Multi-wire Circuits

220/221

I'd say not MWBC. It's two legs of the SAME circuit.

On a switched outlet there is no voltage between the ungrounded conductors...right?

Celtic

What would be the point in running a 3-wire from a panel and NOT utilize 2 conductors for 2 different circuits?


Where are you heading?

I thought I was clear?????

If you were clear, would I be asking for clarification?

No you haven't....what has MWBC got to do with a switched outlet?

The code book is something you use as a reference, It was not ment to be used as a study guide.

Celtic.

I was quoting Mark and explaining why a 3 wire to a switched outlet was not a MWBC.

I don't know why it was so hard to understand but I hope it's all good and we can sleep well tonight.

Actually it's a great study guide if you are taking an exam to get an electricians license, all the questions come from it. It's also packed with all types of electrical mumbo jumbo and some of the code books have nice pictures.

The first day of code review, we had from 25, to 30 students, half of them trying to pass the code section on the state exams. I would ask them, how they prepared for the test, a number of them would say, they studied the code, then I would ask how they did, they din't do well, some have taken the code test as many as 4, or more times. the students that used it as a reference book, had a much better pass rate. It may be you have more accurate information on the subject of study skills and pass fail rates.

I'm not sure what you're saying, if you are taking a test on the code, I think studying and knowing the code would be a great way to pass the exam. Not only do you need to know the code, you need to be able to locate what you're looking for relatively quickly, that's where the studying helps. What exactly do you mean when you say use it as a "reference book"?

The state code section exams. are open book exams, you refer to the book, there is no need to waste time, trying to but it to memory. A good understanding of the chapters, and sections will allow you to index to the material, putting any book to menory will not increase success, in recall of the content. After we get the students to learn how to search by sections, they have a much beter success rate at passing the exams.

mickeyco

And you get that how?

Just remember how you learned to use an index in school, simply apply the same methods, you sure don't learn if from studing the content.

That's how it is here.

I passed mine on the first shot and I never even owned a code book

fridaymean

Not all of them are open book here. There is no state test, but one AHJ that does testing, does it closed book.

JohnJ0906

That is absolutely ridiculous.

I know my memory is not perfect, so I refer to my NEC all the time.

I think the point of the test, among other things, is to demonstrate that a person knows how to use the code book, not how good his memory is. We should be ENCOURAGED to pick up the book and check.

I have read this forum on Multi-Wired Circuits. It is my expressed opinion that Northerboy & Thom are correct in their assesment of the topic.
