The 2nd ground messes it up

And the voltage configuration of sources is also wrong, which is a strong indication you better not publish dangerous circuits like this.

I've changed the voltage in the sources to 10v so there's no confusion.

So, you're basically saying that the voltage configuration in this circuit is wrong? Well, let me tell you that first of all you have no idea where I live so you can't be sure about that. (Europe ) Second of all you're right this time it is indeed wrong, but that doesn't make it dangerous, because it is just a demostration circuit and it is not meant to be built. Anyways, you should never build a circuit that you don't know how it works.

Even i dont know were you live, i know it is wrong! 163VAC is not 230VAC as you are saying in the headline. In no country world wide 163VAC are used. That easy i know its wrong. And dangerous are any voltages above ~40V. And your original voltage setup was 230V peak!

Hurz, as I said it is just a demonstration circuit, it is not meant to be built.

Fair enough

So better stay away from 230VAC as long you do not know its 325V in peak and peak2peak even 650V!

Even worse a delta shock. 1126 volt peak to peak.

325V * sqrt(3) = 563V

@hurz, to convert peak to peak, its peak voltage* 1/sqrt(2), or peak voltage *.707... so it would really be 325*.707=229.775, or ~230 vrms. Just like in the us, the peak voltage is actually like 169.73, take the root mean square of that, 169.73*.707~120 vrms.

Sorry to convert peak to rms... that's how the first sentence should read.

@justinmh, my last comment does not converted peak to rms. I calculated two sin voltages in 120degree phaseshift relation. And this is sqrt(3). Hope this helps.
