Precisely. NEC is not applicable outside USA. It may not even apply in
USA for
antenna feeders & non-mains voltage lines such as for a rotator, for all I
know.
Without specifically suggesting to PY4RO what to do, I posted relevant
experiences
in a high rise environment with what I suspect are even more stringent
regulatory
requirements than in Brasil.
I would not be surprised that the objection to his running lines down the
lift shaft is
baseless. It is also possible that PY4RO has done it in a way that is
wrong. My
guess is that both may apply.
Perhaps my post should have suggested that PY4RO seek relevant suggestions
locally, or to have sent it to him directly. Towertalk seems too
US-centric, IMHO.
