Two separate 150kVA 120/208 3-phase gas-powered generators can indeed feed a 1200 amp 3-phase AC electrical service, provided they are properly synchronized. Key considerations include ensuring that both generators maintain the same phase angle, voltage, and frequency to avoid operational issues. Additionally, potential harmonic distortion from separately derived systems must be evaluated to prevent voltage irregularities. Each phase voltage will remain at 120V when correctly combined, without resulting in 208V or 240V outputs.

Sparky1550 said:Can I feed a 1200 amp 3phase AC electrical service with 2 separate 150kva power sources? (the sources being 150kva 120/208 3phase gas powered generators) Are there any issues with harmonics from separately derived systems? Will each phases voltage still be 120v or by combing 2 separately derived phases will the voltage become 208v or 240v etc?
