Did you know a circuit breaker is not designed to protect against a ground fault?
Circuit breakers are designed to protect against high levels of electrical current caused by a short circuit. Ground Fault Circuit Interrupters (GFCIs) protect against ground faults, when current leaking from an appliance goes to ground through a person touching the appliance. Even a small amount of current passing through a person this way can be lethal; a GFCI will trip if there's a ground fault, whereas a circuit breaker won't.
