Ground

[wireguy8169]

Ok going to sound like a idiot :grin:

but on a test for the NEC 2008 there is a question that ask's "An intentional or accidental grounding connection between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of earth"

gives four answers short, fault, overload, none of the above. I did know it was none of the above but for the life of me I could not find this definition in the NEC for a ground that matches this. Can someone point me to this. I looked in 100...maybe its not an exact match. Mainly I wanted to ask due to the questions ask for the NEC reference.

Thanks

This is close, from 250.2;

Ground Fault. An unintentional, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non?current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment, or earth.

If you look in your '05 code book you'll find it, but not in '08.

The article 100 definition of "Ground" would / should be the answer.

Ground. A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth or to some conducting body that serves in place of the earth.

Dave, you are correct, I should have mentioned that in my post above.

did not even think to look in 05 code, just did and sure enough. The exam was my final for the 45 hour 2008 code course. I did see several errors in the book during the course mainly code references, maybe they just took the questions from their 2005 version of the book. Again, ground was not in the answers so obviously it was NoA. Just wanted to make sure I wasnt going crazy, wonder why they removed that definition.

wonder why they removed that definition.

To make room for the rather amusing new one.
