Which option correctly indicates the lead numbering and winding connections for a motor?

The correct answer is based on the specific details concerning the lead numbering and winding connections for the motor in question. The option correctly indicates the standard or common configuration as defined in technical resources, where the second reference (II) aligns with the established guidelines for motor wiring and lead connections.

In electrical engineering, particularly in motor controls and installations, following standard lead configurations is crucial for ensuring proper operation. Incorrectly wiring a motor can lead to operational failures, inefficiencies, or even safety hazards. Therefore, option II likely corresponds to manufacturer specifications or industry standards that dictate how the leads should be numbered and connected, allowing for proper direction of rotation and compatibility with control systems.

Understanding these conventions is essential for electricians and contractors, as it helps ensure that installations are performed safely and effectively. Familiarity with lead configurations also aids in troubleshooting and maintenance of electrical systems.
