We generally don't 'just answer' homework questions here.

But we will try to help you find the answer for yourself. This means you need to put forth some effort.

"How and why" means your answer is based on this code reference, or this calculation, etc.

The most consistant lesson about using the Code is looking it up. The only way you learn is from doing it.

Once found, then the work of understanding it occurs next.

This exercise never ends.

Might as well continue looking now.

ok, I'll give a hint.















your answers are in the 1st 1/2 of the code book.

Tonka, you'll find the answer to #1 in Art's 220 and then 310, and to #2 in Art 210.

Answers to both questions can be found in 210. Read all of parts II and III. (2005)

The reason for these types of questions is for you to read the NEC, and learn to find answers. It is not about memorizing the NEC, but rather, learning to navigate the NEC. Keep up the work, keep asking questions, you can learn just as the rest of us are.
