Mains power around the world

Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. Every country has differing rules regarding distribution of electricity for portable appliances and lighting. Voltage, frequency, and plug type vary widely, but large regions may use common standards. Physical compatibility of receptacles may not ensure compatibility of voltage, frequency, or connection to earth ground.
