How often should electrical panels be inspected?

NFPA 70B recommends electrical panel inspections every 1-3 years depending on facility type, with annual inspections for industrial environments and high-humidity or corrosive locations. NEC requires inspection after installation and major modifications. Annual thermographic (infrared) scanning of panels is best practice to identify hot spots before failures occur. Circuit breakers should be exercised (opened and closed) annually to prevent corrosion of contacts.

What are the clearance requirements for electrical panels?

NEC 110.26 requires a minimum 3-foot (36-inch) clear working space in front of electrical panels rated up to 150V to ground, and 3.5-4 feet for higher voltages. The workspace must be 30 inches wide and extend from floor to ceiling. OSHA 1910.303 mirrors NEC clearance requirements for general industry. Panels must be accessible and cannot be blocked by shelving, equipment, or stored materials. Violations are among the most common OSHA electrical citations.
