  "description": "The GP8000E COsense is a conventional open-frame gasoline generator for home backup: 8,000 W running / 10,000 W starting (Generac's 'PowerRush' surge marketing is not conflated with the rated figure). Its 420 cc engine feeds a 120/240 V panel with an L14-30R twist-lock and two GFCI-protected 120 V duplex outlets. COsense carbon-monoxide shutdown is documented in the GP-series manual and reflected by the panel's Red/Yellow COsense indicators. Electric and recoil start; not parallel capable. Runtime is 15 h at 25% / 10 h at 50% load on the 7.9 gal tank. As a conventional AVR unit it publishes no numeric THD, and Generac lists no official dBA figure for it — both recorded as unknown. The 7675-4 is the 49-State configuration (not CARB certified; 50-State CARB SKUs exist separately as 7676-x).",
