General Order 95

Section X

Supply and Communication Lines in Line Crossings or Conflicts

103.1    Prevention of Conductor Breakage and Burning of Supports

A.    Splices and Taps

(1)    Splices in Crossing Spans, Mutual Consent: Splices shall not be made or permitted in crossing spans where Grade “A” construction is required unless the mutual consent of all parties involved in such spans is obtained. Nothing contained in this Rule 103.1–A1 shall be construed as requiring that splices be made, or as granting authority for or permitting the making of splices in such crossing spans without the consent of all parties owning or operating overhead lines involved in such crossing spans.

(2)    Splices and Taps in Crossing Spans: Splices and taps shall, as far as practicable, be avoided in crossing spans where Grade “A” construction is required. If it is impracticable to avoid such splices, they shall be of such type and be so made as to have a strength practically equal to the conductor in which the splice is made. 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 in the crossing span.

Note:    Revised February 3, 1959 by Resolution No. E–1011.

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.
