The answer to 'lifespan of GFCI outlet' is that a properly installed and maintained GFCI (Ground Fault Circuit Interrupter) outlet can typically last 10-15 years on average. GFCI outlets are designed to protect against electric shock hazards by quickly cutting off power when they detect a ground fault or current imbalance. While they can last a long time, the internal components may wear out over time and need to be replaced for continued safety.
GFCI outlets should be tested monthly to ensure they are functioning properly. Over time, the internal components can become worn or damaged, reducing their effectiveness. It's recommended to replace GFCI outlets every 10-15 years, or sooner if they fail the monthly test or show signs of damage.
