    Most DC motors that I have dealt with are compound wound. I know what happens but I'll leave for others.

    Why would you even consider paralleling the secondaries?

    We are talking about the time varying electrical wave forms here. Not reflections.
    The positive peak for L1-N occurs at a different instant in time to the positive peak for L2-N.

    Your reflection...
  4. Don't they reach their positive peaks at...

    Don't they reach their positive peaks at different times?
    Why is that not an offset in time?
  5. Doesn't that describe exactly what a phase shift...

    Doesn't that describe exactly what a phase shift is?

    Whether that time offset is 5.55 ms (120°) or 8.33 ms (180°), it is still an offset.

    Are they 180 degrees apart?
    That's just yes or no.

    I suspect that it probably is quite different.

    I suspect that it probably is quite different.
  9. Because they are 180 degrees out of phase.

    Because they are 180 degrees out of phase.

    They are 180 deg out of phase.
    Call it anything you want but it doesn't negate that point.
  11. But out of phase so they can't be the same phase....

    But out of phase so they can't be the same phase. Ergo, you have more than one phase.

  13. Aren't sockets rated in current rather than watts?

    Aren't sockets rated in current rather than watts?
  14. How can 120/240 be considered more than one phase...

    How can 120/240 be considered more than one phase if it is incapable of producing a rotational field?
    On the basis of that assertion............well I'm sure you can interpret it as you wish.
    In my...

    Let me remind you of your comment:


    My hexaphase rectifiers were static.

    With respect, the capability of producing a rotational field is not of relevance. I designed multi-phase high current rectifiers. No rotation involved.

    But that wouldn't be 120-0-120, would it..................

    Yes. Two. Displaced in phase.
    i.e. not the same phase.
  23. The 120-0-120 arrangement is two lines phase...

    The 120-0-120 arrangement is two lines phase displaced by 180° plus a neutral.
    I think we can all agree on that.
    :D
  24. Agreed.

    Agreed.

    Without earth leakage detection, the DC busbar voltage to float to any level with respect to ground.
    That puts people and kit at risk.
