I'm getting a lot from this. I'll admit that I drank some coffee first. ;-) Joking aside it's Obviously so important, but as you said in Part 1, for most of us under edumakated it's usually an after thought. :-D Thank you for taking the time and energy to share this. Props and Respect.
I do have a novice question for you if you see this... Does N-G mean neutral to ground? That seems to be the only logical interpretation, but I hate guessing at important stuff.
Thanks,
Pete
