Abstract
A ground circuit indicator has a very high resistance and low leakage current to ground. Accordingly, should the ground circuit not be connected, the voltage applied to the chassis of any appliance connected to the circuit will be low, and will not expose persons to a shock hazard. The indicator is adapted for use with multiple outlet connectors.
