Yes, tiptopper... You r correct in your thinking... The higher the voltage, the lower the amperage, all day long... You can figure these amperage, voltage, resistance, or wattage questions out easily using Ohm's law formulas: P = I X E, and E = I X R, P-Power, or Watts, I-Current, or Amps, R-Resistance, or Ohms, and E-Voltage, or Volts... A 220VAC supply would reduce your ampere draw on any mullti-tap ballast, that can also be wired to work on 110VAC, which will ALWAYS pull more power... You can load up your circuits to about 80% of the rated load... In other words, a single pole 20A breaker will safely carry a 16A load. And you can out however many ballasts on that circuit as 16 amps will allow you to, not going over the 80% load, or 16 amps in this hypothetical case...
