🔍 Key Concepts

• Ship’s service switchboard and how power sources are connected to the main bus • Why paralleling ship’s generators with shore power can be dangerous if done improperly • Normal sequence for transferring load from ship’s generators to shore power or vice versa

💭 Think About

• Think about whether a vessel’s generators and shore power are normally on the same bus at the same time, or if one source is removed before the other is connected • Ask yourself what the main purpose of the shore power breaker is: to connect shore power to the bus, or to allow paralleling with ship’s generators? • Consider what would prevent back‑feeding power into the pier or into another generator source

✅ Before You Answer

• Verify whether standard practice is to parallel ship’s generators with shore power, or to avoid paralleling them • Confirm what must happen to the ship’s generators relative to the main bus before shore power is safely connected • Check which options describe a normal, safe operating condition vs. a special or unlikely situation (e.g., only in a shipyard)
