Understanding the NEC

Extracted from Mike Holt's best selling book Understanding the National Electrical Code.

The National Electrical Code (NFPA Volume 70) has been published, edited, and revised since 1897 and has been sponsored by the National Fire Protection Association (NFPA) since 1911. The NEC is considered by some to be the finest building code standard of its kind. The NEC is used not only throughout most of the United States, but also in some other countries throughout the world, such as Mexico and Puerto Rico.

The original Electrical Code was developed by the combined efforts of the insurance, electrical, and architectural industries. The first electrical code was assembled by the National Association of Fire Engineers in 1897.
