Question: To reverse the direction of a standard 3-phase induction motor, an electrician must:
Answer options: ✅ Swap any two of the three line-voltage leads.
- Reverse the polarity of the single-phase control circuit.
- Change the overload settings.
- Swap all three line-voltage leads.
Correct answer: Swap any two of the three line-voltage leads.
