Ground Wire for new Service Drop
I am upgrading my house to a 200 AMP.
This requires a new service drop and panel. The technician that came out and gave requirements says I need to run a ground wire that connects my natural gas line, to my water line, to a 8' ground spike and to the new panel.
He instructed me to have few as breaks as possible and to use #4 wire.
Ok, here is the question. I have un-shielded copper wire in #4 and want to know if there is any issue with me running this ground connection on the external of my home.
Or do I need to run it into the attic, and same question there is bare copper OK to run through an attic for grounding purposes. I have see in new home construction the bare copper done in this manner when used to ground the water to gas etc.
Thx.
