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, the department delayed enforcement of the requirements for 250-volt GFCI receptacles and outlet requirements found in NEC 210.8(A) and 210.8(F).
On April 5, 2021, DLI will begin enforcing the 250-volt GFCI receptacle and outlet requirements found in NEC 210.8(A) and 210.8(F). Industry circuit breaker manufacturers have confirmed that supply-chain challenges will be resolved in March 2021. Electrical work authorized by permits issued on or after April 5, 2021, must comply with the 2020 NEC.
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). View electrical laws and rules.
