And each phase individually has a voltage relative to neutral of 115V if you are in the US, and 230V if you are in most of Europe. Also the neutrals never are on the same bar as the ground wires in a sub panel, they must sit on a floating neutral bar, if using a regular panel tub as a sub panel you must remove the ground bonding screw from the neutral bar.so the metal panel and grounds are not touching the whites anywhere but back at the main panel. Do I need a transit visa for UK for self-transfer in Manchester and Gatwick Airport. Also if someone made a neutral ground reverse the ground system takes back the returning current and anything bare gets heated up, I think some kid got killed in a ground neutral reverse in Australia on some 230V when he turned on the hose and got between two grounds.
