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 |
A) If leads "7", "8", and "9" have continuity across each other, the motor is "delta" configured. Without continuity, the motor is "wye" connected. |
B) If leads "4", "5", and "6" have continuity across each other, the motor is "delta" configured. Without continuity, the motor must be "wye" connected. |
C) If leads "7", "8", and "9" have continuity across each other, the motor is "wye" configured. Without continuity, the motor is "delta" configured. |
D) If leads "4", "5", and "6" have continuity across each other, the motor is "wye" configured. Without continuity, the motor must be "delta" connected. |
