EMP & Lightning Protection For Whole Home | EMP Shield

Home EMP Shield protection from lightning and EMP pulse.

Whole Home Lightning & EMP Protection

I am excited about technology that’s targeted towards Lightning and EMP (electromagnetic pulse) protection. Why?


Because we get plenty of summer thunderstorms here (as I’m sure many of you do too). A product purposed to help protect valuable equipment in my home from a lightning strike is worth looking into!

There’s always a chance that lightning will blow up your stuff. It happened to me last summer! And there may be circumstances where lightning causes damage even with protection devices in place. However I am inspired to tell you about protection products from ‘EMP Shield’ – which look very good! I’ll get into that in a minute…


Another reason I’m excited about their technology is the protection from a more sinister modern day threat. EMP (electromagnetic pulse). I’ve written about this threat quite a bit. Rather than explaining it here, I’ll insert a link to the category in case you’re interested to browse the topic:

EMP Category on Modern Survival Blog

The EMP Shield is listed by the Department of Homeland Security in their recent EMP Resilience report. The EMP Shield is evidently the world’s first military tested EMP protection technology for an entire home (and vehicle).

Built to exceed military standards (MIL-STD-188-125-1, MIL-STD-464C, and MIL-STD-461G).

EMP Shield is one of the World’s fastest whole home surge protectors operating in less than 1 billionth of a second (1 nanosecond).

Our devices have been military tested and proven to defend against the E1, E2, and E3 phases of an EMP.

Here’s a related article: Nuclear EMP Components E1, E2, E3

Briefly Explain E1 & E2 EMP (pulse components)

Here’s what EMP Shield had to say about it during a recent correspondence:

The E1 portion of an EMP is caused by the gamma radiation (Gamma rays / photon energy) from a nuclear blast hitting the atmosphere.

This radiation/rays hitting the atmosphere causes ionization which shoots off electrons towards the earth.

There is a huge misunderstanding about EMPs. During the E1 and E2 phases, the earth is being showered with freed electrons. I get questions on a daily basis. People believe the only solution is a Faraday cage. They know EMPs are dangerous but simply don’t understand what they are.

The E1 and E2 is simply freed electrons being showered towards the earth.

How EMP Will Destroy Electronics Without Protection

I had asked their opinion how an EMP will damage ‘electronic devices’ and how their EMP protection device works. He went on to say this:

Now, that’s not to say the first two phases of an EMP aren’t dangerous because they are.

To directly address the question, everything that’s a conductor will induce these freed electrons from the E1 and E2.

This includes items in your home like the romex wiring in the walls and everything in the home that is a conductor. Many things within your home can and will get destroyed.

That is a huge reason why people need the EMP Shield in their home. The EMP Shield shunt (short to ground) all induced electricity within the home above our devices clamping level (level of voltage that would be detrimental).

The Shield shunts incredibly quickly at 500 trillionths of a second. It will protect the homes electrical system and all devices plugged into the electrical system.  

The EMP Shield not only protects against the induction of electricity within the home but also stops the huge surge of electricity trying to come in to the house from the grid through the power lines. 

EMP Protection For Solar Power Systems

I asked about protecting solar systems. I have an off-grid solar power system which essentially resides side-by-side with my grid power (separate circuits). There are currently protection devices in place. However I am highly curious of EMP Shield, given their ability to clamp down extremely fast. Fast enough for the E1 pulse of an EMP. I’ll mention CME in a minute…

For solar systems we have DC EMP Shield built specifically for certain voltages of the systems inverter and/or charge controller depending on if the system is grid tied or off-grid.

What many people don’t realize is that a solar panel has thousands of feet of copper trace in them. This means the panel (or multiple panels) serve as micro grids that will collect large amounts of electricity during an EMP.

Inverters, charge controllers, and other items within the solar system will be destroyed if the system doesn’t have a EMP Shield attached to it.

