This is a photograph of the data/specification plate on a Caterpillar generator set, not a Ford automotive document. The nameplate identifies the unit as a CATERPILLAR GENERATOR SET with engine model 3306. Ratings shown include 288 kVA prime, 230 kW (standby box checked), 0.8 power factor (COS Ø), 60 Hertz, continuous duty, 3-phase AC. The GENERATOR DATA section indicates a 12-wire machine with WYE connection checked (Delta/Parallel options unchecked, Series marked X), 240 volts at 694 amps output, generator excitation of 38 volts at 7.1 amps, a 446 frame, and 1800 RPM operation. Maximum temperature rise is stated relative to 40 °C ambient with Class H insulation. The lower portion of the plate (enclosure type and additional lines) is obscured by corrugated conduit and hoses crossing the label. From this plate a reader can determine the genset's electrical output ratings, connection configuration, frame size, speed, and insulation class. The photo was filed under a 1991 Ford LTD Crown Victoria gallery, but the document itself clearly pertains to Caterpillar generator equipment.
