Ground Fault Interrupt (GFI) Controllers, Fairchild SemiconductorGround-Fault Circuit Interrupter is a low-power controller for AC-receptacle, that detect hazardous current paths to ground and ground to neutral faults. The circuit interrupter then disconnects the load from the mains power line before a harmful or lethal shock occurs.Ground Fault InterrupterEarth Leakage DetectorRequire less adjusting and calibratingGround Fault Interrupt (GFI) Controllers, Fairchild Semiconductor
