54.4-D6b)    More Than 750 Volts:  Where conductors are dead ended on a pole in vertical configuration, the energized portions of such conductors shall have clearances of not less than 15 inches from the surface of pole for voltages between 750 and 7500 volts and 18 inches from the surface of pole for voltages in excess of 7500 volts.  Where conductors of more than one circuit are dead ended on a pole in vertical configuration, increased pole clearances are required as follows:

All energized portions of conductors of a circuit dead ended in vertical configuration below any other circuit on a pole shall be maintained at a clearance of not less than 3 feet from the surface of the pole for conductors of more than 7500 volts; and

Not more than two conductors of a circuit of 750-5000 volts shall be attached directly to a pole in vertical configuration without the use of crossarms.  The number of conductors of a circuit of more than 5000 volts so supported on a pole is not limited.  Branch circuits may be taken from such construction without the use of crossarms provided a climbing and working space as specified in Rule 54.7 is maintained.

54.4-D6b)    More Than 750 Volts supported on climbable poles:  Where conductors are dead ended on a climbable pole in vertical configuration, the energized portions of such conductors shall have clearances of not less than 15 inches from the surface of pole for voltages between 750 and 7500 volts and 18 inches from the surface of pole for voltages in excess of 7500 volts.  Where conductors of more than one circuit are dead ended on a pole in vertical configuration, increased pole clearances are required as follows:
