Differences Between the Minnesota and North Dakota Electrical Codes
Minnesota and North Dakota have similar electrical codes, but there are some subtle and important differences. This article covers some of the differences between the states, and some anachronisms of some of the local codes in Grand Forks and Fargo.
Adoption and Editions
Every three years, the National Fire Protection Association (NFPA) publishes a new edition of the National Electrical Code (NEC), with the most recent edition published in 2023. Contrary to popular belief the NEC is not in itself a legal document. It is a recommendation of best safety practices by the NFPA. Minnesota typically adopts the most recent edition the July after it is published, whereas North Dakota has chosen to remain on the 2020 NEC for this cycle. Both states have adopted their respective electrical codes with exceptions. For example, in ND they do not require that exterior, hardwired outlets that supply air conditioning equipment have GFCI protection. The reason for this is the startup power inrush tends to trip the GFCI, causing the air conditioner to not come on, which is a potential life safety issue.
Local Amendments
Cities in both Minnesota and North Dakota have full say in what their local code additions are. They are allowed to have additional requirements based on whatever issues the city has had in the past. For example, the City of Fargo mandates that only two NM cables can pass through a single hole in wooden studs. The City of Grand Forks also has their own rules, but mainly follows the NEC and State Electrical Board guidelines. Additionally, cities are permitted to form their own inspection and licensing department. In North Dakota, the cities of Grand Forks, Fargo, Bismarck, and Minot have these, and in Minnesota, most of the metro area cities have their own permitting departments as well as Duluth and Mankato.
