Rule 54.4-C4b
54.4-C4b) Conductors of More than 750 Volts supported on climbable poles: Where conductors of more than 750 Volts are supported in vertical configuration directly on a climbable pole without the use of crossarms at the line terminations, angles or corners, the following requirements apply:
The vertical separation between conductors of the same circuit shall not be less than the clearances specified in Table 2, Cases 15 and 20;
The vertical separation between conductors of different circuits shall not be less than the clearances specified in Table 2, cases 8 to 13, inclusive;
Not more than two conductors of a circuit of 750-5000 volts shall be supported directly on 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 shall be limited to four. 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 and Rule 54.11 is maintained; and
The clearance of conductors from surface of pole shall not be less than as specified in Rule 54.4-D6b.
See Rule 54.7-A1 and Rule 54.11-F for climbing space requirements for conductors dead ended on poles in vertical configuration.
