The distance must be calculated in some cases due to transient voltage variation between utilities. Best to contact the utility or use the OSHA Is there a chart for the minimum distance that an energized conductor can be moved toward a grounded object?
The insulators are only 3 ft 6in and the conductor can be moved creating foe space for MAD put the distance to the pole or tower is shorter than MAD. I have always never moved anything closer than the MAD to any difference in potential and with the changes wonder what is the proper way to handle it.

Additionally, contact between live power lines and metal objects e. OSHA says the newly revised rule will save approximately 20 lives and prevent serious injuries per year. David Michaels, assistant secretary of labor for occupational safety and health. This harmonization is necessary to ensure the same rules apply to the same kinds of work, OSHA stated. Additionally, the rule features new or revised requirements for fall protection, minimum approach distances, arc-flash protection, and electrical protective equipment for both construction and general industry.
