Type N is used almost exclusively in Brazil.
The type N socket and plug are the official standard in Brazil. The plug consists of two pins and a grounding pin. There are two variants: the prongs of the 10 A version have a diameter of 4 mm and a length of 19 mm. The second version, rated at 20 amps, is used for heavier appliances and has 4.8 mm round pins, but also measuring 19 mm in length. The centres of the line and neutral pins are spaced 19 mm apart. The centre-to-centre distance between the earth pin and the middle of the imaginary line connecting the two power pins is 3 mm.
