What defines the working space around electrical panels?

• A. A clear, unobstructed area in front of panels to allow safe operation and servicing.
• B. A space used for storing tools.
• C. A space only for doors to swing open.
• D. A space required for emergency egress.

Answer: (A)

The working space is the clear, unobstructed area in front of electrical panels that lets you safely operate and service the equipment. This space is required so a person can reach, inspect, test, and work on the panel without crowding or hitting the panel or conductors. It must be kept free of stored items and other obstructions, and its size is defined by code: at least 3 feet of depth in front of the panel, and a width not less than the equipment width (and no less than 30 inches), with a vertical clearance of about 6.5 feet or the height of the equipment. In short, this choice describes the actual, safe working space needed for panels, rather than storage, door swing, or egress considerations.
