Question 392Electricity & Electronics - Assistant Engineer

The correct answer is B) The plug on the end of the cord that may be energized when unplugged from the receptacle must be female. According to 46 CFR Subchapter J (Electrical Engineering), any plug that may become energized when disconnected from a receptacle must be a female plug. This is to prevent accidental contact with live electrical parts, which could pose a serious safety hazard. The male plug, which is the energized part, must be the one that remains in the receptacle to avoid exposure. The other options are incorrect because A) would allow the male plug to be exposed, C) would expose both male plugs, and D) is not correct as the regulations do allow for transmitting power between receptacles, as long as the proper safety precautions are in place.
