True or False: Soil conditions do not affect grounding resistance.

Soil conditions play a significant role in grounding resistance, making the statement false. Grounding systems rely on the earth as a reference point, and the electrical resistance between the grounding electrode and the earth can vary considerably based on soil moisture, composition, temperature, and other factors.

For instance, moist soil typically has a lower resistance than dry soil, which enhances the effectiveness of grounding systems. Conversely, rocky or sandy soils can have higher resistivity, increasing grounding resistance and potentially leading to inadequate grounding performance. Grounding systems must be designed to account for these variances to ensure safety and functionality, which is why the conditions of the soil directly influence grounding resistance.
