General Order 95
Requirements for All Lines
34 Foreign Attachments
Nothing in these rules shall be construed as permitting the unauthorized
attachment, to supply, street light or communication poles or structures,
of antennas, signs, posters, banners, decorations, wires, lighting fixtures,
guys, ropes and any other such equipment foreign to the purposes of overhead
electric line construction.
Nothing herein contained shall be construed as requiring utilities
to grant permission for such use of their overhead facilities; or permitting
any use of joint poles or facilities for such permanent or temporary construction
without the consent of all parties having any ownership whatever in the
poles or structures to which attachments may be made; or granting authority
for the use of any poles, structures or facilities without the owner’s or
All permanent attachments must be approved by the Commission
(see Rule 15.1
) and the owner(s) involved.
All temporary attachments shall be restricted to installations
where the period is estimated to be one year or less.
The utilities, or other governmental entities may require
construction standards which are more restrictive than the requirements
of this Rule 34
The following rules shall apply to approved temporary
foreign attachments installed on climbable poles and structures and shall
be maintained as required by Rule 12.2
(1) Messengers and Span Wires: Messengers and Span Wires (when
used under the definitions of Rules 22.3
respectively) may be used as supports when the following requirements are
a) Material and Size Requirements: See
Messengers and Span Wires.
b) Sectionalizing Requirements: Insulators shall be installed in all
messengers and span wires, when used within the scope of this rule, and shall
be located at a distance of not less than 6 feet and not more than 9 feet,
measured along the messenger or span wire, from the points of attachment to
the poles or structures. Sectionalizing insulators shall meet the requirements
of Rules 56.8
c) Attachments: Messengers and span wires shall be attached to poles
with through bolts and shall be protected by the use of guy thimbles or their
equivalent where attached to the through bolts. Steel pole bands or their
equivalent shall be used for steel and concrete poles.
In no case shall any apparatus (decorations, banner, wire, cable, lights, etc.) be supported by the utilities’ or licensees’ conductors, cables, messengers, span wires or guys.
(2) Rope: Rope may be used as a support for banners and decorations
for short periods of time (to be determined by the granting authority) when
the following conditions are met:
a) Only non–energized banners and decorations shall be supported with rope.
b) The rope must be securely tied to the pole or structure with all
excess rope removed and must not contact or obstruct any pole steps.
c) The rope must supply a safe minimum working load strength of 200
pounds, which is equivalent to 3/8 inch manila rope.
(3) Apparatus Supported on Brackets Attached to Poles: All attachments
supported on brackets with a supply voltage of 0 - 750 volts shall meet
the requirements of Rules 58.5–B
B. Climbing Space
All apparatus shall be installed outside of climbing space.
When temporary pole bands or ropes are used to support attachments,
the bands or ropes shall be limited to 6 inches in width with no more than
one band or width of rope allowed in any 24 inch section of climbing space.

(1) Messengers and Span Wires:
a) Messengers: Messengers supporting energized apparatus, insulated
wires or cables, etc. shall meet the clearance requirements of
b) Span Wires: Span wires supporting non–energized equipment (banners,
decorations, etc.) shall meet the clearance requirements of
(2) Energized Apparatus: All energized apparatus (decorations, wire,
cable, lights, etc.) shall maintain the same clearances from conductors
as those required for
0 - 750 volt service drops (
Table 2, Column D
, and Rule 54.8
(3) Non–Energized Apparatus, Vertical and Radial Clearances:
a) A minimum vertical clearance of 6 feet below any energized conductor
level shall be maintained to any part of attachments supporting non–energized
b) A minimum radial clearance of 1 foot shall be maintained from any
street light and its supporting fixtures.
c) A minimum radial clearance of 1 foot shall be maintained from all
communication cables and messengers.
(4) Miscellaneous Equipment: A minimum radial clearance of 1 foot shall
be maintained from any supply or communication device (power supply cabinets,
communication drop distribution terminals, switch enclosures, operating
equipment, etc.) where access may be required by workers. To ensure access
and operation a greater clearance may be required by the utility or licensee
D. Vertical Clearance Requirements above Thoroughfares, Ground, etc.
Vertical clearance requirements as in Rule 37 , Table 1, Column B, Cases 1 to 5 inclusive, shall be maintained.
E. Vertical and Lateral Runs
For the requirements of vertical and lateral runs of conductors see Rule 54.6 .
Energized Conductor (Wire or Cable)
All energized conductor (wire or cable) shall be covered with an insulation suitable for the voltage involved (See Rule 20.9–G ).
Where mechanical loads imposed on poles or structures exceed safety factors as specified in Rule 44, or at the request of the granting authority, additional strength shall be provided by the use of guys or other suitable construction. When guying is required, refer to Rules 56 and 86 for applicable requirements.
