The proof test for any wire rope or cable assembly should apply a load of no more than 60% of the minimum rated breaking strength of the cable. Example: For 1/8 “ 7 X 19 GAC = 2000 lbs. min break X .60 = 1200 lbs. proof test load Application of a higher load than 1200 lbs in this example can cause permanent damage to the cable being used.
