Yeah, I said exactly that is so many words and the input is still three phase. They installed the secret control box and they just say it modifies the wave form. But the output is not two wire as opposed to three. So that is single phase AC or could be pulsating DC depending on the wave modification. Pulsating DC is good for induction loads...among other things....TV oscillators.....amplifiers and other stuff...
Here’s another Vortex thread where the output for 2wire versus 3wire led to the secret wiring hypothesis, AFAIK

With so many threads to drill down on, you can see my reluctance to get into this material. But, you’re in luck, because you can sign up at Vortex and save the world from this supposed scammer as long as your explanations hold up. Best of luck.
