Introduction To The Code Book Flashcards
The National Fire Protection Association is has acted as sponsor of the what.
NATIONAL ELECTRICAL CODE since 1911 (NFPA)
The original Code document was developed in what year
1897 as a result of the United efforts of various Insurence, electrical, architectural, and allied interests.
This Code is purely advisory as far as NFPA is concerned. It is made available for a wide variety of both public and private uses in the interest of life and property protection. for what purposes are they used for?
These include both use in law and for regulatory purposes, and use in private self-regulation and standardization activities such as insurance underwriting, building and facilities construction and management, and product testing and certification.

CHAPTER ARTICLE PART SECTION SUBSECTION EXCEPTION TABLES INFORMATIONAL NOTES
CHAPTER:
There are nine chapters in the NEC. Chapter 2, Wiring and Protection, is one of the nine chapters
ARTICLE:
The first number of an Article denotes the Chapter that it’s in, i.e., Article 250 – Grounding and Bonding. Article 250 is in Chapter 2.
PART:
A Part divides an Article into two or more simpler topics. Not all articles have Parts or subheadings. Parts are identified by a roman numeral. Article 250 contains 10 Parts, one of which is Part III. Grounding Electrode System and Grounding Electrode Conductor. PAGES 70-2 and 70-117.
SECTION:
A Section is identified by a numbers only, i.e., 90.1, 90.2, 250.20, or Section 250.52 Grounding Electrodes. (PAGE 70-117)
SUBSECTION:
A Subsection is identified by a capital letter or number in parenthesis, i.e., Subsection (A) Electrodes Permitted for Grounding and Subsection (1) Metal Underground Water Pipe. (PAGE 70-117)
EXCEPTION:
Exceptions apply to the preceding rule only unless otherwise noted, as in exceptions no.1, no. 2 and no. 3 to Section 250.110(1) through (6). (PAGE 70-126)
Exceptions
are italicized and multiple exceptions are numbered. Example: there is an exception to Section 250.50. (PAGE 70-117)
TABLES:
Tables provide information such as conductor sizes, adjustment factors, ampacities, etc. There are several Tables in Article 250. One is Table 250.66 – Grounding Electrode Conductor for Alternating-Current Systems. Section 250-66 describes the application of this Table. (PAGES 70-120/121)
