I should have said that for lightning, all the conduit needed to do was act as a lightning rod.

I doubt it is one continuous piece, but as long as sections make ohmic connections, I don’t see a problem. It’s just acting as a lightning rod.

Is the steel conduit one continuous tube? I doubt that.

Question: why is that necessary?
