Westinghouse’s iGen8200TFc runs on gasoline, propane or natural gas. On gasoline it gives 8,200 peak and 6,600 running watts. Natural gas from a home line removes refueling from an outage.
Built for the house
A 120/240 V 14-50R 50 A outlet connects to a transfer switch or interlock kit, and Westinghouse names an air conditioner, a refrigerator and a sump pump running together. A 120 V TT-30R serves an RV. Power quality is under 3% THD, with copper windings.
Engine and run time
A 298 cc OHV engine with a cast iron sleeve runs up to 17 hours at 25% load on a 3.9-gallon tank. Remote electric start, a CO sensor and a digital display are listed.
