In repair & testing scenarios, we use isolation transformers to remove
the Earth reference. It prevents ground loops arising which can destroy
sensitive test equipment. But an IT won't save you from a belt if you
somehow manage to bridge directly across it.
No it won't, but it won't make it any worse, it'll be identical. But it
does remove the shock from live to ground, which is more likely as only
one conductor has to be touched.
Er, that's what I said.
