The answer to 'GFCI outlet replacement schedule' is that GFCI (ground fault circuit interrupter) outlets should be tested and replaced every 5-10 years, or sooner if they are not functioning properly. GFCI outlets are an important safety feature that help prevent electric shock and reduce the risk of electrical fires. They work by quickly shutting off power if they detect a ground fault, which can happen if there is a problem with the wiring or a faulty appliance is plugged in.
It's recommended to test GFCI outlets monthly by pressing the 'test' button, and to replace them every 5-10 years as a preventative measure, even if they are still functioning. Older GFCI outlets may become less sensitive over time and may not trip as quickly in the event of a ground fault. Replacing them on a regular schedule helps ensure your home's electrical system remains safe and up-to-date.
