Each secondary winding of a transformer delivering 120/208 volts on its secondary supplies 120 volts.

Explanation:
In a 120/208 V transformer with a wye (star) secondary, each winding provides 120 V from a line to neutral. The 208 V is the voltage between any two lines, which is √3 times the line-to-neutral voltage: 120 × √3 ≈ 208 V. So the voltage that each individual secondary winding supplies is 120 V, while the 208 V comes from measuring between two different windings.
