The answer to 'GFCI outlet power surge' is that a GFCI (ground fault circuit interrupter) outlet can trip due to a power surge, which is a sudden, unexpected increase in electrical voltage. This can happen for a few common reasons, such as lightning strikes, faulty wiring, or a malfunctioning appliance.
When a GFCI trips due to a power surge, it's designed to shut off the power to the outlet to prevent electrical shock or fire hazards. The symptoms may include the GFCI outlet not working, lights flickering, or other electrical issues. To resolve this, you can try resetting the GFCI by pressing the 'reset' button. However, if the problem persists, it's best to call a licensed electrician to inspect the wiring and identify the root cause, as power surges can indicate a more serious electrical issue that requires professional diagnosis and repair.
