Which of the following actions should be taken to minimize shock hazard of an Inmarsat terminal?

🔍 Key Concepts

• Shock hazard prevention in marine electronics installations • The purpose of electrical grounding/bonding on shipboard equipment • Difference between insulation and grounding for safety

💭 Think About

• Think about what happens if a live wire inside the Inmarsat terminal comes loose and touches the metal case—what arrangement will cause a protective device (like a fuse or breaker) to operate quickly? • Which option would make it more likely that a person touching the equipment becomes the easiest path to ground—and which option would instead provide a safe, low-resistance path? • Consider standard marine practice: how are other metal-cased electronic devices normally treated to reduce shock risk on board?

✅ Before You Answer

• Identify which choice provides a low-impedance path for fault currents away from personnel. • Eliminate any option that would isolate metalwork in a way that could let it float at dangerous voltages. • Check which option aligns with normal practice of bonding exposed conductive parts to ship’s grounding system.

Which of the following actions should be taken to minimize shock hazard of an Inmarsat terminal?

Ensure the DC power supply is insulated from the ship's hull.

Ensure the chassis of the Inmarsat terminal is connected to an electrical ground.

Install a common busbar for grounding to ensure common-mode coupling.

Isolate the transceiver's metal frame to avoid a return path for fault currents.
