As an amateur radio operator for 60 years now I have been aware that a major worry vis-a-vis lightning is not so much the very rare "direct hit" that blows up the house, but the far more common "near miss" in which a very large electromagnetic pulse will spread at the speed of light whenever lightning strikes nearby. I have been taught that this pulse (EMP) will induce a substantial voltage on antenna structures but also on power lines coming into the house. In this context, how does having the neutral wire (grounded at the home's AC service panel) provide ANY protection against a voltage surge on the AC supply going into the house? I am confused about this despite much reading on this great web site.
