🔍 Key Concepts

• Relationship between the common equipment grounding conductor and the generator/transformer source windings in a 3‑phase, 3‑wire system • Difference between a solidly grounded system (neutral bonded to hull) and an ungrounded/insulated system • Typical practice on merchant vessel shipboard distribution systems (3‑phase, 3‑wire vs 4‑wire)

💭 Think About

• Look closely at figure A: is any point of the three‑phase source actually connected to hull ground or to the common equipment grounding conductor? • Compare what you see in figure A with figure B: which one shows the neutral or a winding point bonded to hull, and which one leaves the source isolated from hull? • Think about standard shipboard power: do most merchant vessels use a solidly grounded neutral, or an ungrounded/insulated system with insulation monitoring?

✅ Before You Answer

• Verify whether the neutral or any phase of the source in figure A is shown bonded to hull ground. • Confirm if the common equipment grounding conductor in figure A only ties equipment frames to hull, or also connects back into the source windings/neutral. • Decide which description (solidly grounded vs insulated from source) matches figure A, then match that with what is most common vs least common on merchant vessels.
