Rule 54.11-F

54.11-F.    Climbing Space

(1)    One Vertical Circuit at Pole Top: For a single circuit at the top of the pole, the climbing space shall be maintained to the lowest conductor on the climbing side of the pole and workmen shall not go above the lowest conductor level,

EXCEPT:

a)    When Conductors Are Moved Out From Pole by accepted "hotline" techniques, or

b)    When the Pole Top Circuit Is De-energized and grounded, the climbing space shall be maintained to the top conductor of the circuit and the climbing space shall not be less than 30 inches square.

(2)    Two Vertical Circuits at Pole Top: When two vertical circuits are installed at the top of pole, the climbing space shall be maintained to the lowest conductor level of those circuits on the climbing side of the pole and workmen shall not go above such lowest conductor level,

EXCEPT:

a)    When Conductors Are Moved Out From Pole by accepted "hotline" techniques, or

b)    When Both Circuits Are De-energized and grounded the climbing space shall be maintained to the top conductors of the circuits. The space shall not be less than 30 inches square.

c)    When One Circuit Is De-energized and grounded, the climbing space shall be maintained on the climbing side between the center line of the pole and the de-energized conductors. The space shall be not less than 36 inches square.

(3)    Vertical Circuits Bonded Together: When vertical circuits are bonded together, regardless of location on the pole, the climbing space shall be maintained to the lowest conductor level of those circuits on the climbing side of the pole and workmen shall not go above such lowest conductor level, unless conductors are moved out from pole by accepted "hotline" techniques, or

EXCEPT:

a)    Where a Single Circuit is Involved and such circuit is de-energized and the bond and the de-energized circuit is grounded as required in Rule 53.4-A3b, the climbing space shall not be less than 36 inches and shall be maintained for a vertical distance of not less than 4 feet below the lowest conductor and not less than 4 feet above the top conductor when not at the top of pole.

b)    Where Two Circuits Are Involved:

1)    When Both Circuits Are De-energized and commonly bonded and the bond and the circuits grounded as required in Rule 53.4-A3b, the climbing space shall be maintained to the top conductors of the circuits. The space shall not be less than 36 inches square and shall be maintained for a vertical distance of not less than 4 feet below the lowest conductor and not less than 4 feet above the top conductor when not at the top of pole.

2)    When One Circuit Is De-energized and both circuits are commonly bonded and the bond and the de-energized circuit grounded as required in Rule 53.4-A3b, the climbing space shall be maintained on the climbing side between the center line of the pole and the de-energized conductors. The space shall not be less than 36 inches square, and shall be maintained for a vertical distance of not less than 4 feet below the lowest conductor and not less than 4 feet above the top conductor when not at the top of pole.

(4)    Unbonded Circuits Below Pole Top: For unbonded circuits below the pole top position climbing space shall be maintained through the levels of conductors supported on post insulators for a vertical distance of not less than four feet above the top conductor and not less than four feet below the lowest conductor.

The climbing space shall be a square of horizontal dimensions tabulated below and one side of the climbing space shall pass through the center line of the pole.
