General Order 95
Detailed Construction Requirements for Communication Lines
(Class C Circuits)
Where separate communication messengers, or guys, or both, of the same or different ownership, are attached to the same pole, and they are in proximity to electric supply circuits (see Rule 21.5-D), railway signal circuits or Class T electric railway or trolley circuits, such messengers, or guys, or both, shall be bonded together at frequent intervals (See Rule 83.4-A). For purpose of this rule, communication messengers and guys are those which support Class C circuits (see Rule 20.6) and those Class C Circuits which are used for television transmission.
Where bonding is required, the bond wire or bond strap shall have a conductivity of not less than No. 6 AWG copper wire, and shall be securely attached to the messenger or guy. Such a bond wire or bond strap may be attached tot eh surface of a pole or to the underside of a crossarm using metal staples, but shall in no case be attached to the top surface of any crossarm. Bond wires or bond straps placed in the climbing space shall be covered by a suitable protective covering (see Rule 22.8).
communication systems owned by electric utilities to other communication
systems shall not occur within 1,200 feet of an electrical substation without
prior consent of the supply utility.

and January 19, 1994 by Resolution SU–25.
A. Messengers on the Same Pole
(1) Bonds between Separate Communication Messengers or Guys above or below
Electric Circuits: Bonds are required between separate communication messengers
or guys, attached above or below electric supply circuits, railway signal
circuits or Class T electric railroad or trolley circuits on the same pole
line system, at all dead–end poles and at intervals not to exceed 1,320 feet.
Note: Revised October 9, 1996 by Resolution
(2) Bonds between Separate Communication Messengers Crossing Electric Circuits:
Bonds between separate communication messengers on the same pole line system
are required at the first pole on either side of the location where such messengers
cross over or under electric supply circuits, railway signal circuits or
Class T electric railway or trolley circuits.
(3) Bonds Not Required: Bonds are not required between communication
messengers or guys which are attached to the same pole by a common bolt.
B. Messengers of Different Pole Line Systems
Bonding is required between communication messengers or guys, or both, where the pole line systems intersect at a common pole.
