Wire sizing is identical. NEC Table 310.16 ampacity values have not changed since NEC 2017. Whether you are wiring in Minnesota or North Dakota, a 20A circuit uses 12 AWG copper and a 30A circuit uses 10 AWG copper. The differences between states are in code enforcement, not in the wire sizing itself.

GFCI requirement differences

Both states enforce NEC 2023, so GFCI requirements are identical. See our kitchen GFCI guide and bathroom GFCI guide for detailed room-by-room requirements.