E3 EMP (pulse component) and CME Protection

What about the E3 effects, or the effects from a CME (coronal mass ejection) from the sun. These effects can go on for hours, even days. It’s a different but similar situation to deal with .

The E3 portion of an EMP is caused by the fluctuation of the magnetosphere caused by the large blast.

The blast pushes out on the magnetosphere and causes it to vibrate. It continues to fluctuate and vibrate until it settles back to its normal position.

This fluctuation will cause electrons to spiral down toward the earth and may last for many hours depending on the size of the blast.

As the E3 phase can last hours, this is most harmful to the grid as it will continue to build a charge over time. Its important to highlight that the E3 phase of an EMP is similar to a coronal mass ejection (CME / aka solar flare). 

How Do You Know If The Protection Device Burned Out?

I asked if there is a way to know if the EMP Shield protection device has burned out. For example lets say there was a lightning strike at your location. How would you know if the EMP Shield device had burned out?

Answer: We have included LED lights on all devices to indicate that the device is actively protecting the system its connected to.

The only thing we have found that will cause the shield to stop functioning is a direct or very close lighting strike. In the instance of a lighting strike the shield will offer 100% protection to the home electrical system. However, the shield will die in the process.

We have a limited lifetime warranty with each device that is good for 10 years and the device will be replaced for only $50.

As for EMP strikes, we have tested the device up to 42x times in the military testing lab and saw NO degradation to the device.

The device is also designed to trip the breaker during the E3 portion of an EMP. In this scenario the indicator lights will go out because the breakers have been switch off. This is by design to prevent extreme levels of electricity from entering the house from the grid. 

Wire Gauge Size?

I also asked about the apparent hookup wire gauge size of their device. How it handles the potential current flow during shunt.

About wires: It’s all about speed.

The wire size is perfect for our device as we have proven in our testing. We have also just recently passed UL1449. With the ability to shunt at 500 trillionths of a second, we don’t need thicker wires. 


He went on to mention that they offer a 100% guarantee against lightning. They specifically knew of six houses with their EMP Shield device which got hit in the last 12 months. ZERO damage to the homes electrical system or appliances.

HEMP Surge Protection Products

EMP Shield LLC has a family of EMP Defense technologies designed and tested to exceed the military requirements of MIL-STD-188-125-1, MIL-STD-461G, and MIL-STD-464C.

Various models protect the primary/backup power supply, communication lines, low voltage controls, antennas.

All production units begin shunting over-threshold voltage in less than 1 nanosecond, from conductor to conductor, conductor to ground, conductor to neutral, and neutral to ground, with a capacity above 100kAmps.

EMP Shield is an advertiser with us (full disclosure). I’m glad they came on board given my interest in this technology and the protection it provides.

  1. I have several faraday cages, home-made, here at the house. Different sizes and different levels of ease of entry. I am quite concerned with this issue, EMP, CME, even directed emp weapons.

    The small wires:
    I’m certainly no expert, but I’d assume a huge flow of energy, all at once. Yea, I realize volts alone won’t do tremendous damage, but these look to be 12 gauge maybe 10 gauge at the most??? Just going by the photo. The whole thing may be larger than I realize.

    What is the actual mechanism involved with the diversion to ground? A mechanical switch? Some type of fuse or breaker? If it is a circuit board, what makes this board different from every other circuit board we’ve all been lead to belief will “melt?” The speeds they are claiming are too fast for fuse/breaker, right?

    I don’t mean to be hyper-critical of something I know nothing about. I am a very likely customer.

    Just reminds me of a story told to me by my grandfather. A company advertised a bug killing product. Promised to give twice your money back if it didn’t work. When the product arrived, it was two blocks of wood. They were labeled Block A and Block B. The instructions read, place the bug on block A and strike sharply with block B. According to my grandfather, the company was even sued, but no one could beat them in court.

