Circuit overload occurs when more amperage flows through an electric wire or circuit than it can handle. This may happen if you connect malfunctioning or defective appliances. Loose, corroded wires or connections may also be to blame. Once the GFCI outlet senses an overload, it trips or “breaks” the circuit.
How long should a GFCI outlet last?
about 10 years
Electrical safety check
All GFCI outlets have one little-known flaw: their circuitry eventually wears out, usually after about 10 years, at which point they no longer function properly.
