Helloe every one,
I have a situation where an engineer have specified a step up transformer (9KVA)from 208V (single phase) to 480V/277V (single phase). I have looked at multiple manufacturers catalog and could not find any transformer with this specification. Does anyone know someone makes it? also, the contractor have submitted a step up transformer instead with 208V-to 277V, and the down stream panelboard is single phase. How can we wire the secondary of the transformer (277V) to a single phase panel with two busbars?
Any help will be appreciated.
