Chapter 6 Special Equipment can be intimidating at first. This is partly due to its size (nearly 100 pages) and partly due to the sheer variety of “special” equipment. Also, it’s hard to pick out organizational themes. You can see that articles for transportation-related equipment are grouped, and articles for alternative energy are grouped. Generally, groupings are small and, thus, numerous.
The saving grace for the typical electrician is that installing specialty equipment tends to be a specialty. For example, not just anybody can work on elevator systems; you must be certified. And if you’re certified for that, you probably aren’t doing much else.
If you don’t work for a company that specializes in electric signs, you probably will not need to learn Art. 600. Solar and wind installations are in demand, but these are installed and maintained by companies that specialize in them. Unless you work for such a company, you probably don’t need to understand the NEC requirements for these installations.
If you don’t work on special equipment, don’t sweat Chapter 6.
