Why can't a 9-lead motor be reconfigured from wye to delta?

• A. The windings can be reconfigured internally for high voltage, enabling delta connections.
• B. It requires a transformer to change between configurations.
• C. Internal connections are fixed for one configuration; leads are brought out for voltage selection, not configuration change.
• D. A 9-lead motor actually has separate windings that can be reconfigured with a jumper set.

Answer: (C)
