So what do we do with the code? We try to go through it step by step in accordance with the book, but that's only if we don't have a template from you of how what you would want us to cover. One of the things as we said with TPC, what we try to do is try and make it relevant to you. One of the things as an instructor that I really like from my students is be open. Tell me what you want because it is one of the things I take great pride into in customizing these things for you and only covering the parts that are necessary for you as opposed to covering a whole thing and wasting your time. But keep in mind in general, how we organize the course is we go in order in the book. So, as you can see here, we start with article 90.2. Across the NFPA 70 series, as an NFPA 70 and NFPA 70B, and 70E, one of the things they included to be was the removal, if you notice, that's in bold there because before it was more generically talked about, but now there's talking specifically.

As we're upgrading or moving all the equipment, we still need to follow the appropriate safety that's involved with it and now the articles enforcing that. We have the various sections of the book as they're divided. In general, if we make it in a class, if we make it through chapter three, we're doing good. And the reason I say that is because once you get beyond chapter three, it's pretty much the same stuff. It just goes into more specific applications. And by then, our goal is to make sure that you have an understanding of how the book is organized and how the language, and what it intends to communicate. Like I said, typically in our courses, we could try to get two chapters one, two, and three and then we'll answer specific questions regarding the other articles if you have them as they pertain to you.

I'm in many of the other NFPA series, one of the things you got to realize with any these books is they typically have an article 100 in the beginning of the books that outlines definitions, but you will find keywords that you will find in two or more articles throughout the document. If in the event that is only found specifically in that article, that book, it will be in the point two section of that article and that is the only article to which those that specific set of words refers.

One of the things too that we try to do in the National Electric Code is to make sure that it is used correctly. And that's one of the things why I say it's important to have an understanding electricity, because this is not designed to be a design manual, it's designed to be a standard. And understanding the proper context is critical because in many cases, there's a lot of misconceptions out there about any part can be used any way you see fit, and that is one thing that at least for my classes I try to steer my students away is trying to understand the appropriate context. One of the things that help with that context is article 100, the definitions.

Also, they've gone up point out listing. I definitely know for sure in NFPA 70E they talk about it. I'm confident they do in the latest NFPA 70. If they haven't done in the 20s in this latest one, they're definitely going to do with the next one. And that is that they added a section to NFPA 70E that specifically enforces manufacturers to make sure that their equipment, whatever they sell you that is rated for safety related is actually it is what it says it is. There's a whole separate enforcement just to make sure that if we go buy some, we don't buy something that even though they say it, but we realized we just bought some snake oil.

The code is being used as an enforcement tool in that manner to make sure that the manufacturers are in fact holding themselves to the standards that they claim they're making whenever you go and buy something that isn't adherence to the code it. Part of that is here, the examination, identification, installation, and of course, listing. Listing refers to, if it's been tested by listing agencies such as Underwriters Laboratory, CSA is for Canada, and then there's TUV as for Germany for example.

So, one of the new things also, this is one of those things that's been kind of over the years, experts have been him hauling back and forth. I don't know how to where to put about it, but they've been going. Some people say you need torque. It's too much torque, there's not enough torque, but nobody ever said this is what it needs to be. This is one of the things that this new article is trying to address. Because even in my own research, I have I haven't found specific saying, "This is what you need to do." They're always dancing around it and then example what I mean by that is like one of the things I talk about in my class, like if you look at an expo for example, that you would know that based on tick marks around on the top of the expo how hard that metal is.

Well, I'll give you example, like if you have a bolt with no tick marks, typically made out of aluminum and the torque specs on that say it's like you know 500 inch pounds, you're going to rip the head right off that bolt. These are like where the kind of engineering and technician arguments is centered around. The code then is trying its best to address this in a general manner, while the same time, saying that torque specs are important and proper use of torque tools are also important.

One of the things also that I mentioned earlier in the course. The use of specialized tools as well, including thermography, vibration analysis, and this is becoming one of those preferred maintenance practices mainly because the idea is to be noninvasive. So, one of the things that code down was trying to address is using the noninvasive techniques of thermography and vibration analysis, those types of techniques as a method for you to conduct maintenance. And even the research among engineers who conduct maintenance, the general school of thought is, "If it ain't broke, don't fix it." So that's one of this use of technology, that's the intent of it. And a good predictive maintenance, predictive mains usually centers around thermography and vibration analysis, is that you're not reactionary, you are more proactive, especially in the production industry because that will allow production facilities to plan ahead of time rather than have an emergency knee jerk shut down the plant that is unplanned.So, this is one of those tools and this is one of the reasons why the National Electrical Code is addressing it
