Mains electricity by country has included a list of countries and territories and regions with the plugs, voltages and frequencies which they commonly use to provide electricity to low voltage appliances and equipment or lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Countries may have more than one form of voltage available. For instance, in America most sockets are usually attached to 120 V power supply, but there is also a 240 V power supply available for large appliances. It’s often to see different sockets are mandated for different voltage or current levels.
Plug type, voltage and frequency vary between different country and regions, but large regions may use the common standards. Physical compatibility of receptacles may not able to ensure the compatibility of voltage, frequency, or connection to earth (ground), including plugs and cords. In some countries, older standards may still exist. Foreign enclaves, extraterritorial government installations and buildings with more tourists may supply plugs which not otherwise used in a country, and it’s just for the convenience of travellers.
