PROBLEM TO BE SOLVED: To provide a power supply equipment of high reliability, wherein the number of feeders is small, durability against troubles is ensured, faults are excluded, and power supply can be continued. SOLUTION: In a power supply equipment for a vehicle, a main power supply distribution equipment 1 is connected with subordinate power supply distribution equipment 3, 4, 5 by using a main feeder 99, a preliminary feeder 109 and a data transmission signal line 200. For example, the subordinate power supply equipment 3 normally connects a relay switch 32 with a contact C1, and supplies electric power to a load L from a battery 18, through the main feeder 99. When a fault point (a) is detected in the main feeder 99 by a current monitor 14, the relay switch 32 is connected with a contact C2, and electric power is supplied through the preliminary feeder 109. |
