The 480-volt system will power most of the equipment within the plant by quantity. Like most industrial facilities, OPEN100 utilizes an low voltage electrical distribution system for equipment below 1,000 volt, and 480 volt equipment is exceedingly common. The 480 volt system benefits from the resiliency in the 4,160 volt system which powers it, but also features a redundant distribution center in case of equipment failure in the 480 volt system.
