There is another discussion group, of mostly Electricians, and electrical
inspectors, that has a huge searchable base of case history inquiries and Q and
A, very similar to Tower talk, only oriented to electricians and NEC. There
are a number of threads relating to outside structure grounding, as in towers,
and lamp posts, and related issues with to ground, or not to ground rebar
cages, Grounding/Bonding, etc. There is an efficient site search tool to seek
out specific topics. Check out:
All the best,
