Original General Order 95
Supply Lines or Communication Lines Crossing
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. Splices and taps should not be made in spans adjacent to such crossing spans if the crossing span is not dead ended. Splices or taps in spans adjacent to a Grade" A " crossing span shall, if practicable, be placed nearer to the crossing support than the nearest conductor crossed over. This rule is not intended to prohibit splices or taps on the free ends of conductors which are dead ended 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 the Railroad 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 A WG copper wire.
