🔍 Key Concepts

• Short-time rating for motors used on deck machinery such as winches • Where to find motor duty and rating requirements in 46 CFR Subchapter J – Electrical Engineering • Difference between continuous duty motors and short-time duty motors

💭 Think About

• Ask yourself: For a winch that runs only during cargo or mooring operations, does the regulation require the motor to run continuously, or just for a specific minimum period at full load? • Look at the answer choices: which ones are regulation references and which actually state a time in hours that could be a short‑time rating? • Think about what "short‑time" means on a nameplate: is it usually given in minutes or hours, and what is the common standardized value for deck machinery?

✅ Before You Answer

• Confirm in 46 CFR Part 111 (Electrical Systems – General Requirements) where it talks about motors for deck winches or deck machinery and see what minimum short‑time rating is specified. • Make sure the option you choose actually answers the question in hours, not just giving a CFR section number or a mixed load cycle description. • Verify that the selected choice matches a single, clear short‑time period at full load, as required for an electro‑mechanically driven deck winch motor.
