The purpose of the NEC is to make electricity as safe as possible for everyone. Now I have been around awhile and I think that as time goes by we continue to make definitions more and more complex. At least years ago most people could somewhat grasp the terms HOT, NEUTRAL and GROUND. I know they do not fall into the category of being scientifically correct but.
Now we have to confuse a lot of consumers and many electricians with terms like UNGROUNDED, GROUNDED, and GROUNDING. This is odd because most of the time they have nothing to do with the ground! It is usually about the source of the energy. Why can't we use terms like SOURCE, RETURN, and FAULT? Wouldn't this make it easier to understand for all involved?
There now I feel better. Have a good one.
