Is there a legal technique to add a neutral to a 240 volt delta three phase transformer? (480 v delta Primary, 240v delta secondary)
The present transformer has no center tap between two power legs to derive 120 volts.
Is it possible to add an "outboard" single phase transformer (or two transformers in series) to create this center tap for 120 volt loads?
To be consistent with present practices, this center tap would have to be grounded as well.
Is this possible? workable? legal?
