What is the main reason for establishing an equipotential zone at a worksite?

Establishing an equipotential zone at a worksite is primarily aimed at creating a uniform electrical potential across a designated area. This is crucial to minimize the risk of electric shock to workers who may be in close proximity to energized equipment. By ensuring that the potential difference between any two points within the zone is minimized, the zone effectively allows currents to flow safely across the workers' body without creating a dangerous situation.

The purpose of bypassing a significant amount of current around the worker is essential in preventing inadvertent electrical pathways through which current could flow, potentially leading to injury. This practice protects individuals by ensuring that any electrical fault does not create hazardous exposure to differences in voltage, thus significantly enhancing safety in environments where electrical work is performed.

Establishing an equipotential zone also involves grounding techniques that help manage and control electrical risks, ensuring that all conductive parts are at the same potential. This is critical in mitigating the dangers associated with accidental contact with energized equipment or surfaces that may become live due to fault conditions. Therefore, the main reason for establishing an equipotential zone is to ensure safety and protect workers from electrical hazards.
