Question on the “Grounding Systems” section.
Why is it telling me that I need to add two separate grounds? I inspected 3 different homes in Florida and they all only have one grounding electrode.
2 grounds is the current standard for many areas. However you won’t find that on older homes.
We have many homes here that are only grounded to a water entrance pipe.
Where are you reading that two are required? Please post the article.
You need only one grounding electrode if it’s not a metallic water pipe electrode. If it is a metallic water pipe electrode then it must be supplemented by another electrode.
A Ufer or CEE is a standalone electrode. A driven electrode like a rod can be a single electrode if it is proven to be less than 25 ohms.
