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.
Right ! Make those wires as short as possible 🎉
Agreed. If the SPD will absorb *50 KILOAMPS* then the surge voltage will be whatever rated voltage the unit clamps at *PLUS* the voltage drop of *50 KILOAMPS* flowing through the resistance of the connecting wiring. I'm not sure what gauge wiring the SPD comes with. If it can be installed with a 30 amp breaker, then I'm guessing that it's #10 AWG. I looked it up and it has 1.02 Ohms per 1,000 ft. So, 5 foot leads would add the resistance of 10 feet of wire, or .00102 ohms. 50 kA of surge current would boost the clamping voltage by 51 volts. You'd need to analyze whether that's acceptable. Cutting the leads would reduce that.
*_YMMV!_* My electrical engineering degree is 48 years old, but unless the sneaky government *_changed Ohm's Law_* ... 😀
One additional point - you do not required additional breaker, direct bus install is an option. The only reason for the breaker is the ability to shut off the device without shutting power to the whole house.
They will work anywhere on the panel. Preferable to be closer but does the same thing.
wires should be cut as short as possible. every extra foot of wire gives 500-700v of let through during a spike
I have never heard of this. Can you explain more pleasee?
the sure protector should be right after the main breaker withe the wires from the surge protector twisted once an inch and directly to a breaker . i used a 50 amp dual pole as instructed. this method of short wires makes a more effective protection. follow the directions. it’s possible that square d didn’t mention this. i installed an eaton ultra surge protector and had specifically stated to do as i’ve stated on the install.
@@harrydoherty8299 thanks for the insight. Just to clarify, can you expand on "twisted once an inch"?
@@harrydoherty8299 ok so i just read the installation instructions and yes I see that they state "have one twist per inch to reduce the impedance of the wire." Still, I don't get it, so the shape they want is like the old telephone wires that are like a pigtail?
Thanks for the video! Was very helpful
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.
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
Hi. Thank you for watching the video. I think it's fine for the wires to be a little longer (slack) than you need in case you have to move / add breakers to your panel in the future. If you cut them the exact length you may limit yourself in the future. Hope this helps 👍
the shorter the better but if you need to keep them quite long then braid or twist them per the instructions, this will optimize since it kills the noise and lets the protector absorb much more, much faster to shunt.
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
Hi Austin. The bus bar mounting option is a choice with this one as well. I just don't like doing something like that where the bus bar lugs are loosened and then retightened. If they are not torqued down properly it will affect the entire panel. I like the breaker option because it's quick and effective 👍
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?
The breaker needs to be the closest to the main breaker to protect downstream or be attached to the lugs of the bus bar
Hi Troy. Thank you for watching. However, I will have to respectfully disagree. The instructions clearly state that this surge protector will work effectively regardless of which breaker location it is placed at. The bus bar installation is an option as well. I did not opt for that as I do not like loosening up factory torqued lugs. Hope this information helps 👍. The installation instructions are very clear on what is acceptable for this surge protector to work and remain within warranty.
@@YouCanDoIt2 that’s a alternative method to wire it but it’s also noted on the instructions when installing the HEPD and increased its effectiveness wires should be twisted together and trim down shortest as possible also is ideal to be placed to the incoming power source
@@YouCanDoIt2 From the instructions you linked:
Note: 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 connect the HEPD
to the circuit breaker(s) found in the
closest proximity. Increasing the HEPD
conductor length will degrade its
performance
There are SPDs that only have two hots an a neutral cables. But this HEPD50..has 4 cables...including ground....Maybe, this might be the reason that you can install it far from the main lugs...
@@learningpower9437 The instructions I posted from the company say otherwise.
Always connect the HEPD
to the circuit breaker(s) found in the
closest proximity. Increasing the HEPD
conductor length will degrade its
performance
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?
Hi! Thank you for watching the video. There are surge protectors for motorhomes that protect for both low and high voltage swings. There is a company called Ditek that has surge protectors for low voltage. As far as providing whole house low and high voltage surge protection I am not aware of any. Not to say that there aren't any out there, I just have never really searched for that.
@@YouCanDoIt2 Thanks 👍
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
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 Alberto. That you for watching the video. Installing on the main lugs is an option. You need to follow the installation instructions on how to do that. Those main lugs really need to be torqued down nice and tight to avoid issues downline. Best wishes with your project 👍
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.
Hi Kevin. That's a good question, but not very easy as a black and white answer. The purpose of a whole house surge protector is to help minimizes the effects of power surges that may come into your panel, due to storms, outages, etc, that can cause appliances to fail. I would hope that this device would also help to protect the breakers in the panel, but that is something that you might need to call the manufacturer about. I hope that this information helps or points you in the right direction 👍
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.
Hi. This install is to manufacturers specifications. The specs, according to sheet NVE82551, call out for two best practice options. The first, is the one I chose to do. The second, is installing the surge protector to the bus bar / lugs. The problem with this installation, in my opinion, is the loosening of the lugs and retightening. If you don't get those lugs torqued down properly, then you wind up with loose connections down the bus bar feeding multiple breakers.👍
@@YouCanDoIt2 👍
surges take the path of lowest resistance so you. can mount anywhere on the panel
@Joe D True, but if you mount it at the bottom of the bar, you have 100 times more of a chance for the initial surge to hit anything mounted between the main breaker and the surge protector. Don't believe me, just email Schneider and ask.
@@DaysAhead202 Schneider purchased the surge co. that i was a product manager for the SPDs. i am responsible for bringing several of these products to market. i am very knowledgeable of how MOVs work, wire lengths, OHMs law , path of least resistance,grounding, clamping voltage, let thru voltage, class A,B, C products, UL1449., shunt to ground, line fuses, SCCR…
will this HepD50 protect Solar Inverters?
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?
Hi Mercedes Mechanic, great question! Technically no...but, the installation instructions do state that it you hook this up to a breaker that is feeding something in the home, and that breaker trips, then your entire panel is unprotected until that breaker is functioning again. I have added a link to the instructions on my description...but have included it here for you as well.

