Abstract: An apparatus for providing electrical protection and reducing power consumption in data centers. In an aspect, an apparatus includes a hot swap control circuit that monitors a voltage drop across a fuse, and selectively connects a bus bar to a load, based on the monitored voltage. Further, the apparatus selectively disconnects the bus bar from the load when the hot swap control circuit indicates that the monitored voltage across the fuse has attained a voltage threshold.
