🔍 Key Concepts

• 46 CFR Subchapter J requirements for portable electric tools and cables • Purpose of strain relief on cords (what problem it prevents) • Whether knotting/taping alone is considered an approved engineering control under Coast Guard electrical regulations

💭 Think About

• Ask yourself: Does the Coast Guard usually accept temporary-seeming measures like simple knots or tape as the only way to protect electrical connections? • Think about what happens at the terminal or plug if someone pulls hard on the cord—what method best keeps that pull from being transmitted to the electrical connection? • Consider whether regulations normally require a specific device or allow equivalent means that achieve the same protection.

✅ Before You Answer

• Check in 46 CFR Subchapter J if strain relief fittings are explicitly mentioned for portable cords and tools. • Verify whether knotting or taping by itself is listed as an acceptable method, or if it must be part of an engineered arrangement. • Confirm that the regulation does not place the tension requirement on the electrical joints/terminals themselves, but on a separate means to take the strain.
