Rule 84.6-E

84.6-E.    Risers

Risers of wires or underground cables shall be encased in securely grounded iron or steel pipe (or other covering of equal strength) from the ground line to a level not less than 8 feet above the ground line.  Risers from underground cables of Class C circuits may be encased in plastic pipes or in plastic U-shaped moulding, as provided in this rule, in lieu of the grounded iron or steel pipe required by this rule.  Such plastic pipe shall be of material as specified in Rule 22.2-C with a minimum nominal pipe size of 1 inch and with a minimum impact strength equal to 2-½” nominal EPC-80-PVC plastic pipe.

Risers shall be covered by a suitable protective covering as defined in Rule 22.2, where within a vertical distance of 3 feet above or 6 feet below the level of unprotected supply conductors supported on the same pole or structure.

Vertical risers where within both a 6-foot radius of another pole supporting supply conductors and within a vertical distance of 3 feet above or 6 feet below the level of any unprotected supply conductor shall be covered.
