Abstract
A low cost, low parts count electronic circuit that is built into an appliance automatically and continuously checks for an open ground condition or a condition where the power conductors are transposed, at which time, power is interrupted in the appliance. By combining this with an electrical leakage detection circuit and power interrupter at the plug, the electrical safety of the appliance is greatly enhanced.
