with the Soviet standard plug installed. Because of that, many of the Russian plugs found their way into other Eastern European countries. One peculiarity of the Soviet standard is the use of an ungrounded plug with 4.0 mm diameter pins for 6 A and a corresponding socket that would not accept the 4.8 mm diameter pins of devices that could draw as much as 16 A. These sockets were sometimes modified by enlarging the holes of the plastic (

The series includes the following standards: * GOST 7396.1-89 Plugs and Socket-Outlets for Household and Similar Purposes - Basic Dimensions * GOST 7396.2-91 Plugs and Socket-Outlets for Household and Similar Purposes - Particular Requirements for Fused Plugs - General Technical Specifications

Group C

Group C connectors are various CEE 7 plugs used in continental Europe, with allowances made for various Soviet era plugs that are compatible with them. Note that in Soviet-era construction the 16 A versions may be supplied with only a 10 A service. ; C 1 2-pin ungrounded 6 A and 16 A :Both varieties of this connector use two pins with centers spaced 19.0 mm apart. The 6 A variety has pins on the plug with a 4.0 mm diameter with the corresponding socket holes having a diameter of 4.5 mm. The corresponding dimensions on the 16 A are 4.8 mm and 5.5 mm respectively. Thus a 6 A plug fits into both varieties of this socket, but the 16 A plug does not fit into the 6 A socket. The 16 A socket will accept all group C plugs, but does not provide grounding. ; C 2 CEE 7/4 Schuko 16 A (Type F) :This is the standard

connector used in much of continental Europe. The Schuko plug will fit into the 16 A variety of the C 1 socket, but will not be grounded. ; C 3 CEE 7/6 French 16 A (Type E) :This is the standard connector found in France, Belgium, Poland, Czech Republic, and Slovakia. The plug will fit into the 16 A variety of the C 1 socket, but will not be grounded. ; C 4 CEE 7/7 16 A :This is the compromise plug designed to be accepted and to be grounded in both the Schuko and French sockets. The plug will fit into the 16 A variety of the C 1 socket, but will not be grounded. ; C 5 CEE 7/16 Europlug 2.5 A (Type C) :The standard
