[B]Installation[/b] instructions are considered part of the UL Listing. All info added
by the manufacturer in addition to that required by UL must be in
compliance with NEC and UL standard. The UL standards used to
investigate and List products, contain specific requirements regarding the
content and appearance of the instructions. Installation instructions are not
required to be marked with the UL Mark, but they are required to be
provided with the product bearing the UL Mark. Some products are not
required to have installation instructions because the National Electrical
Code contains all the necessary installation requirements, such as outlet
boxes and various wiring methods. UL staff review the instructions, both in
the initial evaluation of the product, as well as during the continual
inspections at the factories. The clarity of the instructions is considered in
the review.
If there are questions regarding installation instructions, please contact
your Regulatory Services Representative.

I had a light installed in a shower. The manufacturers literature indicates
that it must have a GFCI installed. Is the GFCI required as a condition of
Listing or simply something that the manufacturer wanted to add
A
UL Listed Luminaires are evaluated for compliance with the Standard for
Luminaires, UL 1598. The UL Standard does not require GFCI protection
for luminaires used in the shower area. If the manufacturer chooses to
require GFCI protection in their installation instructions, then Section
110.3(B) of the NEC? would be applicable.

M.D. post it as many times as you want, if the particular instruction is not part of the listing 110.(3)(B) does not apply.
Or do you think my use of non-Hewlett Packard Ink is a 110.3(B) violation as the instructions say to use genuine HP ink?
I ain't gonna argue about it, any one can read the section itself and decide why the words 'included with the listing' where included in that section. :smile:

You would have to look at the listing criteria to know one way or the other.
Or is my wife risking a 110.3(B) violation when she uses generic bags in her Hoover vacuum when the instructions say to use Hoover bag # etc?

In front of me is a box of leviton duplex receptacles (cat.#5320-wmp) typical elcheapo type.It only says to "loop wires clockwise3/4 turn around terminal screw" It says nothing else except "to be installed and used with appropriate electrical codes"

Bob ,I 'm not saying it, I'm reading it, right along with you,... I just can't find anything to support that they are not part of the listing and labeling ,.. If I could I would post it .. I'm not saying that I know it, I'm saying it is what is being taught and what is accepted by the experts at U.L. and many experts in our trade.

What UL says and what the code says are two different things. The UL statements are nothing more than their interpretation of the code rule in question. It is my opinion that the only instructions that are actually required to be followed by 110.3(B) are those that are actually used in the testing and listing of the product. Everything else is just manufacturer's instructions.
I showed the following statement found on a spec grade name brand receptacle to a UL and NEMA rep at the Western Section IAEI meeting.
I asked both if this statement is a 110.3(B) instruction that must be followed. The UL rep said yes, so I asked if I could install the receptacle in a raised cover, he again said yes saying you have to use common sense. The NEMA rep said it is not an instruction that is required to be followed because it does not contain the word "shall".
Also as I have stated many times UL is talking out of both sides of their mouth on this issue. As long as classified breakers exist, I will never accept UL's statement that all provided instructions are 110.3(B) instructions.

MD,
Back to the receptacle in my post. Do you think that the manufacturer intends to prohibit that receptacle from being used in any installation other than a wall box? Is an manufacturer's instruction that does not contain the words "shall" or "shall not" a binding instruction?
Don
And the only opinion that is completely binding is one issued by the US Supreme Court.

The way I read those instructions, the only possible installation is in a wall box using the screws that were provided with the device. The instructions that are provided give no other options. If we have to follow the supplied instructions, we can't install that device in a raised cover.

Look folks , way back I thought there was 3" of bare current carrying conductor.
Bob (Iwire) said that he would like to see where it was a violation to have that bare conductor employed .,...I settled on 110.3(b) I would cite it based on that section of the code If the installation instructions called for something less than 3" .
If I were asked why I think they are part of the listing ? I would say that I have been trained to regard them as such at all of the seminars I have been mandated to attend to keep my license.
I would love to find out what the Supreme Court would have to say about this case,.. :smile:
110.3(b) says what it says , the question is are installation instructions part of the listing and labeling.I am of the opinion based on what I have read and from what I have been taught , that they are .
I know I may be incorrect but if the device instructions called for 5/8" stripped and someone stripped 3" I would cite 110.3(b) . There are actions the installer can take , It is not personal just a difference of opinion
