Appendix > Cable Pulling Calculations > Maximum Allowable Pulling Tension with a Pulling Eye 
Version: 10.1 
The equation below calculates the maximum pulling tension if a pulling eye is attached to the conductor. Do not exceed this amount.
T_{max} = KA
Where: 
T_{max} = Maximum pulling tension (lb) K = 10,000 PSI for copper; 7,500 PSI for aluminum A = Area of conductor (sq in) 
The following table shows T_{max} for a standard single conductor (1/C) cable.
