  • Publication number: 20040070895
    Abstract: With prior art Immersion Detection Circuit Interrupters (IDCI), the firing of the trip coil to open the contacts which interrupts the flow of current to a load uses the neutral conductor as the return path when leakage is detected. If, however, the neutral conductor should become open, there is no return path present to fire the coil. An unsafe condition because the voltage that is present cannot be disconnected from the load. With this invention the SCR, which is used to fire the coil, now uses the ground conductor and diodes as the return path to fire the coil to interrupt the voltage from the load. A fully shielded cord is used to detect a break in a conductor. An LED indicator in either the plug or the receptacle of the extension cord verifies that protection is available. A test button is provided to test shield continuity and to verify proper circuit operation.

  • Patent number: 5864455
    Abstract: An in-line cord ground fault circuit interrupter which contains within a common housing the sensing unit and the tripping relay usually found separately packaged at a remote location. The fixed contacts are mounted on fixed contact arms mounted adjacent one surface of a printed circuit board with the movable contacts mounted on movable contact arms mounted adjacent the second surface. The tripping relay operates an armature between an open and a closed condition and by cams on the arms of the armature opens and closes the movable contacts with the fixed contacts. The two portion housing allows the components of the interrupter to be mounted on one portion of the housing which also supports the line and load conductors making assembly of the rear housing portion to the front housing portion easy. A stop member and a positioning post are provided on the interior of the front cover to check the position of the armature in the non-energized state to verify proper contact placement and gaps.
