What is the required space depth for Condition 3 equipment operating at a maximum of 600 volts?

• A. Arc-flash hazard
• B. Minimum depth of working space
• C. Enclosure-type number mark
• D. Accidental contact prevention

Answer: (B)

Safe access around electrical equipment requires a defined amount of room to work comfortably and safely. The space depth refers to the distance you must have in front of the equipment to reach, operate, and service it while keeping a safe separation from live parts. For Condition 3 equipment with a maximum voltage of 600 volts, the standard calls for the minimum depth of working space. This ensures there’s enough room to perform tasks, maintain proper posture, and apply insulation and tools without encroaching on energized parts. The other options describe different safety considerations (arc-flash risk, labeling, or physical barriers) but do not specify the required working-space depth.
