Frequency and voltage supplied to most premises by country. Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices.
This map reflects the nominal voltage of residential buildings of most countries. In the USA and Canada, there are 2 nominal voltages: 120V and 240V concurrently. This is not a 3 phase system and 240V is not a phase-phase voltage. This system is unique and is only used in certain parts of the world. 230/380V in Europe does not use a similar system.
This list of countries by electrification rate sorts countries by the share of their inhabitants with access to electricity. Access to electricity is considered one of the prerequisites for a modern life. In 2021, 91.4% of the world population had access to electricity.
Saudi Arabia and Mexico have mixed voltage systems; in residential and light commercial buildings both countries use 127 volts, with 220 volts at 60 Hz in commercial and industrial applications. The Saudi government approved plans in August 2010 to transition the country to a totally 230/400-volt 60 Hz system. [8]
Brazil adopted the "NBR 14136" standard, based on IEC 60906-1. South Africa implemented the "SANS 164-5" that also relies on 60906-1, although types D and M are still supported. Both countries are almost a decade with full enforcement of the new standards.
This is a list of electric generation, consumption, exports and imports by country. Data are for the year 2021 and are from the EIA. [1] Figures are in terawatt-hours (TWh). Links for each location go to the relevant electricity market page, when available.
Electricity generation by source and country in 2023 [1] Annual world electricity net generation [2] This is a list of countries and dependencies by annual electricity production. China is the world's largest electricity producing country, followed by the United States and India.
Electrical wiring practices developed in parallel in many countries in the late 19th and early 20th centuries. [7] As a result, national and regional variations developed and remain in effect. (see National Electrical Code, electrical wiring, electrical wiring in the United Kingdom). Some of these are retained for technical reasons, since the ...
