Read and understand the directions for SPD’s. SPD needs to be connected as close to Main as possible. If using a dedicated breaker you need to move either top breaker down the stack to make room. If one of the current breakers is the correct size and rated for dual connections (noted on side of breaker) you can connect black wires to existing breaker. Best way is to put ring connectors on black wires and mount to L1/L2 studs just below Main breaker as seen at 2:44 in your video. That is as close as you can get. No breaker needed, no breaker shuffling. Use a step drill to pop a 1/2” hole in the side panel even with L1/L2 studs for shortest run.

Had a dryer fire a few years ago that could have been a full house fire had it not been for the quick action of my nephew (I was away at work) and the ready placement of a proper fire extinguisher (our local volunteer fire department being five miles away made it for the cleanup, bless them all). Everything that was on at the moment got zapped (TVs, Oven, a couple of game systems), and the company that installed a new service from our pole said it was undoubtedly a surge, but from unknown sources. Our HomeOwners insurance (the people with the mighty Stag...) wouldn't pay a thing since we couldn't prove where the surge came from (of course, we changed insurance companies after that). Surge protection is well worth the costs!

Due to the physics of surge protection, it would be better to connect the ground as close to the grounding electrode conductor as possible (I'd put it in the next hole even if I had to move a wire out of it) and the wires should be trimmed to a minimal working length. But any install is better than nothing for surge protection!

Awesome video dude!! Thanks so much for the tips!!

I'm sure someone pointed it out earlier, but what you installed was the HEPD80 vs the HEPD50 as mentioned in the content above. Same installation techniques of course. Good work. - CED Antioch

Well done on the install. I looked up the specs on Square D surge protection and it's quite impressive.

[wazzouz]

Very helpful. Thank you. Much appreciated.

How would that surge protector be hooked up if you only have 110v so one leg on panel that’s my situation in Alaska at my remote cabin

[sparx]

Working in a panel box wearing a wristwatch. I could tell you horror stories about doing that!

[jayescreations]

I wanted to install this. however I dont have any blank spots for additional breaker.

[diydarkmatter]

thats a nice hornets nest you got there . lol . happy new year buddy .

[TheDaddygeek]

My circuirt panel is inside the house and embedded in a plasterboard wall. What is the best way to mount a whole house surge protector?

[BrittCHelmsSr]

How about that hornets nest under the breaker panel?!? Nice tutorial on how to install this surge protector.

[MercedesMechanic]

Is it your understanding that I must add a new breaker in an empty slot to my panel to use this? They say to hook it to a 15, 20 or 30 amp two pole breaker but they don't specify whether or not you're supposed to add a breaker just for it. Also, I'm wondering which size of these 3 breaker choices is the best or does it matter as long as its a 15, 20 or 30?

[Matt-ungi]

So basically the surge protector doesn't get installed in a series but is more of a passive device meaning it only has to be on a live circuit anywhere connected to the panel

[kennydcrypto]

You should never turn a 200amp breaker on with all of your breakers in the on position.

[VenomInMahEyes]

How does this surge protector work exactly?

[rickjames]

Um, not how I would mount it. Wires as SHORT AS POSSIBLE. As CLOSE to the neutral/ground buss as possible. Why? For every inch of wire length, you increase the clamping voltage by 20-25 VAC. So if that device dumps voltage/current at 600VAC, you add on say another couple hundred volts for example till it starts working. Shot wires short

Looks a little crooked might want to turn it to the right a few degrees.
