Idaho Rejects the Adoption of 2011 NEC

According to a recent Code Alert issued on February 2 by the National Electrical Manufacturers Association (NEMA), the Idaho House Business Committee rejected adoption of the 2011 NEC on January 31. Testimony from several electrical contractors and a few homebuilders apparently sealed the deal. The report goes on to say the Board could still take this issue up again later this year, but it highly unlikely to do so. In all likelihood, a vote will not take place again until next year.

Visit the NEMA website for a more detailed analysis of this "non adoption" news.
