I’m trying to work through my educational requirements here on NACHI and am looking for some clarification on connecting grounding systems to the ground.
The following is from the training:
There are several methods of connecting the grounding system to the ground, with a driven rod being the most common in most areas. Most residential construction requires two separate grounding electrodes in any combination of the following (which need to be at least 6 feet apart):
- driven rods;
- metal water pipes;
- well casings;
- Ufer grounds;
- ground plates;
- steel framing; and
- ground rings.
In my own home, I can only see where there is one method used for this grounding, which is using a driven rod. The house is 12 years old and I don’t see where a second method listed above was used. How would I go about identifying what that second method is if I can’t readily see it? Any help much appreciated. If it can’t easily be determined, can anyone tell me which method is likely used here on the eastern seaboard? I’m thinking a ground to the well, but not sure how to tell.
