The minimum horizontal climbing space required between power conductors and communication conductors supported on poles is 30 inches. This regulation is in place to ensure the safety of workers and to provide adequate space for maintenance and repairs. The 30-inch separation helps to minimize the risk of accidental contact between the two sets of conductors during climbing and working on poles.

This specific measurement is based on the National Electrical Safety Code (NESC), which sets standards for electrical installations to promote safety. Having the correct horizontal distance helps to maintain safe working conditions and avoids potential hazards that could arise from the proximity of power lines to communication lines, such as electrical arcing or increased risk of electrical shock.

Other options, while they might suggest larger separations, do not reflect the current standards set forth by the NESC for the specific context of climbing space between these different types of conductors.
