What is the minimum size of personal protective grounds required?

The minimum size of personal protective grounds specified as #2 AWG copper is based on established safety standards that ensure adequate current-carrying capacity and low resistance to minimize the risk of electric shock when working near energized equipment. The size of the grounding conductor is crucial for effectively dissipating fault currents into the ground, which is vital for protecting both personnel and equipment.

Using #2 AWG copper provides a balance between flexibility, conductivity, and robustness, making it effective in applications where grounding is necessary to ensure safety. This size is widely recognized in industry standards, emphasizing its reliability for personal protective grounding techniques.

Other sizes, such as 1 AWG copper or 4 AWG aluminum, may not meet the same level of safety or performance in certain scenarios, as they could either be insufficient in handling fault currents or not provide the necessary conductivity compared to #2 AWG copper.
