50amp on 120/208 service
I know most systems are setup on 120/240 systems but I need to have a plug installed in a commercial building that has 3 phase lines coming in and power options are 120 and 208. I don't see where tha...

Although the two phases are 120 degrees from each other, the phase to phase waveform still works out to be a sine wave, so it's "normal" single phase power albeit at a lower voltage. There are plenty of single-phase motors that are rated to operate at either 208V or 240V (and likewise plenty that are not so rated).
As long as the motor and it's load is designed for both power sources then all is good. Appreciate the input.
