According to the NEC, how much clearance depth is required in front of a panel from floor to ceiling?

24 inches
30 inches
36 inches
48 inches

The correct answer is: 36 inches

The National Electrical Code (NEC) specifies that there should be a minimum clearance in front of an electrical panel to ensure safe operation and maintenance. The correct answer is based on NEC 110.26(A)(1), which outlines that a minimum of 36 inches of clear working space is required in front of electrical equipment. This clearance depth is crucial for safe access, allowing electricians or maintenance personnel to work on the panel without obstruction. In practice, maintaining this 36-inch clearance helps prevent accidents and injuries by ensuring that workers can operate tools and access controls effectively. It also allows for safe operation of the equipment and reduces risks associated with electrical hazards. The other options do not meet the NEC's requirements for clearance in front of electrical panels, making them inadequate for safety and compliance with regulations.
