Tamper-resistant self-testing GFCI receptacle. Continuous self-test functionality - disconnects power to receptacle if critical components are damaged and GFCI protection is lost - providing “continuous self-testing” that initiates within 2.5 seconds and is a continuous cycle every 30 seconds or less. Manual test - this design incorporates a full system test function. The GFCI, when manually tested, induces a simulated ground fault leakage current to the printed circuit board. This in turn causes the mechanical system to react based on the action of the solenoid. The entire mechanical and electronic GFCI system is reviewed for functionality.
