A circuit analyzer tests a power circuit including an earth leakage ground fault circuit interrupter, a receptacle, and a line, a neutral and a ground electrically connected between the circuit interrupter and the receptacle. The circuit analyzer includes a plurality of pushbuttons for inputting a plurality of test requests. A microprocessor outputs a plurality of test signals responsive to the test requests. A plurality of load circuits selectively provide a load between the line and the neutral responsive to one of the test signals. A display confirms tripping of the ground fault circuit interrupter responsive to the load, in order to determine if the neutral is electrically connected to the ground between the circuit interrupter and the receptacle.
