I was simply pointing out that "ALL electrical installations" seemed a tad
too broad.

Shielded/screened TP on utility poles? This is an insane thing to
do. It violates more rules than I want to even start to think about!
Telco wires are always connected to lightning arrestors at the
termination of the long run. (This is NOT always the same as the
demarc!) MGN is MANDITORY. This is not a do-it-yourself project.


I was unclear. I meant that do-it-yourself utility pole installations
were an insane idea. Telcos do deal with this routinely.
