How to Install a Ground Fault Breaker A ground fault circuit breaker is properly called a ground-fault circuit-interrupter breaker, or simply a GFCI breaker installs into a home's service panel, or breaker box, and provides GFCI protection for the entire branch circuit it serves. Earth Fault Indicator Circuit - ElectroSchematics Earth Fault Indication Circuit Diagram The circuit is directly connected to mains to monitor the status of the connections. Earth connection is a must in domestic wiring to bleed current to the earth if the metal body of a device is accidentally touched with the phase line. Short Circuit vs. Ground Fault A ground fault is a type of fault in which the unintentional pathway of the straying electrical current flows directly to the earth (to ground). Here, too, the circuit is "short," in that it has bypassed the circuit wiring, so a ground fault can technically be defined as one type of short circuit.
