No paper trail on this transformer but i was told that it is a spare for the current 1500kVA 4160/480V delta delta corner grounded secondary system that we have. Anybody know what do the switch positions on the picture #2 represent. Notice barely readable nameplate calling this 480Y/277 but CX1, BX2 and AX3 labeled blue white and red as the standard labeling we use for the current system.
As always your time and input is very appreciated.
Sincerely
Amel
