ECN Forum Forums General Topics of the Trade General Discussion Area 120/208 and 120/240 sinlge phase

Can somebody post the diagram for a three phase Y 120/208 transformer bank hook-up and a single phase 120/240 off the same bank. I understand you can use 120/240 single phase pots and not cut the middle pot but increase its size to handle the 120/240 single pase loads.
