High leg delta The three phase power is connected in the delta configuration, and the center point of one phase is grounded. This creates both a split phase single phase supply (L1 or L2 to neutral on diagram at right) and three phase (L1 L2 L3 at right). It is called "orange leg" because the wire is color coded orange.

The two bus bars are 120 volts line to neutral, the wild cat red leg is 208 volts line to neutral. How to Wire a 3 Phase Motor | Hunker The voltage cycle of each line lags its predecessor by 120 degrees L2 reaches its peak voltage after L1, and L3 reaches its peak voltage after L2. Two wiring configurations, Wye and Delta, indicate the wiring methods for three phase motors. These instructions cover a dual voltage, three phase motor, the most common type. Easy understanding of 3 phase transformer connections ... In other words, a high voltage winding and a low voltage winding that are drawn parallel to each other constitute a single phase transformer or two windings on the same leg of the magnetic core of a three phase transformer. I learned I have 3 phase "high leg" at my new location ... 3 phase machines with low voltage controls require that you identify the high leg and make sure it is not feeding the control transformer. Connect either of the low legs to the transformer, and note the tap. Some are tapped for 208, 277, 120, etc.. The other two can be swapped to make your machine rotation is correct. Four Wire Delta Circuits – Continental Control Systems, LLC The high leg or phase with the higher voltage as measured to neutral has traditionally been designated “Phase B”. A change to the 2008 NEC now allows the high leg of a four wire three phase delta service to be labeled as the “C” phase instead of the “B” phase. How to check a 3 phase motor system How to check a 3 phase motor system. This addresses the 3 phase motor in the system. Working through the system Motor to disconnect,overloads, contactor and fusses. Can a 3 phase QO load center be used on a 240V ``high leg ... These may be applied on any of the phases, including the high leg phase. NOTE: The installer should be careful to follow NEC and or local electrical codes regarding the wiring, marking, and usage of this system.
