| Today, many of these buildings are being converted to multi-use commercial | application, where most of the loads are single-phase. They either add | 480-240/120 single-phase transformers feeding various panels, or replace the | service with 208/120. In the latter case, the few three-phase loads, such as | elevators or a/c, run on the 208 with no problems.
I hope they are using motors rated for 208 volts. I've been involved in a couple cases of motors burning out because they were getting 208 volts and were not rated for it. But given that 208Y/120 is common, I would think lots of motors, especially three phase models, would be available for the voltage. The cases I was involved with were single phase motors.
