What terminal is created when a stator is connected in a wye configuration and the three ends are joined?

• A. The neutral
• B. The ground
• C. The center tap
• D. The star point

Answer: (A)

When three windings are connected in a wye and the ends of all three are tied together, a single common point forms. This point is the neutral, also known as the star point. It serves as the reference for the three phase voltages and can be grounded to provide a safe return path and a fault current path if needed. The term star point is essentially another name for the same junction. A center tap is something different, typically a midpoint of a winding used in other configurations, not the node created by tying all three windings together. Ground is a separate earth reference and isn’t automatically created just by joining the windings; grounding the neutral is an intentional safety choice.
