About this detail

Pad-mounted electrical equipment requires a minimum ten-foot clear area in front of access doors to allow the use of hot sticks and safe working practices. Non-access sides require a three-foot clear area, while equipment must be spaced eight feet from combustible structures and three feet from non-combustible structures with no openings closer than ten feet. Solid windows or air vents require ten feet of separation, and operable doorways or air intakes require twenty feet. Clear zones must remain free of vegetation and trip hazards.
