GOST 7396 - Group C

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 (Type C)

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 Schuko 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 7/5 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 (Type E/F)

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 Europlug is defined here, as is a version of the C 6 (CEE 7/17) plug, but with 4.0 mm diameter pins. The standard allows for the use of devices that draw as much as 6 A with these round variants.

C 6 - CEE 7/17 16 A (Type C)

The standard CEE 7/17 ungrounded plug with 4.8 mm diameter pins is defined here. Note that the GOST standard defines a variant with 4.0 mm diameter pins for use with devices of 6 A or less, which it classifies as a variant shape of the C 5 plug.
