Thanks Guys. Here is a more comprehensive list of significant proposals:
2008 Significant Proposals
Proposal 1-19
Article 100
This proposal will move the definition of ?bundled? from Article 520 to Article 100. Per Section 2.2.2.1 Article 100 of the NEC style manual, "In general, Article 100 shall contain definitions of terms that appear in two or more other articles of the NEC. There are at least three uses of the term "bundled" in the NEC. Section 310.15(B)(2), 334.80, and 520.53(H)(2). This will add clarity to the NEC at large.
Proposal 1-20
Article 100
This proposal adds a definition of clothes closet to Article 100. ?A small room, chamber, or area used primarily for the storage of clothes.?
Proposal 1-82
Section 110.16
This proposal expands required marking for flash protection to include dwelling units at other than one- and two-family dwelling occupancies. High rise apartment and condo buildings were the primary dwelling occupancies driving this acceptance.
Proposal 1-84
Section 110.16
This proposal deletes the list of equipment required to be marked with arc-flash warning and uses the phrase, ?electrical equipment, such as?? This change is intended to allow the AHJ to make the final interpretation as to what equipment requires this marking.
Proposal 1-95
Section 110.20 (NEW)
This proposal adds a Table to Article 110 for the selection of proper enclosure types as listed in standards such as ANSI/NEMA ICS6, NEMA 250-2003, and UL 508. The table will match Table 430.91 for motor controller enclosure selection.
Proposal 1-109 through 1-148
Article 110, Part II and III.
These proposals provide several changes and clarification of working space requirements at around electrical equipment. There appears to be an effort by several organizations such as the IBEW, ACC, and IEEE to move NFPA 70E requirements into the NEC.
Proposals 2-10, 2-16, 2-17
Section 210.4
These proposals add several new requirements for multiwire branch circuits. The first will require common disconnect of all ungrounded conductors of all multiwire branch circuits installed in all locations. The second will require that each grounded conductor of a multiwire branch circuit be identified as to what ungrounded conductors it is associated with. The third will that the ungrounded and grounded conductors of a mulitwire branch circuit be ?grouped? using wire ties (or something similar) in at least one location within a panelboard. The grouping is not required if the multiwire branch circuit is unique to one cable or one raceway.
Proposals 2-23 and 2-24
Section 210.5(C)
These proposals revise the requirements for identification of the ungrounded conductors to require ID at the termination, connection, and splice points. In addition, it clarifies that the ID must be for both phase and system. Lastly, it permits the ID scheme to be available in documentation instead of posted at each panel. Similar changes were proposed for feeders in Article 215.
Proposals 2-40, 2-41, 2-50, 2-51, 2-56, 2-57
Section 210.8
These proposals delete the existing exceptions to the GFCI provisions in garages and unfinished basements. The panel has taken the position that equipment produced today is compatible with GFCI?s and that the exceptions are not necessary.
Proposal 2-70
Section 210.8
This proposal expands GFCI protection to all outdoor locations in other than dwelling units. A new exception was added to allow the assured equipment grounding conductor program in limited industrial establishments.
Proposal 2-81 and 2-87
Section 210.8
The first proposal expands GFCI requirements in ?other than dwelling units? to include all receptacles that are within 6? of any sink. The second expands GFCI requirements to include all 240V and less boat hoists whether cord and plug connected or hard wired.
Proposal 2-142
Section 210.12
This proposal expands AFCI requirements to all 15 and 20 ampere branch circuits in dwelling units.
Proposal 2-190
Section 210.52
This proposal revises 210.52 to make it clear that a ?switched? receptacle cannot be used as meeting the requirements of 210.52(A) for receptacle spacing. This section would still allow a duplex to have one-half switched and still meet the requirement.
Proposal 3-155 and 225
Sections 725.8 and 760.8
These proposals were to specifically permit cable ties for support of Class 1, 2, and 3 circuits and fire alarm circuits but were rejected 9 to 4 (UL, IEC, UT, and NECA). The CMP determined it is not acceptable for cable ties to serve as the sole means of support.
Proposal 4-74, 4-75, and 4-82
Section 230.82
These proposals were to permit transfer switches to be located on the supply side of the service disconnecting means but were rejected by the CMP.
Proposal 5-36
Article 100
The panel revised the TCC task group developed definition for neutral conductor and added the words "that is intended to carry current under normal conditions". This solves the problem where an equipment grounding conductor could have been defined as a neutral conductor per the TCC task group?s original proposal.
