1. A circuit breaker configured to connect to at least one downstream electrical connection, the circuit breaker comprising:
first at least one controlled switch configured for electrical connection between a hot power line and the at least one downstream electrical connection;
second at least one controlled switch or a connection configured for electrical connection between a neutral power line and the at least one downstream electrical connection; and
a processor configured to determine an internal component failure of the circuit breaker by:
coupling a constant current source to the circuit breaker, and
determining that the circuit breaker failed to open one of the controlled switches when a sum of currents of the at least one downstream electrical connection is greater than a neutral current of the neutral power line of the circuit breaker by a predetermined threshold.
