Standards Reference Guide

National Electrical Code (NEC**) Catalog Reference Information

The National Electrical Code is a set of guidelines describing procedures which minimize the hazards
of electrical shock, fires, and explosions caused by electrical installation.        The text of the NEC is
contained in nine chapters, each chapter broken into individual articles.

NEC types are acronyms consisting of a prefix decribing cable type (e.g. coax, CATV, fiber optic) and
a suffix indicating the type of flame test it has passed and where it can be installed.          Articles
describing wire and cable products - including required cable markings - are listed in the chart to the
right.