Proposal 5-45
Section 200.6
This proposal states that conductors larger than 6 awg shall not be required to be marked or identified in conduit bodies that contain no splices.
Proposal 5-84
Section 250.8
This proposal clarifies and reorganizes 250.8 into a list format: Listed pressure connectors, terminal, wire pressure connectors listed as grounding and bonding equipment, machine screw fasteners that engage not less than 2 threads or secured with a nut, thread forming screws that engage not less than 2 threads, connections that are part of a listed assembly, other listed means.
Proposal 5-119
Section 250.32
This proposal removes the allowance to re-ground the neutral at a second building for new installations. Maintains for existing installations, in the form of an exception.
Proposal 5-137
Section 250.50
This proposal clarifies grounding requirements where multiple concrete encased electrodes are present at a building or structure. It shall be permissible to bond only one to the grounding electrode system.
Proposal 5-170
Section 250.54
This proposal will change the term ?supplementary? to ?auxiliary? for grounding electrodes.
Proposal 5-192
Section 250.64(D)
This proposal reorganizes this section. Connectors listed as grounding and bonding equipment and exothermic welding are approved methods for tapping the grounding electrode conductor at the service.
Proposal 5-213
Section 250.68(A) Exception No. 2
This proposal permits exothermic welding or irreversible compression connectors used at terminations together with the mechanical means to attach to the fireproofed structural metal. This clarifies compression lugs are suitable to not be accessible.
Proposal 5-220
Section 250.94
This proposal states the intersystem bonding termination shall be installed securely mounted to the meter socket enclosure, a bonding bar near the service equipment enclosure, meter socket, raceway for service conductors, or near the grounding electrode conductor. The termination must have the capacity of not less than (3) intersystem bonding conductors. A companion proposal, 5-20 added a definition to article 100.
Proposal 5-349
Article 285 Surge Protective Devices (SPD's) 1kV or less.
The article was completely rewritten with several new titles for products, Type 1, 2, 3 and 4. The proposal was written by UL in advance of a new UL1449 publication.
Proposal 7-55

This proposal changes the wording in 334.12(B)(4) from, ?Where exposed or subject to excessive moisture or dampness? to ?In other than normally dry locations.?
Proposal 7-70 and 7-73
Section 334.80
The first proposal clarifies that the exception to 310.15(A)(2) does not apply when adjusting conductor ampacity per 334.80. The second adds the term ?caulk? to the list of fire- or draft-stopped materials that apply to this section.
Proposal 7-88
Section 338.10(B)(4)(a)
This proposal now requires type SE cable to meet all the provisions of Article 334, including 340.80 when installing SE cable as a branch-circuit or feeder.

Section 376.6 (NEW)
This proposal creates the requirement that metal wireways are to be a listed product.
Proposal 9-31
Section 314.16(B)(4)
This proposal will add a new sentence to the end of this section which states, ?A device or utilization equipment of a width that precludes mounting in a single 50mm (2 in) device box as described in Table 314.16(A) shall be judged on the basis of the minimum number of gangs required for this purpose.?
Proposal 9-56
Section 314.17
Revise 314.27 to read as follows:
?(A) Boxes at Luminaire (Lighting Fixture) Outlets. Boxes used at luminaire (lighting fixture) or lampholder outlets in a ceiling shall be designed for the purpose and shall be required to support a luminaire (light fixture) weighing a minimum of 23 kg (50 lb.). Boxes used at luminaire (lighting fixture) or lampholder outlets in a wall shall be designed for the purpose and shall be marked to indicate the maximum weight of the luminaire (light fixture) that is permitted to be supported by the box in the wall. At every outlet used exclusively for lighting, the box shall be designed or installed so that a luminaire (lighting fixture) may be attached.?
Proposal 9-84
Section 404.2(C) (NEW)
This proposal will require a grounded (neutral) connection to be brought to every switch location regardless if is intended to be used or not. This proposal was rejected by the CMP.
Proposal 9-117 and 9-127
Section 408.34, 408.35, 408.36
This proposal deletes sections 408.34 and 408.35 and completely rewrites 408.36. The most notable change is the removal of the 42 overcurrent device limit in panelboards. The second proposal provides the requirement that the number of overcurrent devices installed a panelboard is only limited by its listing and manufacturer?s instructions.
