What is the minimum distance a service conductor near windows or doors must maintain?

Explanation:
The essential idea is to keep service conductors a safe distance away from any openings in a building so people can’t accidentally contact them or have an arc reach through a window or door. The minimum distance required in this situation is three feet. This gives enough room for people to operate doors or windows and for tools, ladders, or other objects to stay clear of the energized conductors. Shorter distances, like one foot, are unsafe because they increase the chance of contact; larger distances such as five or eight feet are more than the minimum the code requires in this scenario.
