I hear people talk about short circuiting a 120 volt circuit when that is impossible as the only way to short circuit something is line line to line. If you go from line to ground that is a fault not a short circuit.
With all due respect, you did not answer my question. You maintained that a 240v GFCI will not protect person, but only protect equipment. That contradicts the collective wisdom of this board. I know that there are some 240v GFCIs that will not trip fast enough to necessarily save one's life, but that does not mean it is so for every 240v GFCI. I am open to the possibility that you are correct, but you need to explain the logic behind your statement. So again, why would a 240v GFCI with 5 milliamp sensitivity not protect one from electric shock?