    I don’t know if faraday cages will work or not. I certainly hope they do, but no one will know until after the fact. Same thing here, with this product. I want to believe, I really do. The price is not outrageous and if they actually work, a bargain.

    I looked at their website a few days ago. I think I need to do more reading/research. I don’t really know how a company can prove their product, other than what they claim to have already done. For now, color me a likely customer.

    1. Plainsmedic,
      If you are ever serious about purchasing a device such as this one, do your due-diligence and contact them with your questions.

      I know they don’t use MOV’s because I asked them about it with cross reference to what I currently have in my home (and solar system) for protection (which uses MOV’s).

      Regarding Faraday cages, yes of course they will work if designed adequately. This article does not suggest that they don’t work (I hope I didn’t suggest that!). It is very wise for anyone concerned about EMP, to have backups in a Faraday cage (whatever ‘backups’ mean to you).

      Regarding the gauge, my current protection devices (another company) has similar looking gauge size. My estimation is it’s more about high voltage and low current. I know that apparently an EMP may induce a 50KV per square meter charge. The potential current dissipation in this regard (EMP) is unknown to me.

      This company has evidently been tested via the military specs listed in the article. Again, if you’re considering this device, please contact them with your specific questions.

      1. Ken,
        No, you did NOT suggest faraday cages don’t work. I only noted the faraday cages I use, to show my sincere interest in protection from emp/cme. Yea, I’ll contact them and see what they have to say. An interesting product. Glad for you, ya got ’em for an advertiser.

        The fact remains, we’ll not know for sure what works and what doesn’t, until after the event. Warranties will be a ridiculous concept post emp/cme. We’ll have way too much other stuff to worry about.

        I’ve got an old jeep cj5 for my emp vehicle. Replacement parts are in faraday. It would be great to have a pick-up as well. I doubt I’ll be going far anyway, but who knows.

  2. For what it’s worth, whole house surge protectors have been offered by our electric co-op for years for about the same price this company is offering. Important to note, the one offered by the co-op is not represented as emp protection. Never seen one, much less purchased for my home, nor know anyone that has so I could inspect it.

    I’ve lost mucho electronics over the years to power surges, both to devices “protected” with individual surge protectors that failed, and unprotected devices. I’m guessing I’ve had devices survive surges due to their surge protectors, wouldn’t know for sure.

    I lost one computer, an older desk top with monitor and tower, and a satellite TV modem and transponder, due to emp from a lightning strike in my yard. It entered the electronics through a hardwired router, seeking ground. It resulted in smoked and fused ground lug in the wall outlet.

    I notice that the company we are discussing diverts to ground, something my surge protectors don’t. They only disrupt the surge on the hot wires.

    1. Dennis,
      Here’s a quote, “All production units begin shunting over-threshold voltage in less than 1nS, from conductor to conductor, conductor to ground, conductor to neutral, and neutral to ground, with a capacity above 100kAmps.”

  3. This is really interesting to me, living on Lightning Point and all.
    Looks to be basically shoving everything to ground when it senses a power surge.
    Would play hell on the main breakers and all others but who cares if it actually works.
    I can see why it works on incoming and surge created inside the home both, a very simple direct to ground outlet for the current from L or an EMP.
    Good find Ken

    1. PS:
      An interesting little tidbit I learned from my Insurance Crooks.
      If a power pole gets hit by Lightning and does damage to your home, they will investigate to see where the strike hit.
      My power comes from a pole thats on my neighbor’s property, comes underground to my home, via a easement.So if the strike hits the pole my company will not pay off, I have to have the neighbors insurance pay for the damages….
      Nice huh?

      1. Yes and the neighbors insurance company will not pay off. I had this exact event happen to my home and my insurance had to cover it. Then my insurer dropped my home coverage.

    For you desert dwellers

    Efficient grounding electrical equipment, I believe is dependent on some moisture in the ground to actually conduct the current. All rock could be a problem. So deep rods may be needed.

