🔍 Key Concepts

• Three-phase AC power systems and what "phase sequence" means • Conditions required for safely paralleling AC generators (alternators) • Difference between AC three-phase equipment and DC systems

💭 Think About

• Which of these choices involves two or more AC power sources that must work together without causing large circulating currents or torque issues? • For which operation is the order of the phases (A-B-C vs A-C-B) critical to ensure rotation direction and proper load sharing? • Which options clearly do NOT depend on phase rotation or phase sequence to function normally?

✅ Before You Answer

• Identify which options involve three-phase AC rather than single-phase or DC • Ask: in which situation could an incorrect phase sequence cause motors to run backwards or generators to fight each other? • Eliminate any answer that deals purely with DC equipment or with small branch circuits where phase rotation is not normally checked
