TYPE L
Type L is used almost exclusively in Italy, Chile, Uruguay and is also randomly found throughout North Africa. (Click here for the full list of all countries that use type L)
The Italian grounded plug/socket standard, CEI 23-16/VII, includes two styles rated at 10 and 16 amps. Both plug top styles consist of three rounded pins placed in a straight line. They differ in terms of contact diameter and spacing, and are therefore incompatible with each other. The 10 amp version has three 4 mm round pins, measuring 19 mm in length. The centres of the line and neutral pins are spaced 19 mm apart. The distance between the centres of either of the two outer prongs and the centre of the ground pin is 9.5 mm. The 10 amp style socket also accepts type C plugs.
The 16 amp version has three 5 mm round pins, measuring 19 mm in length. The centres of the line and neutral pins are spaced 26 mm apart. The distance between the centres of either of the two outer prongs and the centre of the ground pin is 13 mm. Since both plugs are symmetrical, they can be inserted in either direction, which means they are unpolarised.
Nowadays there are also universal sockets available, of which there are two kinds: first, there is the so-called bipasso receptacle (literally: twin-gauge outlet), a very commonly used socket which accepts C plugs as well as both styles of L plugs. Second, there is the Schuko-bipasso receptacle, which even adds compatibility with plug types E & F.
