Hovering your mouse over different labels will show you the calculations used or the code sections referenced for the information. 

Voltages for the motors are taken from tables in section 430 of the NEC©. Use 115, 200, 208, 230, 460, 575, and 2300 volts when using the HP option.

120, 277, and 480 are used for the AMPS and VA options.

MotorThem can also give you the VA, OCPD, and disconnect size when you supply the Amps, such as from a HVAC device that has the MCA listed. If you input the VA, then it will return the Amps. If you know the VA, then it can give you the amps.
