A system for distributing continuous, uninterrupted power to one or more critical, interdependent electrically powered devices comprising at least one power source; and at least first and second independent power distribution paths from the power source to the critical device or devices where power is consumed. This invention allows the protected electrical load(s) to continue functioning without interruption despite a power interruption or disturbance in a single power source and/or in a single power distribution path. The invention also allows one power source and/or one power distribution path to be taken out of service for maintenance or modification without causing a power interruption to the critical loads being served.
