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 750-22,500 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.
