Rule 54.11-F

54.11-F.    Climbing Space

(1)    Where Insulators Are in vertical or Horizontal Climbing Position, more than 750 volts: Climbing space shall be maintained through the levels of conductors for a vertical distance of not less than 4 feet above the top conductor and not less than 4 feet below the lowest conductor.

EXCEPTION:    For a circuit at the top of the pole, the climbing space shall be maintained to the lowest conductor of the circuit on the climbing side of the pole (See Figure 54-5.).

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.

(2)    Dimensions Where Conductors Are Dead-ended In vertical Configuration: Climbing space through conductors shall be a square of the horizontal dimensions tabulated below, and shall be located either on one side or a quadrant of the pole (See Figure 54-6.).
