It would be a big help if you gave us your password so we could access these standards as not many in this forum could afford to buy these standards.

As you have pointed out in your post these standards are for information purposes ONLY and are not mandatory to any installation but simply something that the manufacturing of the end product is based on.

The one thing that I have learned over the years is that the Home Inspector has one of the hardest jobs on the job market today. Their knowledge base has to be astronomical due to the enormous amount of different items they are responsible for looking at.

This is why it is so important to ensure that the information we as educators give them is correct.

Case in point;
I went to evaluate the electrical installation of an old house that had two wire circuits where the devices was changed to grounding type and protected with GFCI devices.
The Home Inspector had ask for an evaluation of the electrical system and pointed out several items one being that the GFCI did not operate when he used his tester.

Included with the installation instructions with every GFCI device on the market today is the testing procedures for testing the device. The instructions clearly state to use the test button on the device and not rely on the button of the little plug-in tester as this Home Inspector had did. When I pushed the test button on the GFCI device it functioned as it was designed to do.

Now what choice did I have but to report that the GECI devices in the house were working properly? How did the people involved in the selling and buying of the house look at the Home Inspector’s report after getting three different electrical contractors look at the electrical system and coming back with the same report, the GFCI devices are working properly.

With the UL Standards that you have posted that most of the members of this forum will never see and are not part of the instructions included with the labeling of the equipment what has the Home Inspector gained?

Instead of adding fuel to the fire of the animosity that exist between Home Inspectors and the building trades today I feel that there is a great need to make sure that they both are working in unison for the same end result. In order for this to happen it is imperative that they both have the same understanding of the codes and inspection process during the building process.

In order to have a better unison between the Home Inspector and the building trades it is important to make sure that they both understand why certain things are the way they are when doing home inspections today.

As outlined in the paragraph that you highlighted it is clear that the UL Standards are not part of the codes and are not enforceable so to quote a section of one of these standards as something to use as a reference for the Home Inspector is not helping to have an understanding between the Home Inspector and the contractors of the building trades. In my opinion it is doing both the Home Inspector and the contractor a disservice.

A good example of this is UL Standard 67 that keeps reappearing throughout this forum. If this standard had always been in effect and was enforceable do you think that from border to border and coast to coast the doubling of neutrals would have taken place? Do you really think that for decades that all the electricians and electrical inspectors weren’t doing their jobs correctly?

I hope that I am always able to give my audience good helpful information that they can take out into the work place and apply but the one thing that they can’t take into the work day is standards that are not enforceable.
To make a statement that according to UL Standards this or that is not allowed then requires the person making that statement liable to substantiate that statement.
Being that none of these standards, by word of the code book itself, are mandatory parts of the Code how could they be quoted as a hazard?
How could a Home Inspector substantiate his remarks?

[jtedesco1]

Mike:

Where did you see any reference related to any quoting of any standard, I asked for help identifying some of the equipment the inspector will see in dwellings and commercial buildings. I will remove the UL and numbers, but remember these terms are what the AHJ will use in order to approve any job.

Labeled. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner.

Listed. Equipment, materials, or services included in a list published by an organization that is acceptable to the authority having jurisdiction and concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation of services, and whose listing states that the equipment, material, or services either meets appropriate designated standards or has been tested and found suitable for a specified purpose.

I should give out the password, what password, you want me to lose my job? Besides, I don't have any password, major companies pay for this service and use the standards that they need in order to investigate a product for a field label.

[Mike Whitt]

Joe

You finally hit the nail on the head.

When the manufacturer installs the label he is saying that the end product complies with these standards and when listed that a NTRL has confirmed that it also complies with that NTRL’s standards.

In the scope of the AHJ this could be any one from the installer up to and including the Supreme Court of this great nation. As referred to in the definition of Labeled the AHJ would be;
The phrase “authority having jurisdiction” is used in NFPA documents in a broad manner, since jurisdictions and approval agencies vary, as do their responsibilities. Where public safety is primary, the AHJ may be a federal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the AHJ. In many circumstances, the property owner or his or her designated agent assumes the role of the AHJ; at government installations, the commanding officer or departmental official may be the AHJ.
Possibly the governmental body responsible for the adoption of the NEC.

Take a close look at 90 in the front of the NEC where it gives the layout of the code.

90.3 Code Arrangement.
This Code is divided into the introduction and nine chapters, as shown in Figure 90.3. Chapters 1, 2, 3, and 4 apply generally; Chapters 5, 6, and 7 apply to special occupancies, special equipment, or other special conditions. These latter chapters supplement or modify the general rules. Chapters 1 through 4 apply except as amended by Chapters 5, 6, and 7 for the particular conditions.
Chapter 8 covers communications systems and is not subject to the requirements of Chapters 1 through 7 except where the requirements are specifically referenced in Chapter 8.
Chapter 9 consists of tables.
Annexes are not part of the requirements of this Code but are included for informational purposes only.

Well Joe you ask all these fine folks what part of these standards they use but you didn’t give them access to the standards. How are they to know anything about the standard if they can’t access them?
For a fee one can obtain access to these standards via the internet with a User Name and a Password that can be obtained from UL or a hard copy can be purchased.

When my Honda Element was manufactured there was a requirement for the metal in the frame to meet a certain standard. When I bought my Honda Element I hired a mechanic to check that all the standards was followed and to call out any that didn’t
Now that sounds silly don’t you think?
The same is true about these standards that you keep posting for the Home Inspector to quote.

[jtedesco1]

Mike:

I am sorry if I did not make it clear to you, I posted the standards to give the names and types of equipment.

I was not expecting the Home Inspector read each standard.

Look at the list and tell me which equipment we inspect, such as AFCI's and GFCI's. I hope this helps.

I will try to make my self clearer in the future.
