I know the code says the clearance for open conductors from patios, decks, etc. is 3 ft. Is that from the actual structure? How about if someone is standing on the deck? How far from their hand reach is this? How about if they stand on the railing? I know that's a crazy questions, but I have a "service riser" I need to run and the weather head is going to be up above the patio of this house on the second story. If I knew how to post a picture, I would include it:)
