What is a twist lock receptacle and purpose of use?

Moved from forum helps

Thanks for posting your homework here. The answer is obvious. Locks secure and require keys. The key here is the twist.

Isn't it so obvious when they post the question exactly as written? :p :rolleyes:

:DYep.

Remember, these teachers are teaching "what to think", "not how to think".

I'm trying to teach "How to think".

Good grades don't always come from learning, unfortunately. I know. I got a 3.8 GPA in high school, a 1.6 GPA and got kicked out of a University. I figured out what went wrong and got a 4.0 GPA at another university and went back and got a another degree with a 2.006 GPA at the 1.6 GPA school.

I learned to get good grades at the 4.0 GPA school. I took two classes as a ghost. I tested out of classes. Used radical memorization techniques.
I had an excellent mentor (Chairman) and we got really creative. I doubt, anybody went to class and the prof said, "If you have something better to do, don't bother coming to class."
