I'd have to say that we have finally touched on a variation a what was a pet peeve of mine when I worked as an electrician.
The 2 variations on this theme are 1]The 'Designer suugests a fixture-for some reason designers more often than not seem to lean towards fixtures manufactured in europe-the downside to this is that this will also increase the likelihood that the fixture will not be UL listed-I'm not saying that because something is produced in europe it willnot be ul listed --I'm saying that when it comes to lighting fixtures in particular this problem will present itself.
That was variation 1.Variation 2 is the reall good one.
2]The designer and client[thats our eager h/owner] head off for a day of lighting fixture shopping down to Canal St. in NY,with side trips up and down Bwery,Spring,And Grand avenues downtown[Hotspots for Antique shops,lighting/antique shops,and lighting shops that sell fixtures as new that should be considered as antiques].
The result that is eventually handed to us -the electricians is an 'item'-I am generally reluctant to call it a fixture.
You find yourself studying the "item" and saying to the h/owner "Did the store have this displayed as it should be installed--ya know,I mean this is a wall sconce so was it installed on a wall display and lit up?"
At this time as you hold your breadth,because you're pretty sure you know the answer---
well if things go the wrong way the h/owner will say
"No -none of the fixtures in the store were lit up or on a wall-they were hung fron a chain on the cieling".
It is at that time you realize you now face variation2--you don't have a fixture in your hand-you have a piece of art in your hand-and you now know that you now are faced with explaining that a piece of art is just that -it is not a fixture no matter how many zip cord and bulbs youjury rig to it.
Once again you realize that a big shooed brightly colored imaginationland interior designer has somehow found his way into the world of electric-a world which makes little sense to him,just as his kind is often very puzzling to us.
Variation 2 is 'A fixture is a fixture and a piece of art is just that-a piece of art."
Art should not be electrified and turned into a fixture-
It should be hung and then illuminated to bring out all its beauty thru the use and proper installation of a fixture designed for the purpose.
While normally I am quick to accept the hard guy rep for my view on something like this,I will say that in respect to this in particular -my feelings came from too many years working high end jobs where this scenario was THE NORM-we were given pieces of art the the designer said was a fixture-however there was no way to mount this fixture[allways seemed to be a wall sconce]-why?because it never had been intended to be used that way.
What did we do-we did unfortunately what so many of us will do-we got the job done-I'll give you one example--
H/owner purchases thru his designer 25 wall sconces .When he saw them they were hanging from the cieling..,by a string.
Thats because there was no mounting method incorporated in the design of this fixture.
And the answer once again is because it wasn't a fixture.
We designed a method using a spun brass back plate[in keeping with the 'tone' of the fixture] that allowed for proper securing of the device or and or
fixture clearance,and ease of removal if repairs were needed
I disagree but, if that is the case, how are we going to have whole buildings tested in a lab?
Wait a minute, how will we know the UL guys are qualified ......... oh yeah UL will tell us so.
So you are saying you don't think an inspector has the knowledge, experience, or credentials to approve anything.

how can an inspector say, with reasonable confidence, that a modified light fixture does not represent a fire hazard, without endangering someone and/or leaving the public culpable for a future lawsuit ? Inspectors are already tasked to inspect items well beyond their ability to adequately perform: they can only perform (imo) the most summary inspections for the most obvious and routine items. Furthermore, why would the public even want inspectors to be put in the position of taking on this responsibility (regardless of what has been going on in the past). It may not be convenient for electrical installers to have to deal with non-conforming items, but if they want to install them then the onis is going to be on the installer/owner to provide some kind of reasonable safety certification (perhaps there is a business opportunity here for some entrepenuer, since the alternative ie. UL is so expensive)
We will forget about having skilled installers and inspectors, we will just have mindless robots doing the work and then we will pay UL to come out and list the building. And then when it needs to be changed we will have UL come out again and again and again. :roll:
Wait a minute, how will we know the UL guys are qualified ......... oh yeah UL will tell us so.
I will continue as I always have, and if I build a fixture or a control cabinet I won't loose any sleep worrying about it being safe without a third party listing.
As pointed out earlier, why would you think a UL representative is any more qualified than we are?
And as far as lawsuits, there will always be lawsuits even if everything associated with the suit is third party listed.
Roger
UL does not "approve" equipment, material, etc...
UL lists and labels.
I have actually had an inspector have me remove the fixture to check for the sticker at a final inspection:grin:

Roger: "As pointed out earlier, why would you think a UL representative is any more qualified than we are?"
The main reason why they are more qualified than *most* electricians or AHJ's is that they are fully familiar with the UL standards that the product is tested to.
That could be a big problem too.They might even be 'dreaded' engineers that actually perform testing in the lab on the very same items.:roll:
They can if they are employed to do so.In many cases, they can bring lab equipment out to the site and test the product. In other cases, they will get involved with a manufacturer if a listing is questionable or mis-applied.
I agree and it is sad IMO.Third party testing serves a purpose for 98% of all applications. However, if the AHJ doesn't require or recognize third party testing and validation to NEC standards, then your professional opinion (and the NEC) is about all you have to convince the AHJ to approve. However, they might not want the liability or have the expertise to trust in your explanation (or their own), hence the reasoning for a third party testing organization.
The moral of the story is if you modify a UL listed product on site (in a manner for which it has not been designed for), the NEC provides the AHJ every right to pass on approval until the product can be independently tested and verified. UL Listings are static - meaning that they only cover product that was submitted to UL in a particular configuration or condition for testing. Once modifications are made, the item would no longer be identical to the tested and listed item - technically.
if a fixture is built out of UL listed parts does the entire fixture need to be UL listed? if somebody decided to build custom fancy fixtures using UL listed sockets, cord caps and lamp cord is this ok to do?
my father made a couple light fixtures out of wood to sell. all the parts are UL approved and i checked the wiring over.
heres a story. one house we wired the guy bought an old wagon wheel to hang from his ceiling. he wanted lights on it so it would look like an old western saloon or something like that. we bought a bunch of candelabra sockets and wired the lights using lamp cord. i have no problem with this at all and it still works to this day without one problem.
Thank you for inserting *most* but regardless, that still doesn't mean they are any more qualified to approve a product.
That could be a big problem too.
They can if they are employed to do so.
I agree and it is sad IMO.
I have not been talking about altering a product in this thread.
