I don't think there is any specification for minimum distance from the structure. It just has to be driven in a full 8 feet. Probably you will want to avoid driving it through the footing, though I suppose you could if you pre-drilled it. In your case, maybe you want to run the ground wire around the corner to a more convenient place to install the ground ...

It is fine to drill a hole in pavement to drive the rod. How do you attach clamps and wire if it is driven flush? My city inspector wanted to be able to see the manufacturer's stampings on the end of the rod to prove that I had not cut it off short (providing less than required soil contact), I was specifically required to leave several inches exposed.

There is no reason to provide accessibility to a supplementary grounding electrode and the code requires it to be at or below surface. The important point of the code is that the supplementary electrode be driven so that it has at least 8' of full contact with the ground. Excavating and backfilling are likely to reduce the effective contact.

The grounding electrode conductors can be used to allow installation of the grounding electrode sufficiently far from the structure to avoid the footings. There is little point in speculating in regard to the size and configuration of existing foundations. However an reasonable estimate might be made using excavations on one or more other areas of the ...

I know when the home I live in now was built (mid 60's) grounding was not required for lighting circuits in my area. The electrician that wired the house actually pulled the grounding wires back out of the box (non-metallic) and bound them together behind the box. So none of my lights or switches in the house are grounded. It would be safer to have the ...

In a perfect world, with perfect electronics, there would be no need for a grounding conductor. It's there to deal with imperfections. The most likely case for a ground fault in this installation would be if the black conductor lost some insulation and shorted itself against the frame of the fan. In such a situation, the casing could become electrified, ...

It's unlikely that your service panel ("circuit breaker / fuse box") is not grounded. That could lead to all sorts of weird problems, not to mention that it would be tantamount to malpractice for an inspector and an electrician to walk away from an electric service in that condition. Furthermore you said that some outlets are grounded. If they passed ...
