Abstract
An electrical hazard detection system is used to detect energized ground terminals on electric receptacles. This condition may not be detectable by traditional circuit testers when hot and neutral wires have been switched and ground terminals have been electrically connected to the neutral wires. The user's body is used to provide a high-impedance path to true ground thereby creating an electric current from an energized ground terminal, activating a transistor, and illuminating an associated indicator.
