An equipotential zone is created by which of the following methods?

An equipotential zone is crucial for ensuring the safety of workers in environments where electrical hazards exist. By placing a low-resistance shunt in parallel with the worker, a path for electrical current is provided that minimizes potential differences that could lead to electric shock. This effectively balances electrical potentials around the worker and helps to ensure that the electrical potential in the area remains at the same level, preventing any harmful voltage differences.

Creating an equipotential zone is essential for reducing the risk of injury, as it allows the worker to maintain a consistent electrical potential with the surrounding objects, including equipment and structures. This method enhances safety by ensuring that any stray voltage is safely redirected, thereby protecting the worker from dangerous currents.

In contrast, high-resistance shunts would not effectively create an equipotential zone since their purpose is to limit current flow rather than allow balanced potentials. Installing multiple ground rods could help in grounding and may support an overall grounding system, but it does not specifically address the creation of an equipotential zone around a worker. Using only isolated equipment does not mitigate potential differences, since isolation may lead to various parts of the worker's environment being at different potentials, thus creating a risk rather than alleviating it.
