Abstract: A work machine using a direct current power system that isolates reactive loads is described herein. The work machine uses a machine power distribution unit that receives direct current power from two or more battery banks of a power unit, whereby each of the battery banks deliver electrical power on a separate direct current bus. A machine power distribution unit of the work machine receives the electrical power from the battery and is used to isolate the power using bus connectors. One of the battery banks provides power to one direct current bus of the work machine and another battery bank provides power to another direct current bus of the work machine. A reactive load serviced by one of the battery banks is electrically disconnected from another reactive load serviced by the other battery bank.
