In Reply to: Because most folks do not understand Ohm's Law. posted by Al Sekela on April 2, 2007 at 11:53:45:
If there God-forbid was a failure in a component, which would make the chassis "live" (the same potential as the "hot" wire, the code grounding would short the hot line to common, and trip the breaker before things become lethal. That same failure with the "isolated" ground would *not* tie it to common, but would have some "real estate" in between, providing too much resistance to trip the breaker. And the path of least resistance could end up being the unfortunate one who comes in contact with the live chassis. ("Isolated grounding" and "DIY" components can be a deadly combination.)
