Documentary “grid up power down” hosted by Dennis Quaid was enlightening.
Prepping for impending grid outage

Truth!!!! prepare to backout all windows
agreed.. Living in L.A. Baldwin Hills during the quake. Had to travel 10 miles for water. cant believe it's been 30 years. They are way overdue for another

IMO if EMP is big enough to take your home electric system that can only happen if there is a nuclear blast your within the fallout zone. You be better off just being vaporized then attempting to survive after a full nuclear exchange between 2 super powers. Even if you are off-grid and have EMP proofed there will be millions of starving people looking to take everything you have. You can only defend a stationary location so long eventually they will overcome any defenses you have. Why bother with spending extra money on EMP proofing I think it's more a gimmick like selling bomb shelters were in the 1960's.

You just need to be ready to defend what is yours.

If you look at studies of the black death in the middle ages, you will find that most economies continued to function as best they could, and that in general, things did not run amok, relatively speaking. Those scenarios are vastly more extreme than what have been presented to the populations recently. Modern perspective aside, this seems like a way to consider the present more positively. Not that I don't have my own strong opinions on the present....in a negative way....
I already got one.You just need to be ready to defend what is yours.

I'm not prepping for an EMP event or any other event that may take the grid down for 6 months or more. I'm prepping for the next ice storm. I've already been through 2, each resulting in lost power for more than a week. We installed a standby generator after the last one. However, we'd be lucky to get 5 days from the generator before running out of propane. In the next few weeks, I'll be adding 20 KWH of batteries to my home system. I'm hoping to convince the neighbor to follow, so we can convert the generator to 2 wire start and not run 24 hours a day.

The United Healthcare hack is the current serious threat to society.
"Grid down scenario" is the #1 reason we invested in all this solar gear.
Need electricity to operate the well pump & refrigeration, among other things.
(Reason #2 was to reduce the monthly electric bill)
Hurricanes are the main reason for prolonged grid outages.
Have been through a few in the last 7+ decades of living here.
Service is usually restored within 2 weeks or less.
The next reason is DUI drivers knocking down power poles in our rural area - power is restored quickly: (less than a day)
Not worried about man made EMP, but this solar cycle might send some unwanted energy our way:
I remember 30-40 years ago a solar event had the tropical night sky glowing bright red here.
Very unusual at this latitude.
I have implemented UL 1449 surge protection because of the amount of lightning strikes here during Summer, hope it helps w/ induced energy on the grid side of our connection.
We don't sell back, so the solar electronics are not going to see anything massive coming from the grid.
Also implemented some of the Motorola R56 standard grounding & bonding (built a halo system) around the building that has the Schneider electronics in it.
As others have mentioned, letting vast numbers of foreign soldiers and terrorists in to the country will eventually result in attacks on infrastructure and institutions, so in terms of probability of extended grid down reasons, this might be higher than hurricanes now.
A few years ago, I went on the public tour of the Grand Coulee dam.
The tour is much less extensive than before, due to security concerns.
But they did show us the system that is designed to prevent a vehicle from driving on to the dam, it would shred a big truck that hit it at speed, very impressive.
added idea - if the North America grid is significantly damaged, and down for a long time, the data centers providing Internet, cloud and storage will shut down.
The one I worked at had about 8MW worth of giant gensets, but only "day tanks" of
Diesel, requiring a tanker refill. Twin 24 cylinder, quad-turbo Diesels are thirsty.
So I'm buying one of those "Starlink" contraptions, reasoning that somewhere on the planet,
there will be a functioning net.
Starlink and a 1951 HF tube-type receiver will keep me connected to the world, I hope.

But a mine, underwater or floated (possibly remote controlled) into the dam could do enough damage that the water flow through the breach would finish the job."Grid down scenario" is the #1 reason we invested in all this solar gear.

Don't give anybody any crazy ideas.

My uncle was in the Army at the time of the Davy Crockett. He was trained to shoot nuclear tipped artillery. He has a picture standing next to one of the guns at the training center he was sent to. He said they never fired any on a test range I'm sure they sent 100's of personal to the training school he was deployed to Germany late 1950's early 1960's I believe he was drafted.You just need to be ready to defend what is yours.

Just curious, why do you think that your solar electronics aren't at risk just because you don't sell back. If your inverter/solar has a grid connection, then it will see whatever the grid sends out. Even if they just share a ground there may be some risk.
Yes, when the grid to inverter breaker is closed, grid events are seen by the inverters.
I open the breaker in cases where risk is present.
Even though I find the web site
virtually incomprehensible, it is possible to obtain some advance warning of solar events there,
so I have time to act.

What's in a title?
Thanks for this.
I have my grid breaker open, hopefully for the season, but the ground is still shared.
Wonder how large the risk is.

1000v per mm to complete a circuit on your open breaker.Thanks for this.

How far apart are the contacts inside there?
