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. Whereas type C plugs are very commonly used, this is not the case for type C sockets. This kind of socket is the older and ungrounded variant of socket types E, F, J, K and L. Nowadays most countries demand grounded sockets to be installed in new buildings. Since type C sockets are ungrounded, they are currently being phased out in many countries and replaced by type E, F, J, K or L (depending on the country). A type C plug fits perfectly into a type E, F, J, K or L socket.
