The answer to 'why is my GFCI outlet' is that a GFCI (Ground Fault Circuit Interrupter) outlet is tripping or not working properly. This can be caused by a few common issues, including a ground fault, a wiring problem, or the GFCI itself being faulty.
Ground faults occur when electricity escapes the normal wiring path, often due to damaged or exposed wiring. This can create a shock hazard. The GFCI is designed to detect these faults and cut power to prevent electric shock. If the GFCI is tripping, it's a sign that a ground fault has been detected and the issue needs to be addressed.
