What is the minimum working space required in front of an electrical panel?

The minimum working space required in front of an electrical panel is established to ensure safety and accessibility for maintenance and operation. The National Electrical Code (NEC) sets specific guidelines to facilitate safe working conditions for electricians and technicians.

The correct minimum requirement states that there should be a working space that is at least 30 inches wide and 36 inches deep in front of the electrical panel. This space allows enough room for personnel to safely and effectively access the panel for operation, maintenance, or emergency responses. The width is necessary to accommodate the technician working in front of the panel, and the depth is crucial to ensure they can reach the panel without being constrained or in a precarious position.

In the context of the available choices, this configuration specifically meets the NEC standards, providing both safety and adequate space for necessary tasks.
