Split-phase electric power - Astronomy
In this case, the transformer voltage is 120 V on either side of the center tap, giving 240 V between the two live conductors. In Europe, 230/460 V, 3-wire, single-phase systems are used to run farms and small groups of houses when only two of the three-phase high voltage conductors are available (it is cheaper to run two wires than three). ................
