Selling this on ebay. It's a Generac industrial SG150 series, 277/480V 3 Phase 225 amp, 60hz @ 1800 RPM. 187 kva. Manufacture date is 12/11/1998. It has ONLY 48 HOURS ON IT. Runs like a new generator. Powered by a 13.3L Hino 6 cylinder engine, runs on natural gas, 7-11" water column gas pressure and probably around 1.2 million btu's per hour needed when at 100% full load. The gas inlet is a 2" line... if that gives you any idea. 24 volt starter, takes 2 big 12V batteries in series. The controller compartment had a big mice nest in it so it took a lot of wire repair and cleanup to get it going again. There's a good amount of corrosion in the compartment but all the connections seem solid, it fires right up and stabilizes in about 10 seconds.
