What is the minimum height requirement for working spaces in electrical equipment?

The minimum height requirement for working spaces in electrical equipment is 6.5 feet. This height is established to ensure safe access and working conditions around electrical installations, allowing electricians and maintenance personnel adequate space to perform their tasks without risk of injury or interference with the equipment. Providing a working space that is at least 6.5 feet high enables individuals to stand upright while working, which is crucial for both safety and efficiency when accessing electrical panels, switchboards, and other equipment. This requirement is outlined in the National Electrical Code to promote safety and operational standards in electrical installations.
