Generac STG6 Automatic Transfer Switch 3 Phase 4 Wire 240V

The Generac STG6 Automatic Transfer Switch is an 800-amp, 3-phase, 4-wire device designed for 240V electrical systems. As an automatic transfer switch, it switches power sources without manual intervention, helping maintain service when the primary source changes or fails in a 3-phase, 4-wire 240V configuration. The unit carries model number STG6 and the Generac name, signaling it is built for larger, multi‑phase installations requiring reliable automatic power transfer. With an 800-amp rating, the STG6 is designed for demanding loads common in commercial or industrial setups that rely on automatic source switching at 240V. The 3-phase, 4-wire configuration indicates multiple hot legs plus a neutral, aligning with typical 240V 3-phase electrical distributions.
