General Order 64

Detail Construction Requirements For Trolley Contact Lines And Feeders – Class “T” Circuits

86    Conductors.

(a)    The minimum size which shall be used for railway contact conductors on public streets or highways is No. 0 A.W.G. copper, or other wire of equal strength.  Other Class “T” conductors shall comply with Rule 63.

(b)    All overhead trolley contact conductors shall be so supported and arranged that the breaking of a single “suspension” or fastening will not allow the trolley conductor, or live span wire or current-carrying connections to come within 10 feet from the ground or from any platform accessible tot the general public.  This does not apply to feeder taps to or from trolley contact conductors.  (See Appendix E, Figs. 26 and 27.)

(c)    Trolley contact conductors of over 1500 volts, when in urban districts and not on fenced rights of way, shall be so suspended that if the conductor is broken at a single point it can not fall within 10 feet from the ground or any platform accessible to the general public.  (This practically requires catenary construction.)

(d)    All “third rails” carrying 750 volts and below shall be protected by suitable overlapping guards made of wood or other suitable material, except those rails located on fenced rights-of-way.
