Canada does this too. I've had an 'inspector' tell me that I could not ground my windmill tower, had to bring the ground in through a wire into the house and tie it to the ground in the electrical panel because I was allowed only on ground point in my installation.

Totally nuts. I get why they want only one ground from a safety perspective but to bring a potential source of a lightning strike into your electrical panel when it can be safely deflected outside the house is insanity to a degree that I'm not convinced it shouldn't be criminal.

Anyway, I refused, they kept on harassing me and eventually (after a year or so) left me alone. I told the guy I'd do it if he would inform my insurance company of the change he requested in black and white, but that of course he would not do. I suspect he became an electrical inspector by following some course, not because he actually understood the first thing about physics.

Highly annoying.

That's very strange. Could you not just sink a copper pole into the ground the requisite distance? Do inspectors not have a method for inspecting the actual "ground" that grounds are connected to? Many questions...
