    Split phases are equal magnitude and 180 degrees out of phase. Each phase is the opposite pole of a transformer and the neutral is a center tap. The biggest potential issue is with earthing.

    Indeed, universal machines won't have issues but induction motors may.

    if you still have trouble with the sine test, please tell us what frequency you want to produce, and we will see how to generate the necessary parameters for it.
