WebOct 28, 2024 · One of the most common ways ground test wells are improperly-installed, as seen in the image on the left. In this scenario, the installer has simply provided physical access to the ground ring with a ground rod “T-welded” into the loop. This scenario allows us to clamp on to the ground loop conductor above the ground rod itself.
