Significant Proposals for 2005 NEC Part I
As Reviewed by Mike Holt
Articles 90 through
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
Article 90 Introduction
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
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.
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
Bonding Jumper, System. New term added for use with separately derived systems, see
250.28 and 250.30.
Coordination (Selective). Definition was relocated to Article 100 from 240.2, because
it is used in more than one article.
Grounded, Solidly. Term was contained in 230.95, but it was relocated to Article 100
because it is in more than one article.
Grounding Electrode. New term added because it is used in more than one article.
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.
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.
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."
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)].
Qualified Person. FPN added to the definition to give examples of the type of safety
training required for a person to be considered qualified.
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.
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."
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
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]
