In a workspace where exposed live parts are present on both sides, what is the minimum working space required?

In a workspace where exposed live parts are present on both sides, the National Electrical Code (NEC) specifies that a minimum working space of 4 feet is required. This distance is established to ensure safety for individuals who may need to perform maintenance or repairs in close proximity to live electrical components.

The 4-foot requirement provides sufficient space to safely maneuver tools and maintain a safe distance from the electrical hazards that exist on both sides. It also allows for appropriate access and visibility, which is essential when working in such conditions, reducing the risk of accidental contact with live parts. This minimum spacing standard aligns with safety practices and regulations intended to protect workers in environments where electrical dangers are present.
