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.
