Significant Proposals for 2005 NEC Part I

As Reviewed by Mike Holt

Articles 90 through 100

The following text is a quick summary of the proposed changes for the 2005 NEC. This document is a work in progress and the Code panel will change many over the next few months. Some of these you might find important to your work and you might want to follow their progress with me. Therefore, each week I will email you a few of these changes.

Each proposed change has a Report on Proposal (ROP) number, like 1-25. This number reflects the Proposal Number and all action on this proposal can be viewed in the following PDF PDF document NECPart1 [4.72 MB].

As always, I am looking to improve our products, so if you feel you have anything to contribute, please let me know at Mike@MikeHolt.com.


Article 90 Introduction

1-25
a - A 90.2 Scope
(B) Not Covered. New FPN intended to help clarify the type of organizations that may be exempt from the NEC.


Chapter 1 General

Article 100 Definitions

1-46
Abandoned Cables. The definition for abandoned cables was relocated from Articles 645, 725, 760, 770, 800 and 820 830 to Article 100 because this term is used in more than one article.

1-49
Air duct. New term added for use in Articles 725, 760, 770, 800 and 820. The definition was taken from NFPA 90A - Standard for Installation of Air conditioning and Ventilating Systems.

1-63
Bonding Jumper, System. New term added for use with separately derived systems, see 250.28 and 250.30.

1-76
Coordination (Selective). Definition was relocated to Article 100 from 240.2, because it is used in more than one article.

1-136
Grounded, Solidly. Term was contained in 230.95, but it was relocated to Article 100 because it is in more than one article.

1-97
Grounding Electrode. New term added because it is used in more than one article.

1-98
Grounding Electrode Conductor. The definition was reworded to clarify that it applies at a building supplied by a feeder or branch circuit in accordance with 250.32.

1-101
Guest Room. New term added because it is used in more than one article. This definition came from NFPA 101 - Life Safety Code to provide consistency between codes.

1-101
Guest Suite. Many lodging facilities contain a "suite" and this term provides guidance to the Code users as to which NEC requirements apply to "guest suites."

1-114
Kitchen. The term "kitchen" is in common use and is well understood in residential dwelling units, but it's so clear in industrial and commercial areas. This definition is an effort to fine the areas in commercial installations where GFCI protection is required for 15A and 20A, 125V receptacles [210.8(B)(2)].

1-130
Qualified Person. FPN added to the definition to give examples of the type of safety training required for a person to be considered qualified.

1-132
Separately Derived System. Deleted the list of electrical energy sources from the definition, so that there is no need to add new energy sources, such as fuel cells.

1-138
Supplementary Overcurrent Protective Device. New term added because it is used in more than one article. The new definition clarifies that there is a difference between a "supplementary overcurrent protective device" and a "general use overcurrent protective device."

Author's Comment: " Supplementary overcurrent protective devices are application oriented and prior to applying the devices, the differences and limitations for these devices must be investigated. Supplementary overcurrent protective devices do not have standard overload characteristics and may differ from the standard branch circuit overload characteristics."

In addition, supplementary overcurrent protective devices have interrupting ratings that can range from 32 amps to 100,000 amps. It is important to be sure that the device's interrupting rating equals or exceeds the available short-circuit current and that the device has the proper voltage rating for the installation [110.9 and 110.10]
