🔍 Key Concepts

• Location in 46 CFR that covers watertight door power units and motors • Meaning of a motor short-time rating in hours for intermittent-service equipment • How long watertight doors are expected to be able to operate safely under emergency conditions

💭 Think About

• Which option best matches the minimum operating period the regulations expect for power-operated watertight doors in an emergency? • Is the required rating very brief (a few minutes), moderate, or long enough to cover a typical emergency response period? • Think about whether regulations usually choose extremely short times, or a more conservative duration, for life‑safety critical equipment.

✅ Before You Answer

• Look up the specific section in 46 CFR, Subchapter J or Subchapter S, that deals with watertight doors and their power sources • Confirm the exact wording about minimum short‑time rating for motors driving watertight doors • Make sure the selected time is sufficient for multiple open/close cycles during an emergency, not just a single quick operation
