Now that we seem to be in agreement that we are not using earth for
return current, but we are using earth as a reference point for some
wires, I think we are back at the original question.... Is a
ground-referenced system more safe or less safe than a system that is
not ground referenced? If less safe, why was a ground referenced system
chosen? I don't have a clear answers to these questions.
