Question 1 of 27070

According to 46 CFR, Subchapter J (Electrical Engineering) regulations, receptacle outlets at or above what voltage are required to have grounding poles?

🔍 Key Concepts

• 46 CFR Subchapter J – Electrical Engineering general requirements for shipboard wiring and equipment • Specific section in 46 CFR Part 111 that addresses receptacles (outlets) and when they must be of the grounding type • Difference between low-voltage control circuits and higher-voltage power circuits on vessels

💭 Think About

• Look up the section in 46 CFR that specifically mentions receptacle outlets and read the sentence that talks about when a grounding pole is required. • Compare the listed voltages in the choices with the regulatory wording – does the rule say "at or above" a certain voltage to ground, or does it focus on only very high-voltage systems? • Think about typical shipboard practice: which voltage level usually starts to present a significant shock hazard that regulations treat differently from extra‑low‑voltage systems?

✅ Before You Answer

• Confirm you are reading within 46 CFR Subchapter J, Part 111 (Electrical Systems—General Requirements). • Verify the exact voltage threshold in the text that says receptacles "must be of the grounding type" or "must have a grounding pole." • Make sure you distinguish between voltage to ground and total circuit voltage if the regulation uses that wording.
