I'm not arguing against any of that. I think my point is being missed because I'm not good at explaining things. My point, ultimately, is grounding things doesn't necessarily make them safer, much as ungrounded things doesn't necessarily make them dangerous. I sometimes get calls from customers about home inspections that note ungrounded receptacles. As much as I would like to say just rewire the house, honesty wins. I told one recently that it be ideal to have new wiring, but the reality is that it would be really hard to get shocked on a carpeted floor inside a house.
