Question 1 of 27070

According to 46 CFR, Subchapter J (Electrical Engineering), what is another term for a motor enclosure which is considered to be waterproof?

🔍 Key Concepts

• 46 CFR Subchapter J – Electrical Engineering definitions for motor enclosures • The difference between watertight, drip-proof, splash/spray-resistant enclosures • How the Coast Guard uses the term waterproof for electrical equipment

💭 Think About

• Look at how each term would perform if the motor were exposed to heavy seas, hose streams, or immersion – which best matches "waterproof"? • Consider which terms are designed only to protect against vertical drips or light spray rather than full water exposure. • Think about how conservative marine electrical standards are: which enclosure type would be required where water contact is likely and safety is critical?

✅ Before You Answer

• Verify in 46 CFR Subchapter J how motor enclosure types are defined or referenced. • Check which option is intended to exclude water under specified test conditions, not just reduce the amount entering. • Confirm whether the term associated with "waterproof" implies protection from all directions, not just from above.
