In Wye-Delta, The three phases or hot wires plus a center tapped neutral comes from the transformer. 120V, 208V and 240V.įor high leg delta power, the electric power providers install three transformers Wye-Delta or Delta-Delta (we will discuss Wye-Delta for this tutorial due to 120V, 208V and 240V, 1 & 3 Phase Supply) or two transformers in Open delta configuration for smaller loads which still needs three phase power supply. The main advantages of the high leg delta system is that there are three types of available voltage i.e. 
High Leg Delta (also known as Power Leg or Wild Leg) is a three phase, four wire power distribution system used in commercial buildings in North America especially in rural and older installations.
