The answer to 'why is my GFCI outlet circuit overload' is that a GFCI (Ground Fault Circuit Interrupter) outlet is designed to trip when it detects a ground fault or imbalance in the electrical current. This is a safety feature to prevent electric shocks and fires. However, a GFCI outlet can overload and trip for several reasons, including a short circuit, a faulty appliance, or too many devices plugged into the circuit.
Some common causes of a GFCI outlet overload include a malfunctioning appliance, a damaged power cord, a short circuit in the wiring, or an overloaded circuit. Symptoms may include the GFCI outlet tripping frequently, lights flickering, or devices not receiving power. To troubleshoot and resolve the issue, you may need to unplug devices, check for visible damage, and test the outlet with a GFCI tester. In some cases, you may need to call a licensed electrician to diagnose and repair the problem, especially if it involves issues with the home's electrical system.
