ARTICLE 90 - INTRODUCTION

Sometimes Electrical Wiring in Utility Facilities Must be Installed in Accordance With the NEC.
Section 90-2(a)(5), Relocate FPN of Section 90-2(b)(5) into a Requirement

Proposal 1-10a Proposed By: Code Making Panel No. 1
Comment 1-11 Comment By: American Public Power Association

ARTICLE 100 - DEFINITIONS

New Definitions Have Been Added to the NEC

Bathroom (relocated): The term bathroom was added to the definitions in Article 100. A bathroom is an area including a basin with one or more of the following: a toilet, a tub, or a shower.
Proposal 1-38 Proposed By: Joseph J. Andrews

Energized (new): The term energized is used in almost 100 locations throughout the NEC and remained undefined. The term energized means to be electrically connected to a source of potential difference.
Proposal 1-58 Proposed By: Ray A. Jones

Luminaire (new): The term luminaire is a universal and international term which has been adopted by the Binational Harmonization Committee. The term Luminaire is defined as : A complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply.
Proposal 18-1 Proposed By: Bernard J. Mezger

Nonlinear Load (new): In the previous Code, nonlinear loads were referenced as electronic equipment and electric discharge lighting. The term for these types of loads is called Nonlinear Load - A nonlinear load is a load where the wave shape of the steady state current does not follow the wave shape of the applied voltage.

Nonlinear Load - New Fine Print Note. A Fine Print Note was added to the definition of nonlinear load to clarify that the NEC does not determine when a load becomes nonlinear, nor does it establish thresholds of nonlinearity. The purpose of the new FPN is to help identify that electronic equipment, electronic/electric discharge lighting, adjustable drive speed systems, and similar equipment may be nonlinear loads.
Proposal 1-84 Proposed By: Nonlinear Load Committee

Service Conductors (revised): The definition for service conductor in Section 230-10 was deleted and the definition located in Article 100 was revised to include other source of power to the service disconnecting means. The intent of the change was to recognize that service conductors can originate from an on-premises source of power such as a generator.

CHAPTER 9 - TABLES AND EXAMPLES

Chapter 9 Tables have been Modified, Deleted, and Relocated.
TABLE 1 Note 1. Revisions were made to Note 1 of Table 1 to indicate that the number of conductors in a raceway (formally Tables 3A, 3B, and 3C) have been relocated and expanded to the new Appendix C. TABLES 3A, 3B, and 3C.
Tables 3A, 3B, and 3C in the 1993 NEC (three pages) which contained the maximum number of conductors for a raceway, have been expanded and relocated to a new Appendix C (72 pages). Proposals to recognize the difference in the internal diameter of conduit and tubing were accepted. The result was the development of thirteen tables that contain the maximum number of conductors and fixture wires permitted for a specific type of conduit or tubing; such as, flexible metal, rigid metal, and rigid nonmetallic conduit based on maximum percent fill as listed in Table 1 of Chapter 9.
Table C1 - Electrical Metallic Tubing.
Table C2 - Electrical Nonmetallic Tubing.
Table C3 - Flexible Metal Conduit.
Table C4 - Intermediate Metal Conduit.
Table C5 - Liquidtight Flexible Nonmetallic Conduit (gray type).
Table C6 - Liquidtight Flexible Nonmetallic Conduit (orange type).
Note: Appendix C, does not have a table for Liquidtight Flexible Nonmetallic conduit of the "black" type.
Table C7 - Liquidtight Flexible Metallic Conduit.
Table C8 - Rigid Metal Conduit.
Table C9 - Rigid PVC Conduit Schedule 80.
