Q

One of your ship's indirect-drive steering gear drive motors needs to be replaced. In accordance with 46 CFR Subchapter J, what minimum short-time rating should the replacement motor have in hours?

🔍 Key Concepts

• 46 CFR Subchapter J requirements for steering gear power units and motors • Definition of short-time rating for electric motors • Differences between short-time rating and continuous duty rating

💭 Think About

• Look up the specific 46 CFR section that addresses steering gear drive motor ratings and note the exact minimum time specified. • Think about why the Coast Guard requires a certain short-time rating for steering gear motors—what scenario are they trying to ensure the motor can safely handle? • Compare each answer choice to the regulatory language: which one matches the wording and intent of the rule, rather than sounding like a general motor spec?

✅ Before You Answer

• Verify the exact CFR citation in Subchapter J that covers steering gear drive motors (hint: electrical engineering requirements for steering gear). • Confirm the formal definition of short-time rating and how it is expressed (time at rated load, not mixed-load conditions). • Make sure the option you choose describes only a short-time rating in hours at full load, not a combination of continuous and short-time operation.
