Rule 84.4-D4

84.4-D4)    Conductors Passing Supply Poles And Unattached Thereto: The center line clearance between poles supporting supply conductors and any communication conductors which pass such poles unattached shall be not less than 22 ½ inches (1 ½ times the clearance specified in Table 1, Case 8), except where the supply pole is within 10 feet of the pole on which the communication conductors are supported. Where poles of the two lines are less than 10 feet apart, clearances not less than as specified in Table 1, Case 8, shall be maintained.

Note    Resolution No. E-999, effective October 7, 1958, authorized that the 22 ½-inch clearance of Rule 84.4-D4 shall not apply to communication cable passing but unattached to a street lighting pole which is non-climbable, provided:

a)    Cable sheath and messenger are suitably insulated for the street lighting and other voltages involved.  Metallic poles, insulation to extend 3 feet horizontally from pole center line.

b)    Cable and Messenger to be mechanically protected from abrasion where necessary.

a)    Cable sheath and messenger are suitably insulated for the street lighting and other voltages involved.  Metallic poles, insulation to extend 3 feet horizontally from pole center line.

b)    Cable and Messenger to be mechanically protected from abrasion where necessary.

a)    From Non-climbable Street Lighting or Traffic Signal Poles or Standards:

Communications cables passing unattached to non-climbable street lighting and traffic signal poles or standards including mastarms, brackets and lighting fixtures, shall clear a radial distance of 12 inches as specified in Table 1, Case 10, Column B; except when the cable sheath and messenger are suitably insulated for the highest voltage involved and mechanically protected from abrasion where necessary. Such mechanical protection shall extend 15 inches in each direction along the cable from centerline of pole, standard, attaching mastarms or fixtures; whether passing above, below or alongside. The cable shall be installed in such a manner so as not to interfere with light distribution from lighting fixtures and shall not hamper workmen changing lamps or maintaining equipment.
