According to 46 CFR, Subchapter J (Electrical engineering), regulations prohibit the use of portable electric cord or fixture wire aboard ship if that wire or cord is smaller than what size?
• 46 CFR Subchapter J – Electrical Engineering requirements for shipboard wiring • Minimum conductor size rules for portable cords and fixture wires • Difference between common household wire sizes and marine regulatory minimums
• Look up the specific section in 46 CFR Subchapter J that deals with portable cables and cords—what minimum American Wire Gauge (AWG) size is explicitly stated? • Compare the listed AWG sizes: which sizes are typically considered too small (too light) for robust shipboard service due to current-carrying capacity and mechanical strength? • Think about safety margins at sea: would the Coast Guard likely allow the thinnest sizes listed, or require something a bit heavier for durability and fire safety?
• Verify in 46 CFR Subchapter J the exact AWG number named as the minimum size for portable cord or fixture wire • Confirm that the AWG scale is inverse (larger AWG number = smaller wire diameter) before judging which option is ‘smaller’ • Make sure you distinguish between rules for permanent wiring and those for portable cords/fixture wires, since their minimum sizes may not be the same
