Rule 84.4-C1b
84.4-C1b)
On Brackets
Attached to Crossarms: Line conductors supported on brackets or extensions
attached to cross- arms shall be maintained at, or outside of, the outer pin or
dead-end positions on the crossarm with a radial separation not less than the
minimum pin spacing specified in Table 2, Case 15 (3 inches) from any other
line conductors supported by the same crossarm, except that not more than two
conductors on the same side of pole on any crossarm may be sup- ported on
brackets within the outer pin position and below conductors normally supported
on pins on the crossarm provided that all conductors concerned do not carry
more than 160 volts and the power transmitted does not exceed 50 watts and the
vertical separation between conductors so supported on brackets and those
attached on pins or dead ends on crossarms not supporting the bracket shall be
not less than 12 inches. The vertical clearances specified in Table 2, Cases 1
to 14 shall be provided between the conductor on the bracket and the conductor
level of any other conductors not supported on the crossarm to which the
bracket is attached.
This rule shall not be held to apply to clearances between
conductors of the same or similar circuits at or points of transposition.

Rule 84.4-C1b
84.4-C1b)
On Brackets
Attached to Crossarms: The radial clearance for communication line conductors
supported on brackets or extensions attached to crossarms at, or outside of,
the outer pin or dead–end positions shall not be less than 3 inches from any
other communication line conductor supported by the same crossarm as specified
in Table 2, Case 15, Column C. Not more than two conductors on the same side of
the pole on any crossarm may be supported on brackets within the outer pin
position and below conductors normally supported on pins.
There shall not be less than a 12
inches vertical separation between communication conductors supported on
brackets within the outer pin positions on one crossarm and the communication
conductors on another crossarm. The vertical clearances specified in Table 2,
Cases 1 to 14, Column C shall be provided between the conductor on a bracket
and the conductor level of any other conductors not supported on the crossarm
to which the bracket is attached.
EXCEPTION: This rule shall not apply to clearances between conductors of the same or similar circuits at points of transposition.
