Theory & Safety第 117 / 120 题
What is the minimum width of working space in front of electrical equipment?
a.30 inches in all cases regardless of equipment width
b.30 inches, or the width of the equipment, whichever is greater
c.36 inches, or the width of the equipment, whichever is greater
d.24 inches, measured from the centerline of the equipment
解析
The working space must be at least 30 inches wide or as wide as the equipment, whichever is greater, and it must allow all doors and hinged panels to open at least 90 degrees. The space need not be directly centered on the equipment, but it must be continuous across the full width required.
