How should a panel enclosure be kept accessible during inspection?

• A. In a locked cabinet with the door kept closed.
• B. Be placed in a closet behind a door.
• C. With adequate clearance and unobstructed space around the panel for safe operation and testing.
• D. Hidden behind drywall.

Answer: (C)

Keeping the panel readily accessible with unobstructed space in front is essential because inspectors must be able to reach, open the enclosure, read labeling, and operate or test the circuits safely. Electrical code requires a clear working space in front of equipment—typically at least 3 feet deep and wide enough for the panel—so there’s room to work without moving obstacles. Options that lock the cabinet, place the panel behind a door, or hide it behind drywall block access and prevent safe inspection and servicing. So, maintaining adequate clearance and an open, unobstructed area around the panel best supports safe operation and proper inspection.
