It will come as no surprise that electrical professionals have a total love hate relationship with the National Electrical Code. Every three years, the NEC is revised, with the 2011 NEC being the latest version. Unfortunately, for many, three years seems like a very short period of time. They had only just been able to get completely to grips with the 2008 NEC and the 2011 NEC appeared. Just when they thought that the last set of revisions was fully understandable and can be applied, it all changes again. The 2011 National Electrical Code actually has 25 changes compared to the 2008 NEC, so electrical professionals have once again had to stop and learn about new things. The original document was printed in the 1890s and it would stand to reason that it doesn't need much else than a few revisions and tweaks. In reality, however, new technologies and new products are being developed at an ever increasing rate. Also because new research findings flood the market from private and public groups alike, the changes are actually very drastic.
In fact, some of these revisions are so comprehensive that they actually do a complete u-turn on a point that may have been accepted for decades before. Any electrical professional has to serve the needs of the Code. Luckily, NEC consultants are available to shed light on the latest 2011 NEC changes. Although these changes have now already been in place for a year, many electrical professionals still haven't quite understood it. They should get prepared since the next changes are set to be released in less than two years. NEC consultants can be found online and they can explain everything to you, from the AFCI and GFCI requirements as well as rules and guidelines about conductor ampacity for instance. As stated, the 2011 National Electrical Code has seen 25 changes compared to the 2008 version. When looking up explanations on these changes online, you should find articles that do a complete analysis of each change, and also explain why it was changed in this way.
Lastly, it should explain to you how these changes may affect you in your professional life. Once you have found an article that meets these needs, make sure you find a quiet place where you will be uninterrupted for a while. Read through each of the changes found in the 2011 NEC and find additional information on any part that you struggle with. Look into anything that you struggle with and make sure you also read the fine print. Hopefully, in doing so, you will feel a lot less overwhelmed with the new national electrical code and you won't actually spend the two years you still have getting to grips with something that won't be valid anymore.
