When normally enclosed live parts are exposed for inspection, how should the working space be managed?

When normally enclosed live parts are exposed for inspection, the primary focus should be on safety and preventing unauthorized access to dangerous areas. Guarding the working space ensures that individuals who are not trained or authorized to be in close proximity to live electrical components are kept at a safe distance. This protects personnel from electrical shock hazards and reduces the risk of accidental contact with live parts during the inspection.

While marking the area, having personnel watch, or restricting access might contribute to overall safety practices, these measures alone do not provide the physical barrier required to effectively guard exposed live parts. Guarding the area creates a clear boundary that defined access, which is essential when working with potentially dangerous electrical equipment. Doing so is in line with NEC standards designed to ensure safety in electrical installations and maintenance work.
