I have a Ryobi 2200 inverter generator I inherited from my dad. I did some work and finally got it up and running. The owner's manual says the generator must be grounded before using. That sure seems odd to me and to surely takes away from the portability of the generator. Anyway, I don't know much about grounding. I live close to a beach and have very sandy soil .I "think" there is a layer of clay about 4 feet down, but I don't know that for sure. I don't expect it will be difficult to drive the recommended 8 foot rod into the soil here, probably just using a hammer. I'm wondering if my sandy soil will provide proper grounding?
