Abstract
An electrical distribution control system for a vehicle such as an aircraft may be provided fire-suppression protection without requiring that all control elements are located in a fire-containment enclosure. A primary electric load center (ECL) may be located in a fire-containment equipment bay. Secondary power control centers (SPC's) may be located away from the equipment bay and close to set of loads which are controlled by the SPC's. Each SPC may be provided with a fire detecting sensor that may signal the ECL to interrupt input power to the SPC in the event of a fire in the SPC. The SPC may be constructed from self-extinguishing material. In an absence of input power to the SPC, a fire may self extinguish, thus preventing flame propagation or production of excessive external heat.
