Rule 84.4-D3

 

84.4-D3)    Colinear, Conflicting Or Crossing Lines (See Rule 32.3): Where two communication lines are colinear or otherwise in conflict or where a pole of one line is interset in another line at crossings, the clearances of Rule 32.3 and Table 1, Case 8, Column B may be modified as follows:

In applying any of the provisions of this Rule 84.4-D3 an unobstructed climbing space on each pole concerned shall be maintained with horizontal dimensions of not less than 30 inches square for conductors carrying m
ore than 160 volts and 50 watts, and not less than 18 inches in width and 30 inches in depth for conductors carrying lower voltage and power.

 

a)    Where Clearance Arms Are Used: Where clearance arms are used, on poles which support only Communication conductors, to support the conductors, to support the conductors of a coliener or conflicting communication line the clearance of such conductors from the center line of pole shall be not less than 15 inches for conductors carrying more than 160 volts and 50 watts and shall be not less than 9 inches for conductors carrying lower voltage and power.

 

b)    Where Clearance Arms Are Not Used: Communication conductors which in passing another communication pole unattached would be less than 15 inches from the center line of pole or less than 5 inches from the surface of pole shall be attached to the pole in accordance with the provisions of Rules 84.4C1c and 84.4D2 .
