1. A fail-safe electronic circuit breaker comprising:

  • a fault detection circuit for detecting a circuit fault;

    a test circuit connected to the fault detection circuit, the test circuit selectively generating a simulated circuit fault;

    a trip mechanism connected to the fault detection circuit and the test circuit, the trip mechanism tripping the fail-safe electronic circuit breaker when the circuit fault is detected by the fault detection circuit; and

    a trip mechanism disabler connected to the trip mechanism and the test circuit, the trip mechanism disabler permanently disabling the trip mechanism when the fault detection circuit fails to detect the simulated circuit fault after about a predetermined amount of time.
