Wiring a GFCI outlet backward—specifically by reversing the incoming hot power wires from the electrical panel into the terminals labeled LOAD instead of LINE—results in severe operational failure. While the outlet may appear normal initially, pressing the TEST button will either fail to trip the device or leave downstream connected receptacles completely unprotected, and the reset mechanism may jam permanently. Furthermore, this improper installation violates National Electrical Code safety mandates and creates significant electrical shock risks. Verification: Use a plug-in circuit analyzer to verify correct wiring and ensure the trip function correctly cuts power to both the face and downstream outlets.
