ABSTRACT:
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-4contains 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-4is 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-1comprises 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-1is 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.
