🔍 Key Concepts

• 46 CFR Subchapter J requirements for motor controllers and low-voltage protection vs low-voltage release • Differences between vital propulsion auxiliaries and non‑vital auxiliaries • Safety concern of automatic restart after power loss and when it is considered hazardous

💭 Think About

• Ask yourself: In which situation would it be especially dangerous if a motor automatically restarted after a temporary loss of power? • Which CFR requirement tries to ensure that, after a voltage dip or blackout, the operator must manually restart the motor instead of it coming on by itself? • Look at which options describe conditions where automatic restart is hazardous versus where it is acceptable or the equipment is non‑vital.

✅ Before You Answer

• Verify in 46 CFR Subchapter J how low‑voltage release is defined and how it behaves after a power interruption. • Check which types of motors (vital vs non‑vital, hazardous vs non‑hazardous automatic restart) are explicitly associated with low‑voltage release in the regulation text. • Confirm whether motors with restart capability at a central control station are treated differently from those without restart capability regarding low‑voltage release or protection.
