El Faro had two steam turbogenerator sets manufactured by Terry Steam Turbine Company. According to data recorded by El Faros VDR, the generators continued to produce electrical power until 0734 on October 1, just before the vessel sank.Each turbogenerator consisted of a steam turbine, powered by 900 psi of superheated steam, that was coupled by a set of reduction gears to a General Electric marine alternating-current generator operating at 1,800 rpm. Each generator had a capacity of 2,000 kilowatts of three-phase power at 450 volts and 60 hertz. The main 450-volt switchboard was energized by the two turbogenerators'. The emergency switchboard, in the emergency generator room, was fed from the main switchboard through an electrical tie.
