Change List for this Rule


Original Version
Rule 54.6-A


54.6-A.    Unprotected Conductors (see Rule 20.8-D for definition)

 

Unprotected conductors from one level on a pole or structure to another level 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 the 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 before conductors

0-5000 volts

 11 ½ inches

5000-7500 volts

 17 ½ inches

7500-20,000 volts

 24 inches

20,000 volts and above

 36 inches

 

Where the distance between levels is in excess of 12 feet and unprotected conductors pass between the pole-pin conductor positions of any other 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 buckram 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 58.2-B3 and 92.1-F5
