If you guys really want to revisit Al's outlet theory I will request you start a new thread to do so and not clutter up this threads topic.
That's a good idea, Bob.
GoldDigger, about 10 years ago the Forum entertained this discussion at length. Clicking
here will take you to my summary of the topic from then. That post is long, and is near the end of a thread that got into the upper-700s. The applicable NEC language has not changed from then to now, so it is still relevant. Additionally, some new Code and product developments have added support to "my theory", in my opinion.
Let me know if you, or someone else, want to explore this further in another thread and I'll come join you. I don't regularly check for new threads, so I might miss the starting of one tied to this thread.
To me, the real value of this lies in the understanding each one holds of what "Outlet" is.
