| 134 | NOVEL CIRCUIT INTERRUPTING DEVICE WITH END OF LIFE TESTING FUNCTIONS | US11822562 | 2007-07-06 | US20080192393A1 | 2008-08-14 | Huadao Huang; Lu Huayang |
| The present invention provides a circuit interrupting device which comprises a novel reset mechanism to allow a user to test whether the device is wired properly. The novel reset mechanism includes a reset conducting apparatus which contains a reset start switch (KR-4). The KR-4 contains a first conducting pin, a second conducting pin, and a conducting bridge. When the reset button is depressed and the device is wired properly, the KR-4 is closed to allow the conducting bridge to be in contact with both the first and the second conducting pins so as to reset the device. The present invention also provides a circuit interrupting device which is capable of automatically checking the components of the circuit interrupting device (i.e., the end of life test) through a novel status test switch (KR-1). The KR-1 comprises a flexible metal piece and a simulated leakage current controlling resistor, which is located underneath of the flexible metal piece. When the circuit interrupting device is properly wired and at a tripped state, without touching any parts of the circuiting interrupting device, the KR-1 is closed which generates a simulated leakage current to allow the device to conduct the end of life test. If all of the components in the device are functioned properly, a reset indicating light is lit. | ||||||

| 137 | Ground fault circuit interrupter with blocking member | US11810341 | 2007-06-04 | US20070235300A1 | 2007-10-11 | Frantz Germain; Stephen Stewart |
| Located within a GFCI is a movable contact bearing arm which cooperates with at least one fixed contact. When the movable arm is moved up to allow the at least one contact on the arm to close with at least one fixed contact, the GFCI is in a conducting state and current flows from a source of electricity through the closed contacts to a load and to the contacts of a receptacle. When the movable arm is moved down to open the contacts, the GFCI is in a non-conducting state and current cannot flow from the source of electricity to either the load or the receptacle contacts. In this invention, the up and down movement of the movable contact bearing arm is harnessed to move a blocking member located within the housing of the GFCI to a first position to block at least one opening of the receptacle as the movable arm is moved down or to a second position to allow the prongs of a plug to enter the openings of the receptacle as the movable arm is moved up. The downward movement of the movable contact bearing arm occurs when the GFCI goes into a non-conducting state. Resetting the GFCI by pressing in and then releasing a reset button causes the movable contact bearing arm to move up to make contact with the at least one fixed contact. As the movable arm moves up, the blocking member moves to the first or non-blocking position to allow the prongs of a plug to freely enter the openings in the face of the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a non-conducting state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a non-conducting state and, therefore, the need for the bridge contacts is diminished. | ||||||
