Strikeout and Underline Version
Rule 54.4-C4c
54.4-C4c) Conductors of More than 750 Volts supported
on non-climbable pole: Where conductors of more than 750 volts are supported
in vertical configuration on non-climbable poles in partial underground distribution
at line terminations, angles, or corners, the following requirements apply:
Not more than three conductors of a single circuit of 750-20,000
volts shall be supported directly on the pole in vertical configuration without
the use of crossarms, Branch circuits may be taken from such construction
without the use of crossarms provided that conductors are supported on not
more than three sides of the pole, there being four sides (see App. G, Fig.
88);
The vertical separation between conductors shall be not less than the pin
spacings specified in Table 2, Case 15;
The clearance of conductors from surface of pole shall be not less than,
as specified in Rule 54.4-D2.
