General Order 95

Section XI

Supply Lines or Communication Lines Crossing over Railroads

113.1    Prevention of Conductor Breakage and Burning of Supports

A.    Splices and Taps

Splices shall not and taps should not be made in crossing spans where Grade “A” construction is required or where Grade “B” construction is required for Class C lines crossing railroads. Splices and taps should not be made in spans adjacent to such crossing spans if the crossing span is not deadended. This rule is not intended to prohibit splices or taps on the free ends of conductors which are deadended at the crossing span.

The provisions of this rule shall not apply to conductor splices which are made by any accepted standard method which has been proved by test before this Commission to develop practically the full strength of the conductor in which the splice is made.

B.    Supply Conductor Supports

In installing insulators and conductors, precautions shall be taken to guard against the possibility of arcs or leakage current injuring conductors or burning any wood parts of the supporting structure which would render the conductors liable to fall. In cases where two or more circuits are carried on the same poles and steel pins with wood crossarms are used, the insulator pins of different circuits, if bonded, shall be bonded independently of each other in conformity with Rule 53.4–A3 . The conductor used for bonding shall have a conductivity not less than No. 10 AWG copper wire.