    I’m no engineer but grounding may be pertinent to this EMP gadget.

    1. hermit us:
      You are exactly correct. Hence the new electrical codes here require 3 10′ rods 12′ apart and a 1/2″ 20′ rebar in the concrete foundation. All connected with a #2 copper ground loop.

  5. Question, would lighting rods be of any good? the style that use to be seen on every farm house yrs ago?

    1. alfie:
      I actually have a lightening system installed. Now days we use whats called a dissipator, looks like an upside down broom, that dissipates the static charge that draws a Lightning Strike.
      This Articles device is for a srtike or EMP that would follow the electrical wires into the home, not a ditect lightening strike.
      A direct Home Strike is a very nasty animal to deal with. Think of a regular strike as 24million volts and enough ‘power’ to run NYC for 3 days.

  6. We’ve had 2 lightning strikes on the home, one through the breaker box, the other through a router. There was some obvious immediate damage, but then over the next week all of our electronics began to slowly fail. I asked a lot of questions about this and found out our surge protection wasn’t fast enough, that it only takes a tiny static charge entering a chip to damage the micro connections causing them to fail slowly. When I used to build my own computers I always wore a static grounding strap because of this same problem. So I understand how this super fast device would offer perfect protection if the lighting struck the power lines or breaker box, but I’m going to need an electronics expert not associated with the manufacturer to explain to me how it protects from a lightning strike that enters at the other end of the circuit and passes the devices before it arrives at the protector. Same thing with EMP charges generated inside a device connected to the circuit.
    I also wonder how they replicate HEMP and CME effects in a small lab setting, especially since we have no direct experience measuring these events when they have occured.
    I was surprised when I researched home protection lightning rod systems and found there was no evidence that they offered any protection from lightning at all.
    Here’s an odd thought, a client of mine had an old two story house with all copper plumbing. The plumbing had been hit by lightning 3 times. Wonder what HEMP/CME does in a copper plumbing loop?

    1. Ivy Mike ,,,,how about a short about lighting ,,years past at the hayyouranch#1 we had lighting problems ,i took the time to do some research ,lighting rods on home and barns came about to prevent fires in the days before things were wired ,in my research I came across books and pamphlets on the right and wrong way to install lighting rods and the grounding ,lightingrods and ground rods were put on standoffs to keep the heat off the house or barn from the strike ,we had problems with electric fences getting hit and taking out the fence power supply,we used loops of wire to make a choke to short the surge ,saw a house that was hit ,started at the yard light went in the house wiring and blew the sheetrock off the studs and started fires ,house needed a complete rewire ,i feel the only safe thing is to unplug things. I think that the gap in a breaker is insufficient ,we used three prong range plug on the well pumps ,solar panels are also a target ,even if not hit directly , we tryed using steel “t”posts set around the panels that stopped direct hits , but still lost the panels , I saw a hit once to a barbwire fence the wire glowed and was gone I was in a pickup it stopped running , but started back up ,that leaves your ears hurting ,,,,,,life with mother nature ,,,,,,,,,,,,,

    2. The surge protectors that you purchase at big box stores and plug your electronics into are not designed for lightening, only grid fluctuations. I know this from experience as I had all of my electronics on surge protectors when our home was hit by lightening. I had $3000 worth of electronics destroyed.

  7. Would an EMP affect and internal medical device Like a deep brain stimulator, a pace maker or insulin pump? If yes is there a device that can be purchased or made to protect the patients internal battery pack? If not With the electrical surge cause organ damage to the patient with internal medical devices?

  8. – Jeanne Doubet,

    To answer your questions, as best we know, Yes it would affect those internal medical devices. No, there is no protection available at this time. Yes, probably, although insufficient studies have been done. There has been a certain lack of available studies because of lack of exposure to EMP’s. Going from exposure to lightning strikes, though, is the best information available at this time. Sorry, I’m not much help, am I.
