1. A circuit breaker comprising:
a line phase terminal;
a load phase terminal;
a line neutral terminal;
a conductive path formed between the line phase terminal and the load phase terminal, the conductive path having an open configuration and closed configuration;
a sensor;
a linkage configured to move the conductive path between the open configuration and the closed configuration;
a rocker selectively engageable with the linkage, the rocker configured to move the linkage between an open position and a closed position; and
an arm selectively engageable with the rocker, the arm to prevent the conductive path from moving to the closed configuration unless the circuit breaker passes a self-test when movement of the rocker is detected;
wherein a trip operation of the circuit breaker includes a time delay based upon an amount of current on the conductive path detected by the sensor.
