Original Version

Rule 54.6-A

 

54.6-A    Unprotected Conductors (See Rule 20.8-E for definition)

 

Unprotected conductors may pass laterally on a pole or structure or vertically from one level on a pole or structure to another level, but shall not pass within the climbing space; shall not pass within the working space, except as permitted by Rule 54.7-B2; shall not pass between conductors of any other circuit, except between pole-pin conductor positions; and shall clear the conductors of other circuits by distances not less than the following:

 

Highest Voltage Classification of Conductors Concerned

Minimum Radial Distance between Conductors

0 - 5,000 Volts

11.5 inches

5,000 - 7,500 Volts

17.5 inches

7,500 - 20,000 Volts

24 inches

20,000 Volts and above

36 inches

 

Where unprotected vertical conductors are in excess of 12 feet in length, additional supports shall be installed so that the maximum length of conductor between supports is not more than 12 feet.

 

The clearances in the above tabulation do not apply between taps in buckarm construction, the clearances specified in Table 2, Case 16, being directly applicable.

 

For clearances between street light drop wires and cables, other conductors and metal boxes, see Rules 58.5-B3 and 92.1-F5.

 

Unprotected conductors, installed as specified in this rule (54.6-A) and in Rule 54.4-D9 are not vertical or lateral runs as defined in Rule 22.6.

 

In lieu of the foregoing, vertical and lateral conductors may be installed as specified in Rules 54.6-C and 54.6-D.

EXCEPTION:    The minimum radial distances in this rule shall not apply to uncovered, grounded, non-dielectric fiber optic cables in transition on metallic structures, which must comply with Rule 38, Table 2, Case 16a.

 

Where unprotected vertical conductors are in excess of 12 feet in length, additional supports shall be installed so that the maximum length of conductor between supports is not more than 12 feet.

 

The clearances in the above tabulation do not apply between taps in buckarm construction, the clearances specified in Table 2, Case 16, being directly applicable.

 

For clearances between street light drop wires and cables, other conductors and metal boxes, see Rules 58.5-B3 and 92.1-F5.

 

Unprotected conductors, installed as specified in this rule (54.6-A) and in Rule 54.4-D9 are not vertical or lateral runs as defined in Rule 22.6.

 

In lieu of the foregoing, vertical and lateral conductors may be installed as specified in Rules 54.6-C and 54.6-D.

EXCEPTION:    The minimum radial distances in this rule shall not apply to uncovered, grounded, non-dielectric fiber optic cables in transition on metallic structures, which must comply with Rule 38, Table 2, Case 16a.

 

Where unprotected vertical conductors are in excess of 12 feet in length and unprotected conductors pass between the pole pin conductor positions of any circuit additional supports shall be installed so that the maximum length of conductor between supports is not more than 12 feet.

 

The clearances in the above tabulations do not apply between taps in buckarm construction, the clearances specified in Table 2, Case 16 being directly applicable.

For clearances between street light drop wires and cables, other conductors and metal boxes, See
Rules 58.5-B3 and 92.1-F5

 

Unprotected conductors, installed as specified in this rule (54.6-A.) and in Rule 54.4-D9 are not vertical or lateral runs as defined in Rule 22.6.

 

In lieu of the foregoing, vertical and lateral conductors may be installed as specified in Rules 54.6-C and 54.6-D.
