WebWhen a GFCI outlet keeps tripping, there must be a reason. Instead of just resetting the GFCI, you should also investigate the cause of the trip. Ground faults occur when electrical current finds an unintended path to ground. The usual suspects for ground-faults include worn insulation, conductive dusts, water, or other "soft grounds." dickeys south lebanonWeb14 de mar. de 2024 · How does a GFCI Work? A ground-fault circuit-interrupter is not an overcurrent device like a fuse or circuit breaker. GFCI’s are designed to sense an imbalance in current flow over the normal path.
