Abstract
A sensing configuration for a ground fault circuit interrupter for devices having an internal or floating ground electrically isolated from an external ground. The sensor includes a conductor connected to the internal or floating ground so that EMF and leakage current are detected, thus preventing the ground fault circuit interrupter from tripping due to signals caused only by EMF and leakage current in the load circuit.
