480 to 208 transformer wiring.

Step-Down Transformers reduce electrical voltage in an application. The 3-Phase design is more compact, cost-efficient, and lighter than three individual single-phase units used together. This design also promotes more efficient use of base materials, such as copper and iron ore. At Agile Magnetics, we use 100% pure copper windings to construct ...jsciarlo said: The tranformer that is there is a 460 primary to 120/240 secondary. Oh, so the main service is 480.
