General Order 95


Appendix B


Mechanical and Loading Data for Conductors

The tables included in Appendix B contain mechanical data for conductors commonly used in supply and communication lines. The ultimate strengths and other data for copper, steel and iron wires are those contained in specifications of the American Society for Testing Materials or are ultimate strengths based upon such specifications. For other types and kinds of conductors the ultimate strengths and other data used have been taken from manufacturers’ specifications.


The requirements of Rule 43 were used to calculate the loaded conductor conditions.
