The minimum clearance required between side wall and the Main Switchboard is

In most electrical standards, it is recommended to maintain a minimum clearance of around 3 feet (1 meter) between the side wall and the Main Switchboard. This distance ensures sufficient space for safe operation, maintenance, and emergency access without obstructing the vital electrical components, allowing technicians to work efficiently and safely. When installing a Main Switchboard, remember that local codes and regulations can vary. It's always a good idea to consult the National Electrical Code (NEC) or the local building authority to confirm specific clearance requirements. Ensuring compliance helps avoid any potential hazards and ensures a safe environment when accessing the switchboard.
