According to -The American Elecricians' Handbook-, the standards are
from ANSI, and the 10 classes are classified by the circumference at
the top and at a point 6 feet from the butt.
Class 2 is 25 inches minimum top circumference, and the figure for 6
feet from the butt is dependent on the type of wood and the overall length.
Class 7 is 15 inches at the top, and 29.5 toward the butt for
Creosoted Southern Pine, 50 feet long.

Just have a quick question. What is the difference in the Class ratings of
telephone poles (ie. Class 2 and Class 7) and what is the reference for
these classes?
Thanks, Tim
