Hi, I appreciate the video and is a protection indeed, better than having nothing. And, as it is it will protect. Yet, is important to read the instructions and the two hot wires need to be braided or twisted in order to be more efficient, especially when it travels so far in the panel. Surge arrestors behave different and just like a low voltage wire, these can get noise in the current so two wires traveling on parallel such a long distance will surely affect response. Also, avoid loops and bends. We old timers knew that it cannot be sharper than the bottom of a soda can when it comes to turns. Keep it short. Speculating that you need to move it is worthless, the purpose is to optimize the protection and if anything, any breaker you need to move then move another and these breakers should get closer to the point of entry. You want any voltage tsunami to hit the protector way before it bleeds into appliances close by. There are other details, even some cosmetic ones, like my father would have made a fit if I left all the debree and dirt inside the panel. Is good to clean them so inspectors/customers know you are meticulous and go the extra mile, it helps set the mood in the inspection. Nonetheless, as a minimum, twist the wires like the instructions for this particular surge protectors asks. That is utmost important. All that said, thank you for posting a video, at least is technically correct and it does protect the way you did it, but improve it with the aofrementioned, each nanosecond you can get is paramount.

Supposed to install as close to the main as possible & supposed to cut all excess wire. I did chuckle the minute you said leave at long as possible lol.

wires should be cut as short as possible. every extra foot of wire gives 500-700v of let through during a spike

Can you just sit the protector in the panel is the panel is a recessed panel and has drywall all the way around

Best location is where the RAW power comes INTO the panel. Prior to the main breaker. Always use NO-OX or similar anti corrosion paste on the wires. Never put two wires/cables into ONE lug. That is a fire hazard. All wires MUST BE short as possible. End of message on that. For every extra foot of wire, you add more to the clamping voltage where this was designed to work. Short wires short wires...... Do NOT install your SPD at the opposite end of the panel LIKE IN THIS VIDEO.

Wires need to be as short as possible Also breaker need to be close to main feed not on top. Last but not least install a ground bar

Thanks for the video! Was very helpful

The breaker needs to be the closest to the main breaker to protect downstream or be attached to the lugs of the bus bar

Thank you for the video. Somewhere in the installation instructions, I read for "optimal" protection, the wires from the HEPD to the breaker should be as short as possible. I like the ideas of keeping the whole length of the wires, but is it ok to keep it long, or should we cut the wires to be the shortest possible between HEPD and the breakers. Thanks

Surge protector should be as close to main breaker as possible

What happened if I run out of space to put breakers? Can this be put in a breaker that is already used?

Thanks for making this! You got any tips for mounting in a recessed panel with drywall up? Also, some models allow mounting directly to the bus without needing a 2 pole breaker, which is pretty cool

I noticed you decided to install your surge protection device downstream of all existing breakers. Can you explain how your setup will protect the existing breakers from an initial surge from, say, a lightning strike? I would assume each existing breaker has roughly 40 to 100 feet of 12/2, 12/3, 14/2, etc. of supply/return wiring. That's a lot of initial surge that will run from your 200amp breaker to your sequentially installed sub breakers per the bus bar before it hits your surge protector. I would think that theoretically, your system could endure over 1000 feet of wire surge before you displace the remaining surge. To further explain my question...the 200amp breaker can be set to the off position to kill all breakers connected to the bus bar, right? That means power flows from the 200amp breaker to the bar. The surge protector is located at the last point of initial flow, so the same would go for an initial surge.

Does this need to have its own breaker installed or can you stack this on top of an existing breaker?

Thanks for your help!!! I have a question, what device should I buy if I want to protect my house from HIGH and LOW voltage?

I have a 240 V Single phase panel (Off grid inverter) Can i just combine the 2 black wires and place that right on a breaker. Or is this designed only for Split Phase 110/110 ? Thank you!

Since you are using Square D breakers with a two wire connection at each terminal of the double breaker, why not install the two hot wires into an existing 15 amp double and save the expense and trouble installing a new breaker? This is useful if you don’t have the space in an existing panel for an additional double breaker.

Why did you pick 15a breaker?

What if you have multiple panels in your home? If you don’t have space in the main panel, do add the surge protector to all sub panels?

Will whole house surge suppressors help prevent failure of GFCI/AFCI breakers? I have to go replace two breakers at a rental today because a storm took them out. And those breakers are expensive! Have had to replace them in other rentals too.

Do I use an existing breaker that’s already in my panel or am I supposed to buy a new one that’s fully dedicated to this Hepd50?

Can you install this on a sub panel?

Can i plug this into a subpanel if my main panel doesn't have any more bus space?

Thnks for the video. If I don’t have any space for a 2P breaker, can I connect it directly in the main lugs ?

hi can plug this on MCB breaker? thank you

Not sure why you do not go direct to the buss for every one of these you install. Am I missing something?

will this HepD50 protect Solar Inverters?

What about 3 phase? Do I connect to the two low legs?

nice video, so let me understand - the surge protectorwill cover all the circuit and or breaker in the panel ? or just an specific circuit ?

How is it installed to 120v?

Ground and neutral on same bar??

Will this protect a sub panel that's wired to the main, or should it be installed separately at the sub? Thanks.

is this a mandatory in year 2023? the electrician it is.his charging me $600 for it

Do you need a permit to install this? I think I know the answer.

you are wrong the protector goes first where the current from the meter enters

Looks like a lot violation on the panel 🤷🏻‍♂️ judge you self grounded and neutral together. Panel is upside down

Just because you own a screwdriver doesn't mean you should be installing an SPD 1 device in your panel. As in installing the SPD at the opposite end of the panel where it doesn't belong. Stay out of that panel if you don't know what you are doing.

Hello, This is straight from the manual: "To enhance the performance of the HEPD50/HEPD80, twist and keep the conductor length as short as possible by trimming down the wires (do not loop or coil the wires and avoid sharp bends). Always secure the L1 and L2 wires with keps nuts and ensure proper connection. Increasing the HEPD conductor length will degrade its performance." Might be an idea to trim it down some if possible.

Totally not how the instruction say to install it. It says to connect to the bolts below the main lugs. That way the entire panel is protected
