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.

84.4-C1b)    On Brackets Attached to Crossarms: The radial clearance for communication Line conductors supported on brackets or extensions attached to crossarms 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 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 (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 supported 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. 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.

Final Version

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.
