What is the minimum width required for the wall space that hosts an electrical panel?

The minimum width required for the wall space that hosts an electrical panel is 30 inches. This space must be maintained clear to ensure safe access to the panel for operation, maintenance, and emergencies. The National Electrical Code (NEC) emphasizes safety by establishing these clear working spaces to provide adequate room for individuals to work without obstruction.

Compliance with this clearance not only enhances safety but also allows for proper ventilation and reduces the risk of accidental contact with energized components within the panel. By adhering to the requirement of 30 inches in width, installers and maintenance personnel can easily access the panel while minimizing risks associated with electricity.
