Multi-standard socket-outlets

Socket-outlets that take a variety of plug types can be found in where market size or local market conditions make a specific plug standard impractical to implement. Socket-outlets may accept plugs to various European, Asian, North American, British or Australian standards. Multi-standard socket-outlets do not safeguard against devices being damaged by the wrong voltage. Users must know the voltage requirements of their appliances as well as the prevailing local voltage. Some devices are compatible with a wide range of voltages and frequencies.

These socket-outlets have one or more ground holes to allow 3-pin plugs. On properly wired circuits, the ground contact will be connected to earth ground. They may not provide grounding to all types of plugs, as is the case of Schuko or French plugs where the grounding pin that mates with the plug is part of the socket-outlet rather than the plug.
