BigB,
How often would a situation like you've pictured occur?
I'm of the understanding that most tools and appliances these days are Class II (double insulated) and have no reference to ground, whereby they have a plastic body and no ground conductor.
Yes I can understand that there might be some Class I appliances still out there, but if people are going to use them, would they not use an in-line GFCI/RCD?
I imagine it is rare to non-existent, but by the same token how often would the ground rod do anything beneficial? Yes GFCI protection is required but you can't control what Joe Public does. We still have kitchen re-modelers here who don't bother to install them.
