The purpose of having grounding pin on AC outlet is to ground metalic surfaces of appliances so that there can be no voltage to hurt anyone even if there is a leak. Right?
If an AC outlet has the ground and neutral reversed, would it cause any problem? If an AC outlet has no grounding wire (old house) and instead the ground prong is connected to the neutral, would that cause any problem?
Is neutral connected to ground at the circult breaker panel?
