(used in all countries of Europe except the United Kingdom, Ireland, Cyprus and Malta)
This two-wire plug is ungrounded and has two round prongs. It is popularly known as the europlug which is described in CEE 7/16. This is probably the single most widely used international plug. It will mate with any socket that accepts 4.0 - 4.8 mm round contacts on 19 mm centres. The plug is generally limited for use in class II applications that require 2.5 amps or less. It is, of course, unpolarised. It is commonly used in all countries of Europe except the United Kingdom and Ireland. It is also used in various parts of the developing world.
used almost exclusively in India, Sri Lanka, Nepal and Namibia)
India has standardised on a plug which was originally defined in British Standard 546 (the standard in Great Britain before 1962). This plug has three large round pins in a triangular pattern. It is rated at 5 amps. Type M, which has larger pins and is rated at 15 amps, is used alongside type D for larger appliances in India, Sri Lanka, Nepal and Namibia. Some sockets can take both type M and type D plugs.
Although type D is now almost exclusively used in India, Sri Lanka, Nepal and Namibia, it can still occasionally be found in hotels and theatres in the UK and Ireland. It should be noted that tourists should not attempt to connect anything to a BS546 round-pin outlet found in the UK or Ireland as it is likely to be on a circuit that has a special purpose: e.g. for providing direct current (DC) or for plugging in lamps that are controlled by a light switch or a dimmer.
used almost exclusively in South Africa, Swaziland and Lesotho)
This plug resembles the Indian type D plug, but its pins are much larger. Type M is rated at 15 amps. Although type D is standard in India, Sri Lanka, Nepal and Namibia, type M is also used for larger appliances. Some sockets over there can take both type M and type D plugs. Type M is also used in Israel for heavy appliances such as air-conditioning circuits (in cases where wall-mounted units are plugged in to a dedicated socket) and certain types of washing machines.
