What minimum working space is required in front of electrical equipment such as panels?

• A. 1 foot (0.3 m) of clear space
• B. 2 feet (0.6 m) of clear space
• C. 4 feet (1.2 m) of clear space
• D. 3 feet (0.9 m) of clear space

Answer: (D)

Three feet of clear space in front of electrical equipment keeps the area open for safe access and operation. This much room lets you stand, reach the controls, and open doors or panels without brushing against live parts or feeling cramped. It also provides space to use tools and work comfortably without obstruction, reducing the risk of accidental contact with energized components. Shorter spaces (one or two feet) would crowd the front of the equipment and hinder safe operation, while four feet is more than the minimum required.
