🔍 Key Concepts

• Paralleling generators/alternators on a main bus • How load sharing works between units in parallel • What happens if you open a breaker while a unit is still carrying load

💭 Think About

• Before taking an alternator offline, what condition should its load be in compared with the other unit? • If you open the circuit breaker while the alternator is still supplying current, what mechanical and electrical effects could occur? • Which action directly changes how much current (kW) the outgoing alternator is contributing to the bus?

✅ Before You Answer

• Verify which step directly reduces the alternator’s load before disconnection • Check which option is about breaker operation versus load adjustment • Confirm the safe sequence used on ships: match/synchronize → share load → remove load → open breaker → adjust as needed
