Water hose in raceway

[RichB]

Hi guys, Here's a new one for you. We have a city that wants to put a flexible hose inside a street light to water their hanging baskets. We have USE or THHN/THWN supply conductors with ESNA Brand fuse kits then it goes to a 2 conductor pole and bracket cable up to the luminaire. I have looked through Chapters 3 and 4 and can only find anything similar in 300-11b(1) that even remotely applies.

Is this a violation and where would I look?

Thanks in advance!
Rich

Forgot to add--everything is listed for wet locations and I know that all feild made holes need to have engineering approval.

Gut feeling is this is a violation but I need references before I can tell them no.

Thanks

That might be covered under "Foreign Piping".

Violation of 300.8. Tell 'em you can do it if you remove the electrical conductors.

 

[Article 90.1]

I say look in 680, because the light pole is now a fountain. Not really, but maybe.

I like it! Or maybe it can be a shower. With the flowerpot as the basin, we're going to need a GFCI receptacle if the homeless dwell there.

Just one word: "Disney".

They have many lamp posts with auto-watered plants hanging off them.

I know the municipality of Reedy Creek is a tad odd, but they do approximately follow the NEC...

410.30 (B) permits a metal pole supporting a luminare to be used as a raceway it does not require it to be used as a raceway. If you can make the pole "not a raceway" you can run anything you wish in it, including a raceway to supply the luminare.

My take is that if you are using USE that does not require a raceway. It can be argued that when you add the hose to the inside of the pole it is not a raceway anymore, but since USE does not require a raceway it is not an issue.

THWN, OTOH, does require a raceway.

I think I would disagee on the USE situation. USE when above ground must comply with 338.12(B) which requires it to be in a raceway.

Yes. Also the first 18 inches emerging from grade must be in an enclosure or raceway 300.5(D)(1).

Who owns the street light? 90.2(B)(5) may apply. If it does, you might not be able to do anything about it. JMO

What does that section actually say?

Yes. Also the first 18 inches emerging from grade must be in an enclosure or raceway 300.5(D)(1).

You may want to read the section again.

Thanks for all the info folks--Geesh can't believe I overlooked those references--

Here's what I sent the engineer types who asked(after I read all those sections)

It is a violation of 300-8 unless they find a way to make it "not" a raceway-or that they may tell us inspectors it is ok under 90-2(b)(5)(b) and 90-2(c) then we will allow it(as the city owns the lighting and is in their right of way and contract State DOT to maintain and repair)--otherwise no go.

Thanks again for all help!--
