Rule 83.4
83.4 Bonding
When
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 21.3-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 purposes of this rule, communication
messengers and guys are those which support Class C Circuits (see Rule 20.5)
and those Class C Circuits which are used for television transmission.
When
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 to the 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 22.2).
Note: Bonding of communications systems owned by electric utilities to other communication systems, while not required, is acceptable by mutual agreement between all parties.
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.
(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 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.

Rule 83.4
83.4 Bonding
Where separate communication messengers, or guys, or both, of the same or different ownership, are attached tot the same pole, and they are in proximity to electric supply circuits (see Rule 21.3-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 20.5) 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 22.2).
