Sorry to answer these out of order....

5) Open core,Closed core,Shell core.Reference...sorry,it's from an electrical exam preparation guide I have with no cover:( Someone copied it for me in a loose leave binder a few years ago.

1)Higher.In doing so,any weaknesses will be revealed at a higher percentage than if the same voltage was used.Same reference.


2)NEC 2005 110.19


4)I'm in NEC 2005......408.34 through 408.36. Looks like ther are some CHANGES in this from when I found the EXCACT question in the book I mentioned in the first 2 questions.

3)NEC 2005......470.18(b)

Dilydaler,
These are questions I had on a state test a few days ago. This state does not allow for the use of a code or anything during the test. Thanks for the great answers. I don't know how they would think anyone would know these answers withou the NEC. My last question is how far upward does a class 1 Div 2 area go?
Thnaks again
Craig

How would someone take a Code Exam, without using the Code Book?
That would be a heck of a lot of information to memorize.

I thought the main purpose of the Code Exam is to verify the Examee can accurately navigate the Code Book, not how much Short-Term Memory Capacity the Examee possesses or lacks!

Maybe I am missing something here - sure looks that way!

I would understand not allowing the use of textbooks / manuals for the Theory questions on the Exam - those wouldn't be in the NEC.
The Examee needs to know the basic formulas, and the Mathematics to apply with the formulas.

What State are you taking the Exam in?

I am not flaming the OP, just kind of baffled.
