After reading some of the posts on grounded and ungrounded systems, it reminded me of an old conversation I remember reading about the push for ungrounded systems (with monitoring) in residential. Something similar they use in hospitals, but not as robust.
Of course this would most likely never happen in the U.S because we are too far set up for grounded systems in our grid.
But it was an interesting concept to see the theory behind it, especially the argument for it in swimming pools (or at least have a sub panel of ungrounded systems). It was suggested that ungrounded systems with monitors be used for swimming pools and close to marinas. They said the alarms would go off immediately when there is a voltage being grounded in the pool and this would be caught sooner rather than later and would possibly save more lives.
The costs involved in installing these ungrounded systems I believe would be too much for some to even consider this concept. But it did have me thinking about it. Most shocks I know of are when someone has been grounded and came in contact with higher voltage potential. Very rare do I hear of a hot to hot or phase to phase shock.
What do you think of this idea of ungrounded systems with monitors for pools?
