400.7, 400.8, vs. 410.30(C)? 2005NEC

[steveray]

Open ceiling retail store...wants to run SO cord from luminaire to luminaire for all of their exposed lighting....400.7 seems to allow it #(2), 400.8 makes it a little wishy washy IMO with not as a substitute for fixed wiring and not attached to building structure......410.30© says listed and/or plug...

Anyone have some input or guidance?

Thanx!

400.7 (2) allows it the other two do not apply

400.7 (2) allows it the other two do not apply

Sorry, 410.30 does apply provided

© Electric-Discharge Luminaires (Fixtures) See related ROC

(1) Cord-Connected Installation A listed luminaire (fixture) or a listed assembly shall be permitted to be cord connected if the following conditions apply:

(1)The luminaire (fixture) is located directly below the outlet or busway.

(2)The flexible cord meets all the following:

a.Is visible for its entire length outside the luminaire (fixture)

b.Is not subject to strain or physical damage

c.Is terminated in a grounding-type attachment plug cap or busway plug, or is a part of a listed assembly incorporating a manufactured wiring system connector in accordance with 604.6©, or has a luminaire (fixture) assembly with a strain relief and canopy

Thanks Gregg....but if they are wiring them in "series" there is no outlet above and no plug?.....And then I also need the listing?

Yes one of C ©

$00.7 #2 allows it for one fixture. You are now treading on 400.8 #1 and IMO this would not be compliant

 

[Dennis]

sorry that should be 400.7 in the post above

I did not see the "wired in series" they would need to be wired and suspended directly bellow the outlet as stated in C (1).

410.30 in 2005 is now 410.62

I agree that the flexible cords would be a violation the way they want to install them. We do need to look past 400.7 and squarely at 400.8

In addition, 410.30 in 2005, the panel had the following to say:

Comment No. 18-65 on Proposal No. 18-40a 18-65 Log #2188 NEC-P18

Final Action: Accept in Principle (410.6, 410.27(B) & ©, 410.30©, and 410.30©(1)(2)© )

Comment on Proposal No: 18-40a

Recommendation: Change the proposed text to read as follows:

410.xx Listing Required. All luminaires, and lampholders, and lighting assemblies shall be listed.

Additionally, the text of 410.27(B), 410.27©, 410.30©(1), and 410.30©(1)(2)© should be modified by adding the word “listed” back into the sections as shown below:

410.27(B) Size Unless part of listed decorative lighting assemblies, pendant conductors shall not be smaller than 14 AWG for mogul-base or medium-base screw-shell lampholders or smaller than 18 AWG for intermediate or candelabra-base lampholders.

410.27© Twisted or Cabled Pendant conductors longer than 900 mm (3 ft) shall be twisted together where not cabled in a listed lighting assembly.

410.30©(1) Cord-Connected Installation. A listed lighting assembly shall be permitted to be cord connected if the following conditions apply:

410.30©(1)(2)© Is terminated in a grounding-type attachment plug cap or busway plug, or is a part of a listed lighting assembly incorporating a manufactured wiring system connector in accordance with 604.6©, or has a luminaire (fixture) assembly with a strain relief and canopy.

Substantiation: The term “lighting assemblies” is undefined, vague, and likely to lead to a variety of interpretations from different authorities having jurisdiction. Will optional parts that are normally shipped separately from a luminaire be considered to be lighting assemblies which must carry a listing mark? (For instance, visors or vandal guards). Are poles lighting assemblies? To address this problem, the term “lighting assemblies” should be removed from this proposed general listing requirement, and the requirement for listing should be added back into the appropriate specific sections that previously referenced “listed assemblies”.

Panel Meeting Action: Accept in Principle

Accept the recommendation as submitted with the following revision to 410.30©(1).

(1) Cord-Connected Installation. A luminaire or a listed assembly shall be permitted to be cord connected if the following conditions apply: (remainder of 410.30©(1) to remain as is in the 2005 NEC)

Panel Statement: The panel accepts the recommendation with the addition of the words “luminaire or” to 410.30©(1) to restore the text to that of the 2005 NEC. The panel notes that “fixture” will be removed throughout the NEC based on the TCC direction.
