What is a potential risk of having PPGs placed farther from the work location?

Having potential ground points (PPGs) placed farther from the work location introduces the risk of increased resistance. This is primarily due to the longer distance the electrical current must travel to reach the ground, which can affect the overall grounding system's effectiveness.

When grounding electrodes are spaced out and far from where work is being performed, the electrical connection may not be as robust. This can lead to a higher resistance pathway for fault currents, which in turn diminishes safety and can lead to a risk of electrical shock or equipment failure. Effective grounding ensures that any fault currents are adequately dissipated, reducing the risk of hazards.

The importance of keeping PPGs strategically placed closer to the work area is to minimize resistance and ensure better protection against electrical faults. This factor is critical for maintaining safety standards and abiding by best practices in lineman work.
