What working space is required around a panelboard?

• A. A 2-foot clearance all around the panel.
• B. 4 feet in front and 24 inches on sides.
• C. A 3-foot path in front with 30-inch width on the sides.
• D. No specific space required if accessible.

Answer: (C)

Working space around panelboards is about safe access and the ability to work on or operate the equipment without crowding live parts. The standard requires a front clearance of three feet, giving you enough room to stand, move, and use tools safely. It also requires at least thirty inches of clear width to the sides, so you have room to reach breakers and route conductors without hitting energized parts. That combination—three feet in front with thirty inches of clear width on the sides—provides the minimum safe workspace. A two-foot front clearance is too small, while a four-foot front with only twenty-four inches on the sides doesn’t meet the side-width requirement. There is a specific space requirement for safety, not none.
