🔍 Key Concepts

• Emergency generator requirements under SOLAS – especially separation from main power systems • Difference between synchronizing equipment (used when paralleling is allowed) and interlocking/safety devices (used to prevent paralleling) • Basic function of reverse current protection vs. mechanical/electrical interlocks

💭 Think About

• Ask yourself: Is the emergency generator supposed to ever run in parallel with the ship’s service generators, or must it always be able to supply power independently if the main system fails? • Which listed device is normally used only when two generators ARE intended to be paralleled (to match voltage, frequency, and phase)? • Which device(s) are designed to make it mechanically or electrically impossible to close the breaker in an unsafe or prohibited condition?

✅ Before You Answer

• Verify which option is a protective/safety interlock whose job is to prevent a breaker from closing under forbidden conditions, not just trip afterward. • Check which device is typically used for synchronizing generators that are meant to share load – that one is unlikely to be the correct choice here. • Confirm that the emergency generator is required to have independent starting and supply, and consider what design feature ensures its breaker cannot be accidentally paralleled with the main switchboard.
