Buck Boost Electronic Calculator, Calculates proper Square D Transformers to use when doing small changes in voltage: 5%, 6.6%, 10%, 13.3%, 20%, and 26.6%

• Step One: Single Phase or Three Phase Application
  IF Three Phase:
  
  • Three wire source: Must use Open Delta
  • Four-wire source:
    • Use Open Delta if only need three wires for load
    • Use Wye configuration for all four-wire applications.
      Note: Wye configurations offer expanded kVA Capacity - so try if Open Delta does not meet your requirment.
• Step Two: Input Source Voltage
• Step Three: Start changing the voltage change percentage until desired voltage appears in either the buck or boost windows (Exact voltage might not appear, please pick closes voltage: 240 required from 208, 236 is closest voltage)
• Step Four: Choose the voltage that will be used. (Buck or Boost)
• Step Five: Input Load Amps
     Calculate Load Amps by inputting Load kVA
• Step Six: If source is 50HZ click yes for required

Calculator will then calculate Proper Square D Buck Boost Transformer and wiring diagram.
