Waste of money; a nuclear HEMP can fry low voltage electronics at the circuit board level even if they are not plugged or powered on. For a shunting to ground device like that one to have a real chance of working you'd have to have multiple of those shunts in your car, one on each sub circuit in the vehicle.
IF you believe that device is going to protect your vehicle against a nuclear H.E.M.P you'd have to believe that you could stop emp damage to your car just by tying the negative and positive battery connectors together. Now if you want to believe that you'd save $329 by buying the similar $60 devices here: T.R.A.P.-B EMP Vehicle Protection  And here's their cigarette lighter plug shunt version https://shop.cavestock.com/shop/t-r-a-p/  |

This was1962, and I assume there were plenty of televisions, radios, cars, and electrical appliances in use on Hawaii. But there was apparently no damage to any of those things. A few streetlights went out, some 1962 burglar alarms went off, and a single microwave link (again - a 1962 microwave link) was “damaged.” I would guess that a single thunderstorm has produced more damage to those same systems. The other example cited was a Russian test above one of the ‘stans, also in the 1960s.

Quote HistoryQuoted: Three wires. My understanding is it shunts positive, negative and body together when the EMP overvoltage happens. Once the event passes it returns to normal. This should prevent voltage differentials across sensitive electronics that would kill them. So, this will protect the entire vehicle? What about stuff inside the vehicle? I am kind of ignorant of EMP and how it works. |

You know all you have to do it turn it off. In testing vehicles run just fine during an EMP event by being turned off. about 85% of running vehicles had no problem during an emp event. IT seems like a great way to empty your wallet to protect it from emp.

I’m open to being convinced, but I’m going to need some documentation, which seems to be conspicuously absent from these threads. First, let's discuss lightning. Most items damaged by lightning are not subjected to the lightning bolt itself. They are damaged because of an induced high-voltage spike in the wiring system they are connected to. So if lightning hits a tree in your yard, a spike is induced in the power lines and/or wiring in your home and might damage your TV etc. EMP is basically the same thing at an altitude that lets the electromagnetic wave generated by the nuclear bomb radiate to as much infrastructure as possible. But the local effect is the same as the local lightning bolt, you get a high-voltage transient spike induced in any conductors the wave hits. That's why the grid is so susceptible, in theory, it's a giant antenna the wave will theoretically hit 'at the same time'. The smaller the device, the less energy it can absorb, although it's components may also be more sensitive. There are several mitigation methods of varying usefulness. Placing a phone in a metal box will certainly reduce the amount of EMF it sees, but of course, it's not doing you any good as a phone at that point. A faraday cage isn't that useful if it has power wires running into it or communication wires. The device in the OP is a 'lightning protector', I typed it like that because nothing is really going to protect any electronics from a direct lightning strike. So what does it do? It CAN shunt the energy of a smaller induced spike like the local lightning strike scenario above. There are several different types of these, but they all basically function as a device which is only conductive ABOVE a specified voltage. They are connected from line-to-line or from line-to-neutral or line-to-ground or all of those. As soon as the voltage rises above their threshold, they turn into a short circuit and shunt the spike to common/ground. To my knowledge, no air-detonated tests have been done, so it's all 'theoretical' until that happens. |

