Suppose it is desired to connect a dual voltage three phase squirrel cage induction motor for low volts, but it is undetermined whether the nine-lead motor is internally configured for wye or delta configuration. Using an ohmmeter, the motor itself with leads disconnected, and the illustration as a guide, what statement is true? EL-0134

Correct Answer: Option C — If leads "7", "8", and "9" have continuity across each other, the motor is "wye" configured. Without continuity, the motor is "delta" configured.

In a standard nine-lead dual-voltage motor, leads 7, 8, and 9 form the internal wye connection point. Continuity across these three leads confirms a wye configuration, whereas lack of continuity indicates a delta configuration.
