Original Version
Rule 54.4-C4b


54.4-C4b)    Conductors of More than 750 Volts: Where conductors of more than 750 Volts are supported in vertical configuration directly on a 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 pin spacings specified in Table 2, Case 15;

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 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; 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 for climbing space requirements for conductors dead ended on poles in vertical configuration.
