Hello All!
I have a 15KVA Transformer (480 Primary and 240/120 Secondary). I need 240V to run an air handler unit in an industrial environment. I connected the 480V primary from a 480/277 3-phase panel. I connected the secondary in accordance with the diagram. Without any load, I get 240V when I check X4 to X1. I have interconnected X2 and X3 per the diagram. Do I ground X2 and X3 to the ground inside the transformer panel? There is a ground block inside the transformer panel with a green wire from the transformer.
I guess my question is: What and how do I ground this thing? Is there a neutral here?
Sorry, I'm a newbee trying to do something safely.
