Chapter One
General
Article 100-Definitions
The National Electrical Code (NEC) contains a great number of
definitions. These are very important in interpreting the Code. If
you have any doubt as to the exact meaning of a word, it is wise to
refer to Article 100 and verify that meaning. You will also find that
the definitions in this section are arranged in two categories-"General"
and "Over 600 Volts."
As you continue through the Code, you will find additional definitions
scattered throughout other articles. These definitions are
very specific to that article and are therefore included with that article
and not in Article 100.
The following figures are useful in understanding the definitions.
For a branch circuit, see Figure 100-1. For a multiwire branch circuit,
see Figure 100-2. For an illustration of service drop, see Figure
100-3. Service-lateral and service-entrance equipment are illustrated
in Figures 100-4 and 100-5, respectively.
