Re: sub panel
Ed If you have a 3-phase 120/240 service you have 208 volts on the "B" (center leg) phase to neutral and not 120 volt's so you have to use "A" and "C" phase. Are you sure the service is 120/240 or is it 120/208?

Re: sub panel
Here, when our utility used to supply a 4-wire delta secondary, we were required to install a separate panel for single phase loads.
