    The NEC itself is not law, that is correct. However, it IS the law in places that have adopted it as such, and those places are a majority of not only the US but other countries as well. Here in Michigan, our electrical law is called the Michigan Electrical Code, but it references about 90 percent of the NEC as adopted law.

    The gist of your post was excellent, however. Especially the part about the connections.

    Yeah it's a funny thing. Insurance companies, especially the big ones, basically ignore local ordinances that are not exclusively adopting the NEC in full. They will apply the NEC to the fullest extent on claims in areas not using it as local codification. Unfortunately people think the are covered if they adhere to local codes, and most times they truly are not. Here the NEC is referenced specifically as the code in it's entirety, with additions. (For instance, in my township wires leading into the home as antennas or feedlines must be 12ga, not 14ga as in the NEC. Who knows why, but it exceeds NEC standards regardless).

    This explains also why (along with other factors) insurance premiums are cheaper in certain areas; the insurance companies know they can argue that any installation, whether power based or a station, is not in compliance with the NEC. This mean they pay-out less on claims in regions that do not use the NEC for their local codification, and therefore the insurers can afford to offer more "competitive" premiums.

    Really enjoyed the process and the "if first you don't succeed" approach, with no cuts, as sometimes is true with a real process especially out in the field. And of course all us engineers may be analyzing deep down in our left Brain the plusses and minuses of what we are seeing while all the time thinking this looks like almost as much fun as playing with Thermite !! Which it may be ??

    Thanks Mark and Ed

    I am familiar with UL regs for other industrial fabrications. What is the UL reg being cited here for it being "approved"?

    "Approved" means "Acceptable to the authority having jurisdiction". It has nothing to do with the UL's regs. It simply means that whoever is enforcing the NEC has given their blessing.

    "Listed" means "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 either the equipment, material, or service meets appropriate designated standards or has been tested and found suitable for a specified purpose."

    The UL is not the only acceptable organization for listing. It's just the most popular.

    Thanks for beating me to the reply. I think it is interesting that bogus listing documentation...generally fake stickers have been applied recently to cheap knock off's of listed equipment and materials. Common ones have been electrical plugs and receptacles that can't withstand rated current without melting or distorting or wiring insulation that catches fire.

    And by the way...UL is the most popular in this country because it is the oldest listing jurisdiction recognized in this country. At one time they were the only listing agency in this country.

    The inspection departments authorize building to a certain standard. They would be the AHJ when it comes to adopted legal standards. They are not adopting laws for the benefit of the insurance companies. The insurance company can be, and many times also is an AHJ, or "Authority Having Jurisdiction". The insurance companies can adopt their own requirements for the purpose of deciding if something is insurable or not. In that case, the insurance company is an AHJ. That means its very possible to have two or more AHJ's that refer to the NEC and affect the owners of electrical installations.
