Abstract
The present invention provides a circuit interrupting device, preferably a ground fault circuit interrupter, which provides a quick and reliable connection/disconnection of electrical continuity through a combined use of a reset spring and a quick trip spring; an innovative circuit interrupting assembly containing a pair of input flexible metal pieces, a pair of user accessible load flexible metal pieces, and two pairs of fixed contacts on the load terminals; an automatic end-of-life testing mechanism by way of a simulated leakage current metal piece assembly; a reverse wiring protection by way of a reset start switch; an electrical surge protection through a power discharge mechanism; and a periodical end-of-life testing using a timer chip.
