|OK, I get your drift - but telephone companies run floating lines into

|the power company put surge arrestors in the transformers and/or in the
|house?

Yes, but the telephone company doesn't have to worry about connections
that get wired up to all the electrical appliances in the house. I
think capacitive transfer will probably raise the potential of the
ground wire should the power line get a direct hit, making all grounded
frames, like fridges, live.

I remember a page in the phone book, where I grew up, warning against
using the phone in a thunderstorm. Wonder if they still have that
page.
