54.9-C.    Conductor Material

All conductors of a rack group in the same vertical plane shall be of the same material.

(1)    Urban Districts: Conductors in rack construction in urban districts shall have a crossing not less than the equivalent of double braid weather-resistant covering.

(2)    Rural Districts: Line conductors in rack construction in rural districts may be bare conductors provided the vertical separation between conductors is not less than 12 inches and conforms to the requirements of Rule 54.9-D where greater separation is specified.
