Forgive me if this has been covered, but I couldn't find the archives. I'm building a barn and want a weather vane on my cupola. What is code on grounding it? Several people have said we don't get enough lightning here. I don't buy that. My guess is to treat it as a lightning rod, right? If so what is code on that? I'd like to get it right as I'm installing the cupola rather than after. Thanks Joel
