Rule 49.3-C2

49.3-C2)    Longitudinal Loads Normally Unbalanced:  At unbalanced corners and dead ends in Grades “A”, “B” or “C” construction, where the conductor tensions are held by cantilever strength in pin-type insulators and pins, double pins and insulators shall be used and each line conductor shall be tied or fastened to both insulators so as to prevent slipping of the conductor under the maximum working tensions with a safety factor of 2 under the temperature and loading conditions specified in Rule 43.

At changes in grade of construction and at end supports in Grades “A” or “B” construction where the conductors are not dead-ended and are supported on pin-type insulators, double insulators and pins with wires, or equivalent fastenings, will be considered as meeting the strength requirements of Rule 47.4 and 47.5 for conductor tensions up to 2000 pounds per conductor.
