54.6-C.    Lateral Conductors

Lateral runs of conductors of 0-750 volts may be less than the clearances from center line and surface of pole, and from the surface of crossarm, as specified in Table 1, Cases 8 and 9, provided such conductors are suitably insulated and placed along the bottom surface of crossarms and are protected by wood moulding on impregnated fiber conduit of thickness not less than as specified in Rule 22.2.

Lateral runs of conductors of more than 750 volts may be less than the clearances from center line and surface of pole, and from the surface of crossarms, as specified in Table 1, Cases 8 and 9, provided such conductors are suitably insulated and are protected by impregnated fiber conduit attached to the bottom surface of crossarm.

The wood moulding or fiber conduit required for protection in accordance with this Rule 54.6-C shall extend along the arm to the outer position of any conductor in the run and in no case shall the covering be terminated within 15 inches from center line of pole.

The radial clearances between conductors, specified in Table 2, Cases 16 and 17 are not required between suitably insulated conductors in the same lateral run.

54.6-C.    Lateral Conductors

(1)    Conductors of 0-750 Volts: Lateral runs of conductors of 0-750 volts may be less than the clearances from center line and surface of pole, and from the surface of crossarm, as specified in Table 1, Cases 8 and 9, provided such conductors are suitably insulated and placed along the bottom surface of crossarms and are protected by wood moulding or impregnated fiber conduit of thicknesses not less than as specified in Rule 22.2, or are protected by plastic pipe designated as Type II, Schedule 40 in the standard specified in Rule 22.2-C.

(2)    Conductors of more than 750 Volts: Lateral runs of conductors of more than 750 volts may be less than the clearances from center line and surface of pole, and from the surface of crossarm, as specified in Table 1, Cases 8 and 9, provided such conductor s are suitably insulated and are protected by the impregnated fiber conduit or plastic pipe specified in Rule 54.6-C(1), such conduit or pipe being placed along and attached to the bottom surface of crossarm.

(3)    Extent of Run: The wood moulding, or fiber conduit, or plastic pipe required for protection by this Rule 54.6-C shall extend entirely under and along the arm to the outer position of any conductor in the run and in no case shall the covering be terminated within 15 inches from center line of pole.

(4)    Conductor Clearances: The radial clearances between conductors, specified in Table 2, Cases 16 and 17, are not required between the suitably insulated conductors in the same lateral run.
