Construction 5.1 Locate the riser and spare duct according to Figure 1. If it is necessary to install a second riser (single phase only) on a pole, locate as indicated. 5.1a No more than 2-single phase or 1-three phase primary risers shall be allowed on a pole. 5.1b At ground level, the pole's circumference cannot be more than 45% encircled with risers from all utilities.

C2021

Revision 1 Page 5 of 11 Cables that are not to be immediately terminated shall be left individually coiled, with adequate length to apply a termination & connect to the primaries, and supported above the steel riser pipe. Minimum safe bending radius for the cable is 12X cable diameter. Coils left above the riser shall have a 36" diameter to avoid cable damage. If the cables left coiled above the riser are not of adequate length to connect to the primary, they shall be the contractor's, installer of the cable, responsibility to replace. Surge arrester leads should be kept as short as possible to maximize protection. Riser Grounding (See C5000 for more grounding details) 5.5a Bond all steel riser pipes to pole ground. Note: Grounding bushings may be used as an alternative to the U shaped pipe ground connector. If cast iron slip couplings are used, the steel sweep bellow ground shall have its own ground connector connected to the pole ground and rod. To prevent theft and vandalism the ground wire molding shall be stapled every 6". In NSTAR south locations, a bare 1/0 copper ground wire shall be installed, in the trench, from the riser to the first pad or pull box ground ring. In 4800 Volt delta primary areas, do not connect the arrester grounds to the secondary/system neutral. See C4402 for more details

Seal any gaps between the cable and the riser cap or adapter with duct seal. Any unused ducts shall be capped. Minimum 45' pole size is preferred, however, 40' poles may be utilized where clearances allow.
