🔍 Key Concepts

• Electrical isolation vs. control/protection functions • How a bus and generator circuit breaker are physically connected on a shipboard switchboard • Difference between a protective relay (reverse power/reverse current) and a mechanical disconnect/link/fuse

💭 Think About

• Which device in the options actually creates a visible, physical break in the power path between the generator breaker and the bus? • Which devices are meant mainly for protection and automatic tripping, not for safely working on the breaker itself? • On a marine switchboard, what is the normal, safe procedure before working on bus or breaker gear: do you rely on a relay, or do you open and/or remove solid conductors like links or fuses?

✅ Before You Answer

• Verify which option represents a primary current‑carrying path rather than a sensing/control device. • Check which device would remain safe if someone accidentally re-energized the generator while you were working. • Confirm which choice gives you a clear isolation point you could lock and tag out before maintenance.
