Question 234Electricity & Electronics - Assistant Engineer

The correct answer is D) 18 AWG. According to 46 CFR Subchapter J, regulations prohibit the use of portable electric cord or fixture wire aboard ship if that wire or cord is smaller than 18 AWG. This is to ensure the wiring used on ships is of sufficient size to safely carry the electrical load and prevent potential fire hazards. The other answer choices, 12 AWG, 14 AWG, and 16 AWG, are incorrect because they represent larger wire sizes that would be allowed under the regulations. Smaller wire sizes are prohibited to maintain electrical safety standards on vessels.
