The answer to 'GFCI outlet keeps tripping' is that a GFCI (ground fault circuit interrupter) outlet will trip when it detects a ground fault or electrical imbalance, which is a safety feature to prevent electric shock. Common causes include faulty appliances or devices plugged into the GFCI, moisture or water exposure, a short circuit, or a ground fault in the wiring. Symptoms include the GFCI outlet repeatedly tripping and power being cut to the circuit.
To troubleshoot, first unplug any devices from the GFCI outlet and reset it. If it trips again, there may be an issue with the GFCI itself and it will need to be replaced by a professional electrician. If it holds, plug in devices one at a time to identify the culprit. Ensure that the GFCI is not being overloaded and that there is no moisture or water exposure. For more complex issues like a ground fault in the wiring, it's best to call in a licensed electrician to diagnose and repair the problem.
