There are several types of plugs used in Italy (including the Continental European CEE 7/16 plug). However, the official standard is the CEI 23-50. The Italian system is relatively standardized in Libya, Ethiopia, and Chile and is also used in parts of Northern Africa.
The Italian grounded plug/socket standard, CEI 23-50, includes two styles rated at 10A/250VAC and 16A/250VAC and differ in terms of contact diameter and spacing. Because they can be inserted in either direction at random, they are unpolarized. Both carry the Italian safety agency, IMQ, approval.
