What those worried about EMP are concerned about is the E1 pulse, which takes place in literally nanoseconds, far faster than surge protectors can react.

You have misunderstood Justa's comment. You are talking about high frequency pulses which everyone agrees are not going to be stopped by surge protectors. Justa was talking about the low frequency EMP and CME events that are much more likely. First, because low frequency EMP is much easier than high frequency. Second, because low frequencies are the only plausible natural event. Justa is exactly correct that surge protectors are more than adequate for those most likely events.

1. I already addressed Justa about this. He is correct about the Carrington Event-type of pulse (which is E3).

However...

2. If there is an artificial EMP, the E1 pulse will occur virtually instantaneously...and will leave our entire electrical/electronic infrastructure more vulnerable to E2 and E3 pulses.

I am presuming that we will have advanced warning of a Carrington Event-type of pulse, and be able to shut down some parts of our grid, and unplug as many devices as possible, so as to manually reduce the effects. There will likely be no such warning if we are attacked by another nation or a terrorist group that obtains a nuke on a rocket by some means. Proper planning would implement measures that would protect against BOTH natural and artificial EMPs - and my sole purpose on this thread was and is to let people know that the risks of either are not zero.

Personally, I prefer UPSs with solid state circuit breaker. I connect my power strips to a UPS.

CME is over-hyped though. It only loads up on exposed metal wire and cannot travel through walls to get into a house. The high tension cables and residential distribution lines (inc. transformers) have had over voltage protection for a long time. I have aerial electrical in my area so I have to take some precaution that buried electrical line users don’t.

Surprisingly the worst damage I took was when our power came back on after Irma. Apparently, some people on our grid did not disconnect their house circuit from the grid when they ran their generators. I.e. a separate breaker panel for the generator which is isolated from the house panel so they can shut off the main breaker and provide generator power to the house -not the street.

When electrical power was restored these ppls’ generator power was added on top of the line power. It was my misfortune to be up at 2am when the power was restored. I saw the street lights were on and went and turned off the generator and re-connected to line power (toggled generator panel breakers to Line Power and turned on the main breaker). Whack, there went one of the LED rows in my microwave’s display panel. I knew right away why. At 2am not many ppl on generator are awake to manually switch back to line power. If they haven’t shut off their main breaker they’re putting their generator output onto the grid. The expensive, automated generator systems are apparently few and far between in my neighborhood.
