Rule 54.6-F
54.6-F. Terminals of Encased Riser and Runs
Terminals of risers or runs shall not extend above the level of line conductors to which the terminal leads are connected except as follows:
Where the line conductors
are installed in vertical configuration in partial underground distribution, or where the line
conductors are dead-ended on the opposite side of the arms from the terminals
and no line conductors supported on the same crossarm and the same side of pole
extend past the terminals and no buckram construction is involved, or
Where conductors in excess of 7500 volts are installed in vertical configuration on crossarms, and the terminals are mounted on the same arms which support the conductors to which the terminals are connected.
At the upper end of vertical runs or risers on wood poles, any terminal or terminal fitting within distances from center line of poles less than as specified in Table 1, Case 8, shall be protected by a crossarm or wood block placed above it at a distance not exceeding 4 inches. The wood block may be omitted if the terminal or terminal fitting at the upper end of a vertical run or riser of 750 volts or less is on the same side of a pole as, and not more than 1 foot below a transformer or not less than 3 inches below the lowest conductor of a rack, and such terminal fittings shall be approximately centered in the vertical plane under the rack, or where the conductors of a vertical run or riser are enclosed in plastic pipe (see Rule 22.2-C) and do not terminate in a grounded terminal or terminal fitting.
Cable or conduit bends and the terminals of risers or runs of conductors of more than 750 volts supported on climbable poles or structures shall be arranged with as little exposed surface as practicable but are not required to be covered by a protective covering provided that no portion of the terminal or associated unprotected conductors are within the climbing space or within the clearance from center line of pole specified in Table 1, Case 8 (15 or 18 inches). All exposed grounded surfaces of such terminal fittings and bends of risers and runs shall be not less than 18 inches vertically above the conductor level, and not less than 2 feet radially from any conductor at the next conductor level, of unprotected conductors of another circuit which is entirely below the level of the circuit to which the riser is connected (see App. G. Fig. 61).
The terminal fittings of risers or runs of conductors of
0-750 volts installed on the surfaces of poles shall of be within the climbing
space and unprotected leads to or from such terminals shall not pass within the
climbing space but may have a clearance of less than 15 inches from center line
of pole (Table 1, Case 8) and less than 3 inches from the surface of pole or
crossarm (Table 1, Case 9). It is recommended that conductors from such
terminal fittings be suitably installed and, where practicable, carried as
protected lateral runs on the bottom surface of crossarms (see Rule 54.6-C)
In partial underground distribution (750-22,500 volts in vertical configuration
on non-climbable poles), energized portions of the terminals may be less than
the clearances from center line of pole specified in Table 1, Case 8, Column E
(15 or 18 inches) but shall be not less than 6 inches from the surface of the
non-climbable metal pole and grounded metal surfaces associated therewith.
The Vertical clearances between the lowest point of lead wires of a riser or
run (vertical or lateral) and the next conductor level below shall conform to
the requirements specified in Rule 54.4-C6.
