Grounding Issue > New Home
Hello,
We are building a lake house in an old barn style that will have a cupola on the roof with a copper finial. Under the roof (inside the house) the finial will have a metal face plate. How do we best ground this (assuming we have to as this will be the tallest point on the home). What type of wire, and it is safe to run the wire down through the walls of the home then into the ground, or should the ground wire be run on the outside of the home? Or is another option putting a lighting rod on the chimmney? Thanks much!:confused:
