A receptacle type ground-fault circuit interrupter (GFCI) device adapted for connecting to input lines, which includes a pair of input terminals for connecting to the input lines, a pair of receptacle outlets, a ground-fault current detector for detecting a ground fault condition on the input lines, a reset and trip device, and a self detecting and testing structure. The device further includes a normal working condition indicator and an end-of-life indicator. When the GFCI device is correctly wired and working properly, the device can be properly reset by a reset button. When the ground-fault is detected, the GFCI is put in a normal tripped state with no power output. When the input terminals and the output terminals are reversely wired, no power is output. If an input line is broken, no power is output.
