This is a good example of the difference between the language of our profession, as used in the NEC, and what I like to call, "conversational English." In the first language, the terms "receptacle" and "outlet" are clearly defined, the one being a physical device and the other being essentially the location at which the first is installed. In the second language, the two terms are interchangeable, at least in the minds of your common citizen. If you try to explain to a homeowner that the box to which a ceiling light fixture or a smoke alarm is technically an "outlet," you may well get a blank stare.
