Hot ground can If your multi-meter indicates a neutral to ground voltage, that could be due to any one of the following causes: 1. When the grounding conductor is connected, the electricity has a path to flow along which causes the breaker to trip. 0000001176 00000 n Should there be any voltage between neutral and ground? Neutral and Ground are not the same thing. If there is voltage between them, then there is a (large) current. 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.
