Yins guys are sounding pretty high brow so I might as well jump into the fray. One thing I think I've learned is that no matter how many times I tell lightning how it's supposed to behave, it never seems to listen. Ponder my thoughts and feel free to blast away at me. I won't feel hurt.
Lighting strike = single turn primary??
Area between lightning and house = air core??
House wiring roughly parallel to strike = loosely coupled, single turn secondary??
Main panel surge suppressor = sitting there whistling, doesn't know that the furnace ctl. board just blew up, again. Doesn't know that it's going to get blamed for not stopping a surge that didn't come from the utility.
OK, blast away, make it pithy & no bloviating. ( I'm watching waaay too much O'Reilly.)
