Greetings All,
I have a question about sizing a transformer. I've tried looking online and using my understanding of ohms law but I keep getting different answers.
Here's the deal. I need to supply 400amps @ 120V. It will be fairly simple to balance the loads so is there any benefit to setting up the panel as 230/3 phase? (125amp per leg) (Yes I know we'll need a Neutral to get 120V)
If my understanding is correct, using this method will allow me to get away with a 75KVA transformer.
Bottom line, there's plenty of capacity at the 460V main. The guy putting in the transformer is licensed but there's a bit of a language barrier and I'm not certain he understands my question.
Thanks!
