The system of plug types using a single letter (from A to N) used here is from World Plugs, which defines the plug type letters in terms of a general description, without making reference to specific standards. Where a plug does not have a specific letter code assigned to it, then it may be defined by the style sheet number listed in IEC TR ...
IEC 60906-1-plug. IEC 60906-1 (IEC designation "Type N") [1] is an international standard designed "to provide a standard for a safe, compact and practical 16 A 250 V AC system of plugs and socket-outlets that could be accepted by many countries as their national standard, even if not in the near future."
Brazil adopted the "NBR 14136" standard, based on IEC 60906-1. South Africa implemented the "SANS 164-5" that also relies on 60906-1, although types D and M are still supported. Both countries are almost a decade with full enforcement of the new standards.
The maximum voltage allowed by the standard is 1000 V DC or AC; the maximum current, 800 A; and the maximum frequency, 500 Hz. The ambient temperature range is −25 °C to 40 °C. [3] There is a range of plugs and sockets of different sizes with differing numbers of pins, depending on the current supplied and number of phases accommodated.
In addition to the obvious physical connector differences (plugs and sockets), AC electric power can be delivered at differing voltage and frequency. Canada, Mexico and the United States all use a 100–127 volt, 60 hertz electrical system, (as do some other central and South American countries), which shares the same physical connectors.
Unique to Switzerland is a three-phase power socket compatible with single-phase plugs: [55] The type 15 plug has three round pins, of the same dimensions as type 12, plus two smaller flat rectangular pins for two additional power phases. The type 15 socket is recessed, and has five openings (three round and two flat rectangular).
Mains electricity or utility power, grid power, domestic power, and wall power, or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world.
