This 3-hour course is the first in a series of three courses about the mechanical design of electric power distribution facilities. This volume of the series addresses pole and crossarm loading and explains how to calculate the expected loads on poles and crossarms and how to properly size equipment for the loads.

The course is divided into seven short chapters. The course begins with an overview of pole loading issues and then describes horizontal moments on poles and strength requirements for poles. Determination of maximum allowable span lengths are explained and calculations are provided for vertical and horizontal loading of crossarms.
