An electrical distribution system is disclosed that includes a gateway module ( 100 ) including logic ( 112 ) to interface to a vehicle management computer (VMC) ( 50 ) via a dual redundant standard data bus ( 1 ). The gateway module ( 100 ) has redundant microcontrollers ( 114, 116 ) operably connected to the VMC ( 50 ) for selectively controlling supply of electrical power to a plurality of separate electrical loads ( 120 ). The electrical power distribution center also has two internal serial data buses ( 2,3 ) that are of two different types. The redundant microcontrollers ( 114, 116 ) are each connected to the two internal buses ( 2,3 ). A plurality of Load Management Modules ( 300 ) is provided. Each are connected to the internal serial data buses ( 2,3 ) for receiving control commands via the gateway module ( 110 ). Each Load Management Module ( 300 ) includes a local microcontroller ( 310 ); a plurality of power switching devices ( 320 ); and a plurality of application specific integrated circuits ( 330 ) corresponding to the plurality of power switching devices ( 320 ) for interfacing the power switching devices ( 320 ) to the local microcontroller ( 310 ).
