What is considered the preferred method of grounding for electric work?

Equipotential grounding is recognized as the preferred method of grounding for electrical work because it ensures that all conductive parts of an electrical system are at the same electrical potential. This uniformity is crucial in minimizing the risk of electrical shock or equipment damage. By bringing different parts of the system to a common ground level, it helps protect workers and equipment from voltage differentials that can occur during fault conditions.

The use of equipotential grounding creates a safety zone around work areas, which can significantly improve the safety of linemen and technicians while they handle electrical equipment. It effectively reduces the possibility of ground-loop currents that may arise from differing ground potentials, thereby protecting both personnel and equipment from unexpected surges or faults.

This method is typically achieved using grounding conductors that connect various parts of the system to a common ground, which can include poles, equipment, and structures. The goal is to create a scenario where everyone working on or near the equipment has the same ground reference, enhancing overall electrical safety.
