers. HEPDs work together with surge protection plug strips to provide surge suppression for sensitive electronics. HEPDs reduce surges that might otherwise overwhelm plug strips and damage connected household equipment. HEPDs also provide surge suppression for important items such as washers, dryers, refrigerators, stoves and air conditioning that plug strips may not or cannot protect.

Review: Hoping to avoid another costly replacement bill - After a power surge form a blown transformer that took out our refrigerator, dryer, two security cameras, two window fans, an electrical outlet and a motion detected outdoor light, I felt a need to protect my electrical appliances in the event of another power surge. With a $1000 deductible insurance plan, it still cost me over $1000 out of pocket to replace everything. I installed this on the main busbar in the circuit panel, ahead of the circuit breakers. It was very easy to install if you know a little about electricity. If it works, it will be well worth the $100 spent instead of $1000 if another power surge occurs.
Review: Best solution when breaker slots are all occupied - 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.)

## Questions & Answers

**Q: Will this protect from solar flares?**
A: Yes, this device will help protect (never 100%) the home from Voltage surges from any cause, including solar-induced surges.  Rare solar events CAN cause surges in commercial power systems.  No protective device can function in every case, however.  This is called science.

**Q: where do you install this? from the power meter to the main circuit breaker then to Square D then to the rest of the breaker tree?**
A: top reply by walker is incorrect...instruction offer two installation options 1) (preferred method) connect to service panel's bus bar "lugs" (just under the main breaker) these are always live if the main breaker is on, so you need to know what you are doing; option 2) connect to the closest (prefer first) double breaker slot (top two slots) on either side, and yes, use a 20 amp 240 V double breaker (so both 125V bars are protected).  Two separate 20 amp 120V single pole breakers (one above the other on the same side) "attach" to same bus bars as the double breaker, but if one breaker trips, you lose half the protection, so you want to use a 20amp 240v double pole breaker!   If you connect the HEPD to the top right single pole breaker and top left single pole breaker (one breaker on each side of the same "row"), you will only protect one of the 120V bus bars and not both.  That is why 240V breakers are double wide, so they connect to both 120V bus bars (the right side does not connect to one bus bar and the left side to the other).   Also, walker's mention of three wires from the pole...only two carry 120v each, the other one is the ground.  If you are not knowledgeable, hire a professional to be safe...if you install it wrong, the insurance policy it provides is null and void.

**Q: will this protect all the breakers in the panel or is it just for one breaker**
A: It must be connected to it's own breaker in the panel.  By doing that it protects the entire panel.

**Q: How do I determine how many of these I need for my house?  I have a main panel outside and 4 panels in the garage.**
A: What size is your main service entrance panel?One of these units usually covers a 200 amp residential service.Interesting (and a bit strange) that you have so many subpanels in your garage.What kind of equipment are you running in your garage that require 4 subpanels?

### ⭐⭐⭐⭐⭐ Reputable 80KA protection
*by M***D on November 29, 2025*

Easy install, using Wago 221-615 as connectors in my HVAC compressor disconnect box. Yes, 80KA is a bit of overkill for a compressor, but ... Obviously well made by a reputable company. Less stress knowing my fairly new 4 ton Trane XV18 is well protected.
