208 Volt 2-wire is generally achieved by pulling two hot wires off 3-phase 120/208 Wye or 208 Delta, or Highleg to center tap off high leg delta. http://waterheatertimer.org/How-to-wire-3-phase-electric.html http://waterheatertimer.org/images/3-phase-timer-diagram3-T104-208-240.jpg
Since each of these three phase systems also offers 120volt for lights, and a dimmer can be used for lights, then I wonder what you are using dimmer for?
208 volts.can be controlled by turning off one hot of the two hot wires. Install dimmer on one of the hot wires, and see what happens. Is the dimmer rated for 208 volts?
