A personnel access opening to an enclosure must not be located directly above electrical equipment or conductors. Which option best reinforces this rule?

• A. True
• B. False
• C. Only for round openings
• D. Only when the enclosure is energized

Answer: (A)

Openings should not be located directly above electrical equipment or conductors because there is a real risk of injury or damage if something drops or if a person’s hand or a tool enters from above where energized parts are exposed. Placing the access opening to the side or front helps keep the path of entering the enclosure away from live components, reducing the chance of accidental contact, arcing, or electric shock. This rule is a general safety practice for reducing exposure during maintenance, not something that depends on the shape of the opening or whether the enclosure is energized. Therefore, the statement is true.
