Ground resistance testing interval

Ground resistance testing interval

Ground resistance testing interval

(OP)
If the grounding system at a building is acceptable now how often should the ground resistance be tested to ensure continued performance? I am concerned about the integrity of the buried grounding electrodes.

RE: Ground resistance testing interval

Every 2 years per NETA MTS

RE: Ground resistance testing interval

Yup 2 years is a standard in most countries in world. But you should check with the state regulations (It can be more than 2 years).
