What are distribution voltages?

Distribution Voltages Primary lines have voltages ranging from 2,300 to 39,000 volts. Common primary line voltages are 2,300, 4,160, 12,470, 13,800, 25,000 and 34,500 volts depending on which distribution voltages a utility uses. Common secondary line voltages are 120, 208, 240, 277 and 480 volts.
