[QUOTE=jproffer;310729]Not to be argumentative, but that's absolutely...180°...100%...wrong.

The hots MUST be on opposite phases and have means to be simultaneously disconnected. This way the nuetral only carries the difference between the loads. If both hots were on the same phase, it would carry the sum of the loads and (possibly...maybe even likely) be overloaded.

NOT SO.

From Northernboy's Schematic: If you draw a line loop from Leg B to the neutral & then another line loop from the Neutral to Leg A you will note that the current in the neutral is the difference between the two legs. The current from Leg B thru the neutral is going downward. The current from the Neutral to Leg A is going upward. Therefore the current in the neutal leg is the difference between the two leg currents.

The circuit from Leg B to Leg A is indeed ONE Phase. NOT MULTIPHASES.
