| Why does everyone think the voltage is 110/220??

| If that actually was the voltage you had in your house you'd be very
unhappy.
| The nominal voltage is 118/236 with a +/- 5% range so you can see
that 110/220

| Well, duh, John!

According to my fuzzy memory Delta is 208 and since there isn't a
neutral or center reference 110 is not available. Y configuration gives
you 220 from leg to leg while from each leg to the common center
(Neutral) gives you 110. From there you go to how the transformers are
configured, I.E. Delta/Delta or Delta/Wye or Wye/Delta. All of which I
do not remember how each effects the voltage result.
