That was (almost) my faulty thought too at first, but it turns out that the 2-phase system referred to comes from a single transformer with two secondary windings. This gives you two 120V lines wrt. neutral (L1 and L2) which are 180 degrees shifted. Therefore, the difference between L1 and L2 is 240V. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
