Rule 54.6-D

54.6-D.    Vertical Runs

1)    Vertical Runs: Vertical conductors installed as specified in this Rule 54.6-D are known as Vertical Runs.

2)    Runs Less Than 18 Inches From Pole Centerline: Vertical conductors may be installed with less than the radial clearances between conductors, specified in Table 2, Cases 16 and 17, and on the surface of poles or less than 18 inches from center line of pole provided such conductors are suitably insulated and covered throughout by a suitable protective covering.  (See Rule 22.2 for the definition of suitable protective covering.)  the plastic pipe or U-shaped moulding specified in Rule 22.2 shall have a minimum wall thickness of 0.15 inches.  This protective covering is not required over suitably insulated vertical conductors in metal conduit attached to metal poles, towers, or other structures provided conduit and structures are metallically connected and effectively grounded.

3)    Runs 18 Inches From Pole Centerline: Vertical conductors may be installed with less than the radial clearances between conductors, specified in Table 2, Cases 16 and 17, and at a distance of more than 18 inches from the center line of any pole provided that such conductors are suitably insulated and covered by suitable protective covering or by securely supported impregnated fiber conduit without metal conduit.  Such conductors shall be located outside of the climbing and working spaces and shall not pass between conductors of different ownership except between the pole pair and at a clearance therefrom of no less than 6 inches.

4)    Option: In lieu of the foregoing vertical conductors may be installed as unprotected conductors, as specified in Rules 54.6-A and 54.4-D9.

5)    Runs Within 8 Feet Of Ground: Vertical conductors installed as specified in Rules 54.6-D(1) and 54.6-D(2) and which extend within 8 feet of the ground shall be treated as risers.  Runs which terminate in the top of the runs may extend within 8 feet of the ground but not less than 6 feet of the ground without being treated as risers.

6)    Runs Encased In Grounded Metal Covering:  Vertical conductors where encased in grounded metal conduit, sheath, or shield, shall be treated as risers.

3)    Runs 18 Inches From Pole Centerline: Vertical conductors may be installed with less than the radial clearances between conductors, specified in Table 2, Cases 16 and 17, and at a distance of more than 18 inches from the center line of any pole provided that such conductors are suitably insulated and covered by suitable protective covering or by securely supported impregnated fiber conduit without metal conduit.  Such conductors shall be located outside of the climbing and working spaces and shall not pass between conductors of different ownership except between the pole pair and at a clearance therefrom of no less than 6 inches.

5)    Runs Within 8 Feet Of Ground: Vertical conductors installed as specified in Rules 54.6-D(2) and 54.6-D(3) and which extend within 8 feet of the ground shall be treated as risers.  Runs which terminate in the top of the runs may extend within 8 feet of the ground but not less than 6 feet of the ground without being treated as risers.

6)    Runs Encased In Grounded Metal Covering:  Vertical conductors where encased in grounded metal conduit, sheath, or shield, shall be treated as risers.
