§ 2587.3. Conductor Location.

(a) Lead-in or aerial-drop cables from a pole or other support, including the point of initial attachment to a building or structure, shall be kept away from electric light, power, Class 1, or nonpower-limited fire alarm circuit conductors so as to avoid the possibility of accidental contact.

(b) A separation of at least 6 feet (1.83 m) shall be maintained between communications wires and cables on buildings and lightning conductors.

(c) Where communications wires and cables and electric light or power conductors are supported by the same pole or run parallel to each other in-span, the following conditions shall be met:

(1) Where practicable, communication wires and cables on poles shall be located below the electric light or power conductors; and

(2) Communications wires and cables shall not be attached to a crossarm that carries electric light or power conductors.

(d) Indoor communications wires and cables shall be separated at least 2 in. (50.8 mm.) from conductors of any electric light, power, Class 1, non-power-limited fire alarm, or medium power network-powered broadband communications circuits, unless a special and equally protective method of conductor separation, identified for the purpose, is employed.
