National Wood Pole Standards Overview

The use of wood utility poles is guided by national standards, including ANSI 05.1 – Wood Poles, Specifications and Dimensions and the National Electrical Safety Code (NESC). Understanding these standards and how they are applied in the design and construction of overhead systems using wood utility poles.

NAWPC and the ASC O5 Committee have produced a three-part video series on national wood pole standards. Commentary is provided by Nelson Bingel, past chair of both the ASC 05 Committee and the NESC.
