What should be the clearance requirement around electrical panels?

The requirement for at least 30 inches of clearance in front of electrical panels is crucial for ensuring safe access to the panel for operation and maintenance. This space allows individuals to open the panel door fully without obstruction and to work on the panel safely. It helps prevent accidents and injuries during electrical maintenance tasks, providing ample room for tools and ensuring that anyone accessing the panel can do so without the risk of working in a cramped or hazardous environment.

The other options do not align with standard electrical safety requirements. While clearance may also be required on the sides and above the panel, the front clearance is essential. Additionally, the notion that no clearance is necessary as long as the panel is closed would compromise safety standards, as accessibility for emergency situations or routine inspections must always be considered.
