Section VII


Detailed Construction Requirements For Trolley Lines

(Class T Circuits)


76.2    Use.

Where mechanical loads imposed on poles, towers or structures are greater than can be safely supported, additional strength shall be provided by the use of guys or other suitable construction.  Where necessary, guys shall be used wherever conductor stresses are unbalanced, as at dead ends or angles.

Where guys are used with poles or similar structures capable of considerable deflection before failure, they shall be able to support the entire stress, the pole below the point of guy attachment acting merely, as a strut.

Guys shall be attached to structures as nearly as possible at the center load.
  They shall be maintained taut and of such strength as to meet the safety factors of Rule 44.
