Checking ground rod resistance
WebOct 28, 2024 · The purpose of a ground test well is two-fold: to be able to quickly and easily measure resistance-to-ground of the grounding electrode and/or to measure point-to-point continuity (resistance) from one electrode to another. WebMar 3, 2024 · The most common and widely accepted method is the 3-Pole Fall-of-Potential method. First, disconnect the grounding electrode conductor from the ground rod. Second, connect the tester to the exposed top of the ground rod. Then, place the two earth stakes in the soil in direct line away from the ground rod, up to 65 feet.
