Lead-acid batteries used aboard "T-Boats"...

🔍 Key Concepts

• 46 CFR Subchapter T requirements for electrical installations on small passenger vessels • Safety concerns with battery terminal connections on vessels (vibration, corrosion, arcing, and accidental disconnection) • Difference between permanent vs. temporary/spring clamp connections in a marine environment

💭 Think About

• On a moving vessel that can pound and vibrate, what kind of connection is least likely to loosen or spark? • Which type of terminal connection best prevents accidental disconnection if the battery box is jostled or the vessel heels over? • Think about what the Coast Guard would want during an emergency: do they want battery connections that can fall off, or ones that stay secure under all conditions?

✅ Before You Answer

• Verify which option describes a secure, non-loosening connection suitable for constant vibration • Eliminate any options that sound temporary, easily dislodged, or makeshift • Consider which answer best matches the idea of a fixed, mechanically secure connection that resists loosening over time
