Rule 54.6-C2

54.6-C2)    Conductors of 0-750 Volts: Lateral conductors of 0-750 volts may be installed with less than the radial clearances between conductors, specified in Table 2, Cases 16 and 17, and with less than the clearance from the 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. Such conductors when installed along the bottom surface of crossarms and protected by plastic pipe having the properties of the material specified in Rule 22.2-C shall be considered to be suitably protected and allowed in the climbing space.
