transformer 100v input tap

traw · 17th August 2007, 02:55 PM

Have a large (1.2kva) transformer with dual primaries, 3 lines each. 120-100-0. Do you just leave the 100v hanging? Is it there for other parts of world where voltage closer to 100?

Japan has a typical AC voltage of 100 VAC.

Leave the 100V tap open, insulated to prevent shorts of course.
