The 15A limit in the circuit breaker is there to protect the wires, not you. 15A at 110V passing through your body will cause massive damage and literally cook you after stopping your heart if it's in the way. Modern circuit breakers and outlets have GFCI/AFCI electronics that detect abnormal current leaks to ground and abnormal waveforms, and shut off the circuit. These actually stand a chance of saving you in a scenario like this.