Hope this information helps you 👍
Surge protector should be as close to main breaker as possible
Does this need to have its own breaker installed or can you stack this on top of an existing breaker?
Hi John, great question! Technically no...but, the installation instructions do state that it you hook this up to a breaker that is feeding something in the home, and that breaker trips, then your entire panel is unprotected until that breaker is functioning again.

Hope this information helps you 👍
Not sure why you do not go direct to the buss for every one of these you install. Am I missing something?
Can i plug this into a subpanel if my main panel doesn't have any more bus space?
Hi. That is a good question. The answer is yes and no. If the subpanel is located next to the main panel, then the surge protector will operate properly. However, if the subpanel is located somewhere else, causing a delayed reaction to any energy surges, then it will not work to protect the main panel properly. So, the real question is distance between main and subpanel. If the panels are less than 10 feet apart from each other, you should be fine. Hope this helps 👍
@@YouCanDoIt2 Thanks! unfortunately my subpanel is located much further than 10ft, so I guess Ill just end up buying some surge protected power strips instead. Would have been nice to install, but not much I can do I guess~
Will this protect a sub panel that's wired to the main, or should it be installed separately at the sub? Thanks.
Hi Rich. Thank you for watching and leaving a question. Surge protectors should always be wired into the panel that receives the power from the source (utility company). This would be your main panel. Everything downline such as your sub panel would also be protected. Hope this information helps 👍
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.
Hi Robert. I see what you are saying. However, some states / counties don't allow double-tapping at the terminal of the breaker. I did the cleanest install according to the manufacturer specifications sheet NVE82551. There is a note on the install sheet that states that you can install this on a breaker that is indicated for multiple conductor use. However, if that breaker is tripped due to overload, the surge protector will no longer serve as a protection to the remaining breakers in the panel. Therefore, the purpose of installing this protector becomes void. If this is isolated on its own breaker it serves as continuous protection for the entire panel regardless of tripped breakers downline. Also, some products will not warranty their item if it is not installed according to their specs. Hope this information is helpful.👍
hi can plug this on MCB breaker? thank you
Hi Melgar. Thank you for watching the video. An MCB (miniature circuit breaker) is meant to prevent surges in electricity, usually used for low voltage applications. In a way, it is a surge protector already for low voltage use. I would not attach this whole house surge protector to one of these breakers. I would find another breaker with a standard breaker to use as the landing source. Hope this information helps👍
What about 3 phase? Do I connect to the two low legs?
Hi. Thank you for watching the video. This surge protector is good for a Homeline addition, residential surge protection. You will need to go to the Square D website for a commercial grade surge protector that is good for 3 phase installation. Hope this information helps 👍
Can you install this on a sub panel?
Hi Jason. Thank you for watching and leaving a question. Surge protectors should always be wired into the panel that receives the power from the source (utility company). This would be your main panel. Everything downline such as your sub panel would also be protected. Hope this information helps 👍
Ground and neutral on same bar??
Yes. The neutrals and ground go on the same bus bar for a main panel. The only time you need to separate the ground from the neutral is on a sub panel. Hope that helps 👍
Do you need a permit to install this? I think I know the answer.
Hi Miss Jenni! That is a good question. For the answer you would need to look into your own city / county codes. Some require permits for installing a doorbell😀. This is technically the addition of a breaker into the panel that protects all other breakers. Hope this information helps!
@@YouCanDoIt2 thank you. Yes it does. For most electrical like this, we usually hire out for the work. That way we know personally it was done right. 😄
@@MissJenni_ISO Yeah, but.... Unfortunately, there are a lot of installers that don't know how to follow instructions or best practices. I tend to do things myself and I know to blame the guy in the mirror if anything goes wrong. Best of luck to you on your project.
How is it installed to 120v?
Your home and just about every home in the USA has two 120v circuits coming into your home and the breaker shown in this video uses both so you can get 240v to those appliances that run on 240v such as a stove, water heater or AC unit, This is why the surge suppressor has two black wires, to protest both of the 120v circuits. I hope that this addresses you question.
is this a mandatory in year 2023? the electrician it is.his charging me $600 for it
Hi. It really depends where you are located and what NEC codes have been adopted in your county. If your area has adopted the 2020 NEC requirements then the answer is ""Yes". All single and multi-family dwellings are required to have surge protectors on the panels. I hope this information helps you. 👍
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.
Looks like a lot violation on the panel 🤷🏻♂️ judge you self
grounded and neutral together. Panel is upside down
you are wrong the protector goes first where the current from the meter enters

Nothing says it has to b first breaker...check directions
@@brianmeeker3058 Hi Brian. I'm not sure if you're referring to my comments or Juanquisal's. I did not say that in my comments that I put this in at the first breaker location. I did the first option that that was called out on the manufacturers installation instructions. Hopefully that clarifies for you. If you watch the video it clearly was not installed at first breaker location 👍
@You Can Do It sorry that was for the comment before mine.. just put 2 in today
@@brianmeeker3058 No problem 😂. That's why I was trying to be vague with my response as I figured you very well could be referring to the original commenter. You'd be surprised how many people leave horrible comments on things they don't know much about but make you feel like you're the absolute idiot.😅
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

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.
