What is the minimum front clearance required around electrical equipment rated at 600 volts or less?

• A. 2 feet
• B. 3 feet
• C. 4 feet
• D. 6 feet

Answer: (B)

In electrical safety, you must have enough space in front of equipment to reach controls, operate disconnects, and work without brushing energized parts. For equipment rated at 600 volts or less, the minimum front clearance is three feet. That three-foot buffer allows a worker to stand, open doors or panels, and use tools safely while keeping a safe distance from live parts and potential arc flash. It also accommodates the normal swing of panels and the space needed to move around the gear during maintenance or testing. While some situations or higher voltages require larger clearances, three feet is the standard minimum for 600V or lower.
