Electrical codes and standards
2020 NEC update
The Board of Electricity adopted the 2020 National Electrical Code (NEC) with an effective date of Nov. 17, 2020. Accordingly, the Department of Labor and Industry began enforcing the 2020 NEC on Nov.17, 2020. Electrical work authorized by permits issued on or after this date must comply with the 2020 NEC. Electrical license examinations are based on the requirements of the 2020 NEC beginning Jan. 1, 2021.
However, due to concerns regarding the availability of 2-pole GFCI circuit breakers, until further notice, the department is delaying enforcement of the requirements for 250-volt GFCI receptacles and outlet requirements found in NEC 210.8(A) and 210.8(F).
GFCI circuit breakers may be commercially available, but the COVID-19 pandemic has created major manufacturing and supply-chain challenges, thus limiting the availability of these devices and the ability to complete work and obtain inspections. Section 90.4, of the NEC allows the authority having jurisdiction to refer to the most recent previous edition of the NEC adopted by the jurisdiction when materials are not yet available at the time the Code is adopted.
Chapter 1315 of the Minnesota State Building Code adopts a national standard for the installation of electrical wiring, apparatus and equipment for electric light, heat, power, technology circuits and systems, and alarm and communication systems. Minnesota's electrical code consists of the National Electrical Code (NEC) as published by the National Fire Protection Association (NFPA).
