Does the NEC apply?

the op says the table was listed. are you claiming the listing is fraudulent?
Is this the old dodge of just using a UL listed power cord and pretending that the sticker on the coed applies to the whole equipment? Or just the fact that some specific models have been NRTL tested but other variations have not?
I would think that, unlike the situation for a UL panel shop, each variation would have to be directly tested.
 
So my answers are above in red. We have these pop up all the time. I have called UL on these things several times to find that they are not in fact listed (yet) and that some of the corrections I was calling were the same concerns that UL had. I have found these panels that had the neutrals and grounds bonded, I have had the panels two feet back inside of a stainless steel cabinet, non GFCI receptacles, etc. Why would you think that the load calculation would not be necessary on the plans. How would you know what to run and how would the inspector know what you were supposed to run? Or how would you know if the panel it was coming from was of sufficient size to carry the load?

Now as a disclaimer I was up until 3:00 this morning and am not running on all cylinders so I may have missed something.

I have had the same exact experience with these tables panel neutral bonded, non GFCI protected receptacles for tables in a commercial kitchen area.

I appreciate your comments, John, even if you don't agree with my point of view. :roll:
I am attaching a portion of the drawing that was provided by the manufacturer. Other than the obvious misspelled word, does this look valid, or perhaps suspicious?

The file number should be easy enough to check.
I do not think that the UL logo (with "(R)") is the exactly correct graphic for their mark, but that could just be someone too lazy to import the right graphic into their CAD software.
 
not really enough to say for sure but looks suspicius as the word "number" is misspelled on a official document-- have you searched the CE#?
 
The logo is good according to the White Book. I'm not saying that it's fraudulent, but the one big one I had they told me it was listed and it was in to be listed, but had not been approved yet and UL had a list of corrections for them. And I agree that each variation of those tables needs to be listed unless there is something in the UL standards that allow it.

I'm going to try and research the CE# and see what I come up with.
 
OK just got off the phone with UL and that UL file number is no good. If it was listed by UL there should be a sticker on it somewhere. If it hasn't been listed then you would have to have them come out and do a field evaluation, which is very expensive. Or as your inspector said it's not an appliance any longer and he would inspect it just the same as he would any other electrical installation.

I'm thinking that maybe you do have a fraudulent listing.

I'm grateful you fielded this John. I would have recognized the "file number" to be bogus since it can't be validated on the UL Online Certifications Directory. In absence of that drawing information, I still would buy Charlie's evaluation.
 
I think we have 2 issues here.

Assuming the listing is valid and, key for me, would be the stated MCA value. It gets treated like any other equipment such as an air handler with factory subdivided loads, etc. Under these circumstances I feel certain that Charlie's original argument is valid and the inspector is wrong.

Now the fact that this may be a fraudulent listing is another matter. In this case I think the inspector could reject it outright, no matter how the loads are calculated, as it is wired equipment not done by the EC in the field and under his permit, but rather by unknown people with no discernible qualifications. This is one reason many AHJs require a NRTL on anything that the EC does not wire.
 
It is not uncommon these days for someone to misrepresent a NRTL listing. I probably see it 2-3 times a year. I also have a solid contact with an UL Senior Regulatory Engineer that is very helpful if direction is needed. Any time I see the CE mark (European Union) I will approach with caution as it has no representation of life safety testing.

Just putting 2 and 2 together - you are an inspector in CA, Charlie claimed to be having a problem with an inspector in CA.....;)


But I have to agree with you - if one can prove there is a fraudulent claim the item is listed, if the listing is valid - inspection stops at the supply terminations.

Not every listed item is directly tested - that would add a lot of cost to everything. I don't know all the rules here but would guess there may be random sample testing at times, or re-testing whenever a change is made to a product. A product like we have in this thread may be able to be built by some kind of approved panel shop or equivalent, but probably still has some kind of regular auditing of what they have been doing to make sure they are in compliance with listings. If equipment has optional standard configurations, each configuration is probably on file in one way or another for listing purposes - if they are legitimate listed options .

Well now you guys have really stirred up a can of worms....:lol:

Sounds like this job just got more expensive!

If I were owner I would be thinking about either returning the product, filing lawsuit, or somehow getting the supplier to make things right.

I had a recent call they are building a new jail in my county, I am not the electrician nor am I involved in any way with this project other then I am a taxpayer. The county opted to have a company bring in some "modular" jail cells, that supposedly they build off site with plumbing, wiring, everything necessary in the unit and they ship to the site and install them. I got a call one day from the company that sold these cells, and one of first things the guy leaves in his message is we need someone to file permits..... I was completely not interested in even returning his call - and never did, this comment alone sent a red flag up for me and I didn't even pay much attention to anything else in the message. A few weeks later I happened to be on a job with the area inspector and asked him if he was having trouble with the crew installing those cells - he pretty much assured me of my suspicions that I wanted nothing to do with that job. They are from out of state, have no state licenses, don't have any listing on their product either, then of course there are issues with the wiring construction/methods that are a part of these units.
 
... if the listing is valid - inspection stops at the supply terminations.

...
I do not agree with that... at least not completely. :happyno:

Just because an item is listed, labeled, and/or identified for [a] purpose, depending on case, does not remove the item from inspection jurisdiction. All such items must still be evaluated for their suitability with the installation. A good example of that was mentioned earlier: a listed unit with integrated, non-GFCI receptacles installed in a commercial kitchen. So inspection doesn't automatically stop at the supply terminations.

What do you do with the bond from the neutral if left in place will bond the neutral in the (sub-panel) through the feeder supplying this equipment's (prep-table) panel
 
I had a somewhat similar situation with a plugstrip, except I was asked to pick the plugstrip and call it out on my drawings, so I told them the unit had to be compliant with short circuit current available at the unit. http://cdn1.servertech.com/assets/d.../original/CB-24VDX403_50_60amp.pdf?1326172889

The integral 60A breaker at the input to the internal plugstrip circuit is only rated at 5kAIC, but we had 8kA available. The 60A intergral breaker was supposedly part of the "black box" made up of the UL Listed assembly. I was not to worry about it, since a plugstrip doesn't have to have a SCCR.

We argued a while about whether I was providing a branch circuit to the plugstrip or a feeder to a 60A "distribution". If it was a branch circuit, it made it even more likely that I shouldn't worry about the SCCR for a plug connected UL listed product.

Technically the manufacturer is responsible for that. Whether you wish to work with them to remedy the situation or not, is entirely up to you. If you do, make sure to get everything in writing, including liability indemnity of yourself and affiliates.
 
And if the unit really had been UL listed, either that bond would not have been there or there would have been instructions for removing it "in accordance with local codes"

I was going to say something similar as far as GFCI protection for receptacles in a commercial kitchen. If the unit has a valid listing and the equipment is intended for commercial kitchens, it likely has GFCI protection, or instructions requiring GFCI protection in the supply circuit.
