Is it safer to ground using an equipotential zone compared to performing live-line work on a circuit?

Grounding using an equipotential zone is indeed considered safer than performing live-line work on a circuit. The primary reason for this is that an equipotential zone is designed to minimize the potential difference between any points within that area, essentially reducing the risk of electric shock to individuals. When workers are in an equipotential zone, they can effectively eliminate the risk associated with stepping voltage – a condition that can occur when there are differences in voltage levels across a distance.

In contrast, live-line work requires workers to perform tasks while the circuit is energized, exposing them to the inherent hazards of electrical energy. Even with proper personal protective equipment (PPE) and specialized tools, live-line work still carries risks, such as accidental contact with conductive materials or unforeseen changes in the circuit.

Thus, grounding in an equipotential zone not only enhances safety by distributing voltage evenly across a defined area, but it also reduces the risk of electric shock, making it a safer alternative to live-line work where many more variables can complicate safety.
