What is the minimum width of working space required around an electrical panel?

The minimum width of working space required around an electrical panel is 30 inches. This requirement ensures that there is adequate room for technicians to safely and effectively perform maintenance, inspections, and any necessary repairs on the panel without the risk of injury or obstruction. The 30-inch space is measured from the center of the equipment and allows for safe maneuvering and access to the panel controls and wiring, which is crucial for maintaining safety standards in electrical work. This guideline is established by national electrical codes to prioritize safety and accessibility in the management of electrical systems.
