This is what I asked in Sci.electronics.basics
Just curious!
I wish to change the phases using triacs - Three triacs are connected to the three pahses (220V). The other terminals are bound to the output. By firing selectively a triac the output is connected to the respective phase.
What will be the problem?
And Jamie said
Nothing except, you aint changing the phase, you're just deciding when

And finally Phil said (in his kindest moment)

So I defer to Phil
Any additional help will be most welcome.
