Original Version
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 conductor tension is held by cantilever strength of pin–type insulators and pins, double insulators and wood pins or single insulators and steel pins shall be used. Each line conductor shall be tied or fastened to both insulators, or the single insulator, to prevent slipping of the conductor under maximum working tension with a safety factor of 2 for 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 tie wires, or equivalent fastenings, will be considered as meeting the strength requirements of Rules 47.4 and 47.5 for conductor tensions up to 2,000 pounds per conductor.
