What is the required working space for access to live parts operating at 300V to ground with exposed live parts on one side?

2 feet
3 feet
3 and 1/2 feet
4 feet

The correct answer is: 3 and 1/2 feet

The required working space for access to live parts operating at 300V to ground with exposed live parts on one side is 3 and 1/2 feet. This requirement is based on safety standards that aim to protect electrical workers from the risks associated with working near energized components. The distance of 3 and 1/2 feet provides a safe working zone that takes into account potential hazards such as electric shock or arc flash. By establishing a clear zone, it helps ensure that personnel can safely perform their tasks while minimizing the risk of accidental contact with live components. Compliance with these space requirements is critical for maintaining safety in electrical installations and operations. While other distances may have been considered, they do not meet the specific criteria outlined for this voltage level and scenario where live parts are exposed on one side. Thus, the 3 and 1/2 feet distance is specifically mandated to enhance safety standards in the electrical field.
