I looked at a job that had all of the chain hung flourescent fixtures fed with SJO type whips.The area is a dry location,a warehouse.The owner wants more lights put up. My question is about the SJO cord feeding the fixtures.Usually I use MC w/ stranded conductors to feed chain hung fixtures.I'm looking at 410.67(c).I would think the SJO cord is a violation. Any feed back is greatly appreciated. ToHo

You're weeding in the wrong pea patch. 410.67(c) deals with "Special Provisions for Flush and Recessed Luminaires."

Put your hoe in the row marked 410.30(C)(1). The existing installation may still be incorrect, but at least you'll be citing the correct section.


Few things are harder to put up with than the annoyance of a good example.

Tom.. Thanks
I skipped right by 410.30
The only question I have would be the type of connector you would use for the SJO. The strain relief connectors w/ the grips go for $15.00 each.Anyone have any cheaper connector that is listed for this use.Thanks ToHo

I'd check with inspection.We were allowed to run SJOW whips to switched receptacles on the premise that the lights may have to be removed if we have need to move large equipment around the plant.The receptacles had to be placed directly above the light.The SJO does begin to rot in hot ceiling space after 5 or so years.

Most two-screw romex connectors are listed for use in this sort of application with SO cord- check the box. They cost maybe 30 cents a piece.

Thanks for the replies.
I'm wondering if the existing installation w/ SJO cord was installed because of the distance between the fixture and the junction boxes.Using a MC whip would limit you to 6ft.I can't find any limitations in lenth w/ flexible cord in 410.30(c)(1)??Thanks ToHo

Toho... no limit on length for the cord, but, remember the requirements in 410.22. I've seen people get pretty sloppy with this type of installation.

410.22 Luminaire (Fixture) Wiring — General.
Wiring on or within fixtures shall be neatly arranged and shall not be exposed to physical damage. Excess wiring shall be avoided. Conductors shall be arranged so that they are not subjected to temperatures above those for which they are rated.

ToHo- Why would there be a limit on the length of an MC whip. It can be longer than 6' as long as its supported. Cable tie it to the chain that's supporting the fixture and you're good. SJO cord can only be used if it plugs in to a receptacle at the ceiling. You cant hard wire it to a j-box because that makes it a permanent wiring method.

Thanks Greg..
Through my entire career w/ Local 3 I never made a fixture whip longer than 6ft.That was drilled into our heads from day one. Now that I'm on my own & looking for some basis on the rule, I only see 6ft. max rule in 410.67 Special provisions for flush and recessed Luminares ..Also.. It seems the use of stranded conductors in the whip is mentioned in 410.28 for chain hung fixtures etc. I can't honestly say I have ever fed any drop in flourescent fixtures with solid wire. You learn something new everyday. I thank everyone for their responses...keep them coming!! Thanks again ToHo
