Abstract
Methods, systems, and computer readable media for providing protection of DC building electrical systems are disclosed. According to one aspect, a system for over-current protection of direct current (DC) building electrical systems includes a DC bus for providing DC power to a building and multiple DC feeder conductors for providing DC power to multiple locations within the building. Each DC feeder conductor is connected to the DC bus via a DC protection module having a fuse, a normally closed switch connected in parallel with the fuse, and a circuit breaker connected in series with the fuse and switch, where the switch is controllable to be closed to protect the fuse against transient current conditions and controllable to be open after the transient current conditions have subsided to allow the fuse to operate normally.
