What is the minimum headroom required above service equipment, switchboards, panel boards, or motor control centers?

The minimum headroom required above service equipment, switchboards, panel boards, or motor control centers is 6.5 feet. This requirement is established to ensure safe access to electrical equipment for operation, maintenance, and inspection. Adequate headroom is crucial because it allows technicians and electricians to work comfortably without the risk of bumping their heads on overhead structures. This standard seeks to promote safety in the workplace by minimizing hazards associated with low ceilings above electrical apparatus. Maintaining this minimum headroom also contributes to compliance with electrical codes and regulations, which mandate clearances for proper functioning and accessibility of electrical systems.
