When is it advisable to conduct baseline three-point tests for a newly installed grounding system?

• A. Every month for the first year
• B. Every season for the first year
• C. Every week for the first month
• D. Every year after installation

Answer: (B)

Conducting baseline three-point tests for a newly installed grounding system every season for the first year is advisable because it allows for regular monitoring of the system's performance during different weather conditions and soil moisture levels. Seasonal testing can help identify any changes in the grounding system's effectiveness over time, especially due to environmental factors that could impact resistivity and overall performance. By testing every season, practitioners can ensure that the grounding system maintains its integrity and performs as expected. This practice also aligns with industry standards, which often recommend regular assessments during the critical first year post-installation, a period when the performance may be influenced by settling soil and other factors. Maintaining this frequency during the initial year helps address any potential issues early on before they can lead to significant problems. Less frequent testing, such as annually or monthly, may not provide sufficient data for understanding seasonal variability and how it affects the grounding system's effectiveness.
