What is the required distance for unqualified workers to stay away from distribution circuits?

Unqualified workers must maintain a distance of 10 feet (3 meters) from distribution circuits to ensure their safety. This distance is established based on industry standards designed to prevent electrical hazards. The reasoning for this distance takes into account the potential for accidental contact, the risk of arc flash incidents, and the need to minimize the exposure to live electrical parts that could cause serious injuries or fatalities.

Maintaining a clearance of 10 feet helps to protect individuals who are not trained to work around electrical systems by providing a safe space where they are less likely to be affected by electrical faults or equipment failure. This guideline reflects the understanding that even a small electrical contact can be dangerous and that increasing the distance reduces the risk of one inadvertently entering into a hazardous area.
