General Order 64
Data are presented in this appendix in the form of curves, showing minimum conductor sags allowable under the rules. As set forth in Rule 14, Section I, these are minimum values that will give the required safety factors and hence do no purport to represent current practice.
Other curves helpful for sag and clearance calculations are also given with examples of their uses.
