In a subtractive polarity transformer, the x1 bushing is located on which side?

Explanation:
In subtractive polarity, the winding ends are oriented so that the starting end of the secondary (X1) sits on a fixed side for quick identification. The X1 bushing is placed on the left side when you view the transformer from its standard front orientation, with X2 on the right. This arrangement helps ensure the voltages subtract when measured or connected in the expected way, which is why X1 is on the left. The other sides (top, bottom, or right) aren’t the designated position for this polarity convention.
