Abstract
A circuit interrupting system has an upper cover, an intermediate support, and a base. A mounting strap is installed between the upper cover and the intermediate support, and a electric circuit board installed between the intermediate support and the base. The upper cover includes an electric output plug, a test button, and a reset button. The mounting strap includes a ground point that is connected to a ground receptacle of the electric output plug; the intermediate support on both sides a pair of output conductors. The electric circuit board comprises a differential transformer, a solenoid coil having a plunger inside, a reset button bias member, and a flexible switch; both sides of the base respectively comprise in parallel a pair of electric input connection screws and a pair of electric output point. The ground fault circuit interrupting system is installed within an output box on the wall of an ordinary household which prevents hazard caused to human and household electronics by errors in the installation of the connection lines.
