For large electrical equipment such as switchgear and control panels that are at least 6 feet wide, which feature is required?

• A. An entrance at each end
• B. A ventilation opening
• C. A locking pin
• D. A dedicated lighting circuit

Answer: (A)

Access and egress around large electrical equipment is the focus. When switchgear and control panels are very wide (at least six feet), there must be an entrance at each end to ensure safe, unobstructed access from either side. This dual-entry setup allows personnel to reach and work on the equipment from both directions and provides a clear, back-up route in case one side is blocked or crowded, which is important for safe maintenance and emergency egress. Ventilation openings, locking pins, or a dedicated lighting circuit may be useful in other contexts, but they aren’t the specific requirement linked to the equipment’s width. The need for entrances at both ends directly addresses safe access and egress for large enclosures.
