that one i'd consider very unlikely....
here's one that i learned that is even weirder....
i was designing power, data, and security for a horse barn.
(thoroughbreds. don't even ask.)
my electrical engineer, upon finding this out, wanted to know
if it was dairy or other type of barn... i said "what's the difference"?
here's the difference.... if everything is not grounded EXTREMELY well
in a dairy barn, the cows will not give milk, or will give reduced milk.
i figured i was just being twizzled, but he was dead serious. he said
that in a commercial milk barn, they will usually use a 20' chemical ground.
apparently, the problem is widespread enough that there is a firm
dedicated to the problem...

This is a major problem and is by no means limited to one firm looking into it. A horse barn is different than a dairy but I would certainly head the warning from your electrical engineer. You have a lot to read.
