I do not have a copy of NFPA 780-2004 which explains lightning protection procedures. Hope somebody can answer a few questions. I am connecting a lightning ground rod to a cross ontop of a church. The print specifies that the lightning ground wire be run INSIDE the building through emt and that the emt should be spaced 6ft from any other wiring or metal structure. It also says that the ground wire be #1AWG. Now first of all, I didn't think lightning protection was allowed to be run indoors. Nor does it even sound like a good idea. And the #1AWG seems a bit undersized. Anybody have any input on this?
