got a plant that is currently supplied with a 3 wire 3 phase delta service. 240/480
installing backup generators
contractor wants to install 277/480y generators
aside from ALL KINDS of other obvious potential issues, right now i am concerned about any step-down transformers in the plant.
anything that would be going from 240/480 delta to 120/208 3 phase OR 240/480 delta to 120/240 single phase
what is going to happen if we feed these transformers that are on a Delta service with a Wye service during emergency backup conditions?
