Electrical question. Who knows about EMP/whole house lightning protection? Is it Worthwhile?

I found the Intermatic IG2240-IMSK Surge Protective Device. https://www.intermatic.com/Product/IG2240-IMSK

They have a modular system where individual modules are replaceable by the consumer (like printer cartridges) if there is a lightning strikeView attachment 4791496

Btw they have a 50k warranty for connected devices

That looks interesting. No snake oil advertising, and it looks like you might be able to get the modules through Lowes or Home Depot if you don't have a spare on hand.
 
Good for him; I have trouble trusting anyone hawking their own products with their own "studies". From personal experience and knowledge of many sites (with EMI, RFI and many, many lighting strikes), you need both site and device protection. And the only thing that's going to protect you from an EMP is to build a giant faraday cage around your house and disconnect it from the outside. And I had to LOL at clip on ferrites stopping an EMP. EMI/EMP gets into everything that makes even the poorest conductor, unless there is a better path to ground. Ferrites may help with noise on the wire, but they're not going to stop an EMP.
Dr. Bradley is a real scientist actually an electrical engineer with a Ph.D. He published a book on EMPs some years ago that reads like a science book. https://smile.amazon.com/Disaster-P...fix=dr.+arthur+bradley,stripbooks,119&sr=1-19

In his YouTube videos, he actually tests equipment that he sells on his website. And watching those videos reminds me of high school physics classes as they can be boring. He's the real deal in every regard. You can email him from his website and discuss EMP topics and concerns- I've done that.
 
Ah, the age-old lightning protection debate! EMP and whole-house lightning protection can be a mixed bag. If you're in an area prone to thunderstorms, it might be worthwhile for peace of mind. It's like an insurance policy for your home's electrical system, but it depends on the frequency and severity of storms in your area.
By the way, if you're in Ottawa and need guidance on high voltage electrical setups or lightning protection, I've heard good things about High Voltage Electrical Contractor Ottawa. It might be worth reaching out for expert advice. They can really help navigate the specifics and ensure your home's safety during electrical storms.
Remember, it's all about finding the balance between necessary precautions and practicality. Stay safe!
 
I own and operate an electrical business based out of Atlanta.

With all new homes, panel changes, or anytime we pull a permit, we need to add whole house surge suppressors to the system. It's evident that they can/do work. Your grounding system needs to be installed correctly for it to be most effective. We've done quite a bit of lightning repair on homes that didn't have a whole house surge suppressor and have never done any lightning repairs on any house that has a whole house surge suppressor.. Just about any licensed electrician can give you some advice on this with recent field experience. As for EMPs, you're on your own.

The one thing that a whole house surge protector can do efficiently is handle surges coming into the home via the power lines. But what can happen (and has happened to me) is that a lightning strike near the home can induce currents in your existing house wiring that bypasses the power line surge protector. In my case there were no point of service surge protectors at the computer/TV, satellite unit so the lightning struck not far from my house, induced house wiring currents and took out a couple thousand dollars worth of stuff. Remember this for electronics --- lightning can destroy PN junctions, etc. in solid state devices pretty easy (e.g., power supplies) and they'll blow at the drop of a hat to protect the fuse.

At the old house we lived in, I lost tvs in our bedroom twice to close strikes. Something about that circuit, maybe proximity to the tall pine lightning rods in the yard.
I put the last tv behind a small battery backup unit and it was problem solved.
I now have all sensitive electronics running behind units. Seems like cheap insurance.

They can handle the surges coning in through the "back door" too. The issue is that there are likely other electronics plugged in before the surge makes it to the panel. Having the expensive electronics plugged into a power supply with surge protection is really the best way to keep everything protected.
