Eaton GFCI self-test tamper resistant Duplex receptacle provides protection from dangerous electrical shocks caused by ground faults. Our GFCI devices automatically self-test periodically to ensure GFCI protection and continuous safety. In addition to being tested to the highest standards to help ensure safety, Eaton GFCIs will deny power and prevent re-setting if the device is no longer able to provide safe, protected power. The built-in indicator lights provide quick notification of a tripped or “end of life” condition. Additionally, tamper resistant (tr) GFCIs feature a built-in UL listed safety shutter system that prevents the insertion of foreign objects into the receptacle openings.
