Rule 84.7-A

84.7-A.    Where Line Arms Only Are Involved (see App. G, Fig. 34)

The climbing space through the levels of conductors sup- ported on line arms only should be so located that the center line of pole is approximately midway on the side of the climbing space parallel to the crossarms. The horizontal dimensions of such climbing spaces, with widths measured perpendicularly to the conductors, and with depths measured from center line of pole and parallel to the conductors, shall be not less than those specified in Rules 84.7 -A1 and 84.7 -A2, except at angles in lines in which cases the widths of 18 and 30 inches may be reduced to not less than 16 ½ and 27 ½ inches respectively provided the horizontal separation of pole pin conductors measured parallel to the crossarm shall be not less than 18 and 30 inches respectively.

(1)    On Poles Which Support Communication Conductors Only: The climbing space for toll, trunk and other conductors not used for local distribution shall be not less than 18 inches in width and not less than 30 inches in depth.

The climbing space for exchange or local distribution conductors shall be not less than 30 inches in depth and not less than 30 inches in width, except that for conductors of 160 volts or less, which are used for exchange or local distribution service but which were originally used and placed as toll conductors of like voltage, the climbing space shall be not less than 18 inches wide.

In rural districts, the climbing space for exchange or local distribution circuits of 160 volts or less which are sup- ported on crossarms at the top positions of poles which support no other crossarms shall be not less than 18 inches wide and not less than 30 inches deep.

(2)    On Poles Jointly Used With Supply Conductors: The climbing space through the levels of communication conductors on line arms On poles jointly used with supply conductors, shall be not less than 30 inches in width and not less than 30 inches in depth, except that climbing spaces of the dimensions specified in Rule 84.7 –A1 may be used where the only supply conductors supported by the pole are on service drop clearance attachments as permitted by Rules 54.8-D2 and 54.8-D3.

84.7-A.    Where Line Arms Only Are Involved (see App. G, Fig. 84 Fig 84-3)

The climbing space through the levels of conductors sup- ported on line arms only should shall be so located so that the center line of the pole is approximately midway on the side of the climbing space and parallel to the crossarms. The horizontal dimensions of such the climbing spaces, with widths measured perpendicularly to the conductors, and with depths measured from center line of pole and parallel to the conductors, shall not be not less than those specified in Rules 84.7 –A1 and 84.7 -A2,

Exception    At angles in lines in which cases the with widths of 18 and 30 inches may be reduced to not less than 16 ½ and 27 ½ inches respectively provided the horizontal separation of pole pin conductors measured parallel to the crossarm shall be not less than 18 and 30 inches respectively.

(1)    On Poles Which Support Communication Conductors Only: The climbing space for toll, trunk and other communication conductors not used for local distribution shall not be not less than 18 inches wide and 30 inches deep in width and not less than 30 inches in depth.

The climbing space for exchange or local distribution conductors shall be not less than 30 inches in depth and not less than 30 inches in width, except that for conductors of 160 volts or less, which are used for exchange or local distribution service but which were originally used and placed as toll conductors of like voltage, the climbing space shall be not less than 18 inches wide.

In rural districts, the climbing space for exchange or local distribution circuits of 160 volts or less which are sup- ported on crossarms at the top positions of poles which support no other crossarms shall be not less than 18 inches wide and not less than 30 inches deep.

Rule 84.7-A

84.7-A.    Where Line Arms Only Are Involved (see Fig 84-3)

The climbing space through the levels of conductors sup- ported on line arms only shall be located so that the center line of the pole is approximately midway on the side of the climbing space and parallel to the crossarms. The horizontal dimensions of the climbing spaces, with widths measured perpendicularly to the conductors, and with depths measured from center line of pole and parallel to the conductors, shall not be less than those specified in Rules 84.7-A1 and 84.7-A2,

Exception    At angles in lines in with widths of 18 and 30 inches may be reduced to not less than 16 ½ and 27 ½ inches respectively provided the horizontal separation of pole pin conductors measured parallel to the crossarm shall be not less than 18 and 30 inches respectively.

(1)    On Poles Which Support Communication Conductors Only: The climbing space for communication conductors shall not be not less than 18 inches

(2)    On Poles Jointly Used With Supply Conductors: The climbing space through the levels of communication conductors on line arms On poles jointly used with supply conductors, shall be not less than 30 inches in width and not less than 30 inches in depth, except that climbing spaces of the dimensions specified in Rule 84.7-A1 may be used where the only supply conductors supported by the pole are on service drop clearance attachments as permitted by Rules 54.8-C2 and 54.8-C3.
