I am installing a Delta Delta Transformer for one piece of equipment. Primary is 3 phase 480 volt, secondary is 3 phase 380 volt. I am confused about grounding the secondary. Do I need to establish a ground? If I don't establish a ground and a phase conductor goes to ground nothing will happen until another ground fault occurs, right? Do I simply take B phase to ground?
Thanks in advance
