Transcription: The electrical distribution system distributes power through a four bus system. The main bus is a central electrical conduit through which all primary voltage travels. The A, B, and C buses are routable electrical conduits which can be used to reroute power during emergency situations. Fuel cell one recharges the A battery through the A bus electrical subsystem. Fuel cell two recharges the B battery through the B bus electrical subsystem and fuel cell 3 recharges the C battery through the C bus electrical subsystem. During emergency situations, the bus tie-line circuit allows the crew to rerou ...
