In Norway electricity, rather than gas, is commonly used for cookers and stoves (komfyr), as well as heating water. 25A - 230V flat pin stove plugs and sockets can be found in nearly each home.
25A plugs are 'downsized' to 16A Schuko (CEE 7/4) when induction cooktops are installed.

CEE 60309 is the common standard for industrial applications, but older types of three-phase plugs with four of five flat pins are still available for repair.
