Does the NESC require "Raptor
NESC Rule 011, Scope, addresses the scope of the
NESC document. Although not specifically addressed in the Rule 011,
the NESC does not cover easements, environmental protection, raptor
(bird) protection, FCC regulations, FAA regulations,
electromagnetic fields (emf), or
construction cost issues. These items are either covered by other
standards or they do not present a safety concern and therefore
they are not addressed in the NESC. Two documents that provide a
wealth of information on Raptor and Avian protection are Suggested
Practices for Avian Protection on Power Lines: The state of the Art
in 2006 and Migrating Bird Collisions with Power Lines.
These documents are available from the Avian Power Line Interaction

a conductor and non-metallic or metallic bird spikes on a crossarm. NESC Rule 012 requires the use of
accepted good practice when specifics are not addressed in the

direction from line conductors to supports and vertical or lateral
conductors, span, or guy wires attached to the same support.
