I have a 277/480Y service in this building and need 230 volt 3 phase for a piece of equipment. Can I use an existing transformer that is a 480 delta 3 wire step down to a 120/240 delta 4 wire and just don't use the supplied neutral on the secondary. Or should I buy a new transformer that's 277/480 to 120/240 3 phase?
