Rich: Thanks for the excellent commentary. As I originally noted, my input was from about 20 years ago (and it could have been a subjective judgement/guess at that time by the Dr. teaching the course). I think we all have benefited from the discussion of this subject in that we need to clearly think out all facets of a potential safety issue. That is, how the safety concern arises, the physical connections to a person, the electrical paths involved, the impedance magnitudes involved, and the susceptibility levels asociated with those particular conditions.
