Claim:
1. A multidirectional electrical power protection system, comprising: first and second power supplies configured for supplying power to a main bus circuit; first and second load buses electrically connected to each of the first and second power supplies via respective connections with the main bus circuit and configured for energizing at least first and second devices; first and second smart contactors connected in series to the main bus circuit between the respective connections of the first and second load buses with the main bus circuit and the first and second power supplies, each of the first and second smart contactors being configured for sensing a first current flowing in a first direction through the main bus circuit and for sensing a second current flowing in a second direction through the main bus circuit and respectively including first and second logic controls each in communication with a sensor for delivering an output signal for opening the corresponding one of the first and second smart contactors in response to the sensing of an overcurrent flowing in either of the first or the second directions via the sensor; first and second power supply contactors electrically connected to the first and second power supplies in series with the connection of the first and second load buses with the main bus circuit and the first and second smart contactors, respectively, and an nth load bus with an absence of power supply or smart contactors electrically connected to each of the first and second power supplies via a connection with the main bus circuit between the first and second smart contactors.
