Well, if you have everything enclosed in a Faraday cage and run on batteries inside the cage, you are OK.

But now let's look at the real world. What do you reckon will happen when a power cord going from the local step-down transformer sends not the standard 120 volts into the equipment inside the cage but rather sends a couple of thousand volts?

How about when that step-down transformer that normally has a few thousand volts as input is subjected to a few tens of thousands of volts?
