A persistent DC circuit breaker provides a persistent single or dual DC voltage for a power distribution circuit coupled to a power panel. A control mechanism ensures a constant and consistent DC power output from the persistent DC circuit breaker. The persistent DC circuit breaker can replace an AC circuit breaker to convert an AC power panel into a coexisting AC and DC power panel or an entire DC power panel.
