This is an overview of mains electricity by country, with a focus on listing the regional differences in plug and socket types, nominal supply voltages, and AC supply frequencies commonly used for delivering electrical power to low-voltage appliances, equipment, and lighting typically found in homes and offices. Voltage and frequencyMains electricity varies in voltage and AC frequency across the world. In some cases plugs from one region may fit sockets of another, but physical compatibility of receptacles may not ensure compatibility of voltage, frequency,. Those with an A/B form thus represent phase-to-neutral (A) and phase-to-phase (B) voltages respectively, with the exception of 120/240 and 110/220.
