What is the purpose of tying the neutral leads together in a wye configuration?

• A. To form the neutral point for a balanced star connection.
• B. To connect to ground.
• C. To supply to high-voltage lines.
• D. To reduce winding resistance.

Answer: (A)

In a wye (star) connection, the three winding ends are joined to form a single point called the neutral. Tying those neutrals together establishes this neutral point, which serves as a stable reference for the line-to-neutral voltages and provides a return path for current, especially when loads on the phases are unbalanced. This setup also enables using single-phase equipment connected between any line and neutral. Grounding the neutral is a separate safety step that may be done at one point in the system, but the act of tying the windings together is specifically to create the neutral point for a balanced star configuration.
