In a Low Voltage Delta AC Motor configuration, each lead corresponds to a specific terminal that must be interconnected to complete the circuit. The leads from the power supply (L1, L2, L3) represent the three phases of the motor, while the terminal leads (T1, T2, T3, T4, T5, T6, T7, T8, T9) connect to different parts of the motor windings.

The operation of a Delta connection involves connecting the terminals of the motor in such a way that each phase winding is connected end-to-end, forming a triangular loop. Thus, in the Delta configuration, the leads must be spliced together specifically as follows:

  • L1 connects to T1 and T6

  • L2 connects to T2 and T4

  • L3 connects to T3 and T5

Since the question indicates splicing leads together, indicating that all sets of connections (for L1, L2, and L3 with their respective terminals) are included, the answer encompasses all combinations of connections for each phase lead.

This comprehensive connection setup is necessary to ensure the proper functionality of the motor, allowing it to operate efficiently and effectively within its rated specifications. Therefore, indicating
