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 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 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.