Quote HistoryQuoted: I'd love to hear your opinion on what it would take to properly protect a home and vehicles from large EMP devices. Would basic shunting at the breaker box protect most home electronics? Quote HistoryQuoted: Quoted:Dude, return it. I design this stuff for a living. I'd love to hear your opinion on what it would take to properly protect a home and vehicles from large EMP devices. Would basic shunting at the breaker box protect most home electronics? This magic box is under-rated at best, snake oil at worst. There are 2 basic methods to protect against over-voltage: TVS and MOSFETs (with appropriate trigger circuitry), and sometimes both. I use some pretty hefty TVS diodes, but I have no illusion about them clamping down a lightning strike. In fact, I've had equipment struck by lightning, and the expected results are what happened; stuff fries beyond use. Fun fact: lightning doesn't even have to hit the machine: it can just strike close. A strike close enough can "destroy" the memory of the modules and micros, leaving you with dead electronics. Whomever pointed out the 3 wires being BS, one being "ground" are 110% correct. Automotive systems do not have, for all intents and purposes, an earth ground. Let me clarify that: modules can have multiple "ground" circuits, some are digital, some analog, some chassis. In the end, they all go to chassis though (comm lines not withstanding, but those are not referenced as "ground"), but some go through filtering and/or protective circuitry. As far as earth ground, no. In fact, your tires make GREAT insulators. Unless you are dragging a grounding strap/chain (like forklifts do), then no, you have no ground. In fact, your vehicle can act more as a capacitor than a conductor to ground. What that 3rd wire is supposed to do is non-existent. Then, the website says it will protect your home as well. All of your home. Umm, ok, homes are not +12VDC systems. Actually, you SHOULD get a main panel surge protector. I have them installed in my house and office main panels. I still use surge protectors at point-of-use, and of course my UPS for my PC/internet equipment have surge protection built in. To protect your vehicles from EMP would require far more research, EMP theory (and it is just that: theory), and LOTS OF $$$ to do. BUT, if I were so inclined, I would just ground my vehicle when parked and call it good. Driving DURING and EMP event, if it did attack the vehicle, there is no magic box that will do anything to help. From what I understand of EMPs, they are low voltage, high current. You would have to be VERY careful in designing an protective circuit to have little resistance, such as utilizing diodes with extremely low forward voltage. If you are honestly that worried about an EMP, buy a mechanical diesel vehicle. ETA: What would I do to protect my home from EMP? First, I would have some hardware in place: Electronically controlled circuit breakers/isolators from main, a computer (analog or digital) system for DETECTING an EMP, and then a mechanism that will tie both L1 and L2 in the panel to earth ground (after making damn sure I have a good earth ground). Simply detect the EMP event, disconnect your home from the grid, tie L1 and L2 to ground, ride it out powered down. Basically, the same exact thing a UPS does, but instead of battery backup, it grounds everything. My running theory is no potential between your system and ground means no voltage, means no damage. Again, EMP effects are all, in practice, theoretical. |

Whereas over the US the density of the transmission system is exponentially higher, thus a much larger "antenna" to suck up the HEMP pulse. |

Quote HistoryQuoted: If emp strikes..I don’t think my vehicle running will make much of a difference ETA...beat..a few times...I was late to the party...  This is my opinion. I would like to have an option of a running vehicle but more than likely it won't matter. If your that scared pick up a vehicle with an old diesel motor that is reliable. No spark plugs and the fuel pump is driven by the motor. You only need two things once it is running, air and fuel in the right mixture. Just be aware that most if not all of these engines will draw "noise attention" unless 87% of the US is dead. I guess the biggest question is what type of EMP are we going to be hit with? Low altitude EMP, much more damage to localized stuff but on a broad scale not a big area (fingers crossed for Shitshow, San Fran, the Big Apple, or a few other locations; no offense to people stuck behind enemy lines though). High altitude EMP, really wide spread damage but they determined that most vehicles would run, might have a dreaded check engine light but not "totally out of the game." A high altitude EMP would take down power grids as the long bundled wires we have strung out across the US would be very susceptible to this, look up the Carrington event as an example. I think a study done like 20 years ago determined that if they did one of these over the central US, the US would be divided in half. Probably 50% or more would be dead within the year due to food shortages and things that happen during hard times. The long term goal might be to have a few solar panels hidden in a bunker (aka EMP protected) with everything you need to have a functional solar electrical source for everything you NEED to power. I would love to be able to store a big enough system for my entire house and an EV if I had one. The reality is I would be a target if I left my lights on. I need enough to power maybe a small refrigerator to store food I got (hunting or farming) but most likely I don't see the grocery store as being fully stocked....except maybe with criminals looking rob someone. If you have medical equipment, add that on. I would look at low power cooking devices and a few fans. We lived for thousands of years before A/C and heat, and it would suck but you can live. I probably would have a room for a portable AC unit for the really bad times and hope I calculated my solar power needs enough to make it work. Live in the basement in the winter and use the earth as a heat source though it would be cold still and a fireplace would come in handy. |

The hard part is going to be EMP protecting the very long supply chain to get the oil out of the ground and the gasoline into your car.
As an example: Florida. Following a "little" and "temporary" disaster as a bit of windy and rainy weather* the people of Florida run out of fuel very fast, within days. Imagine following a nuclear war? Think Pablo is going to the Chevron to pump gas for you (with a hand pump?). You think John is driving a truck cross-country from Long Beach to your neighborhood to bring more gas? *
