Abstract
To prevent overloading of a shared secondary power feed, active transfer switches are controlled to switch discrete hardware from the shared secondary to a corresponding primary power feed, even if such a primary is currently nonoperational thereby resulting in deactivation of such hardware. A threshold amount of power draw from the shared secondary is established, such as to ensure that failure of a single primary can be accommodated, and active transfer switches are controlled so as to prevent such a threshold from being exceeded. Alternatively, or in addition, active transfer switches are controlled such that they, in the event of an interruption in the power being provided by the primary power feed, either switch to the shared secondary or, in accordance with the aforementioned control, do not switch despite the interruption in power.
