 Top Code Changes: 2011 NEC

Code News Update


On May 26, the governor of Nebraska approved Legislative Bill 56 (LB56), which will update 81-2104(5) to reference the minimum standards for electrical wiring to be the 2011 National Electrical Code. This change will go into effect Aug. 27, 2011. Any electrical permit received by the division on or after that date will be based on the 2011 NEC; existing permits will remain on the 2008 NEC. In addition, future electrical exams will be based on the 2011 NEC, beginning with the Norfolk exam scheduled to take place on Sept. 20, 2011.

According to a recent Code Alert issued on June 8 by the National Electrical Manufacturers Association (NEMA), the state of South Dakota voted to adopt the 2011 NEC, with several exceptions, one of which clarifies the use of nonmetallic sheathed cables in: one- and two-family dwellings and accessory structures; multifamily dwellings, farmsteads, and accessory structures; and other structures. The effective date for this change is July 1, 2011. Visit the NEMA website for additional details on this adoption news.
