54.7-A.    Climbing Space

Climbing space, measured from centerline of pole, shall be provided on one side or in one quadrant of all poles or structures, with dimensions as specified in Rules 54.7-A1, 54.7-A2 and 54.7-A3.

The climbing space shall be maintained in the same position for a distance of not less than 4 feet vertically both above and below each conductor level through which it passes. Compliance with this requirement necessitates that the position of the climbing space shall not be changed through conductor levels which are less than 4 feet apart.  Where the vertical distance between consecutive conductor levels is 4 feet or more, and less than 8 feet the position of the climbing space through such consecutive levels may be shifted not more than one-quarter of the distance around the pole.  Where a conductor is installed at the top of a pole under the provisions of Rule 54.4-D8, the climbing space shall extend up to the level of such pole-top conductor but need not be provided through and above such level.

Allowable obstruction of these climbing spaces, where necessary, are specified in Rule 54.7-A4

This Rule 54.7-A need not apply to non-climbable metal poles in partial underground distribution, provided the regular written operating rules of the utility concerned specify that all work on conductors and equipment supported by such poles shall be performed only from aerial lifts and (1) in the case of primary conductors, shall be done with live-line tools after installing adequate insulating and protective devices or barriers in order to (a) prevent accidental contact by the workman with the energized conductors other than the conductor being worked on and (b) to minimize the possibility of simultaneous contact of the metal parts of live-line tools with the grounded pole and the energized conductor and (2) in the case of secondary conductors shall be done after suitably covering all energized primary conductors with adequate insulating and protective devices or barriers.
