🔍 Key Concepts

• How a dual-voltage split-phase motor is wired (series vs. parallel main windings) for high voltage vs. low voltage operation. • How to tell if a split‑phase motor is reversible by looking at which leads (main and auxiliary/start windings) are brought out to the terminal board. • Lead designations T1–T4 (main) and T5–T8 (auxiliary/start) and the standard NEMA connection patterns for 115/230‑volt motors.

💭 Think About

• Compare the connections between T1–T4 in figure A with the usual series (high‑voltage) and parallel (low‑voltage) patterns. Which one matches? • Look at how many motor leads are available at the terminal board and how they are arranged. Could you, in principle, swap the auxiliary (T5/T8) or one of the main windings to reverse rotation? • Ask yourself: does figure A show only fixed internal connections to L1 and L2, or does it show separate, identifiable leads that could be re-strapped for the opposite direction and/or different voltages?.

✅ Before You Answer

• Identify clearly whether T2 is tied to T3 only (series connection → typical of high-voltage), or whether T1 is tied to T3 and T2 to T4 (parallel connection → typical of low-voltage). • Count how many distinct leads from both the main and auxiliary windings reach the terminal area; if both sets can be independently reconnected, the motor is typically reversible. • Before choosing, verify whether the present strap pattern on T1–T4 could be quickly changed to the other voltage, confirming that it is indeed dual-voltage rather than single-voltage.
