  2. Mains electricity by country - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity_by_country

    (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volt transformer. This system is able to concurrently provide 240 volts and 120 ...

    en.wikipedia.org/wiki/Mains_electricity

    The United States and Canada use a supply voltage of 120 volts ± 6%. Japan, Taiwan, Saudi Arabia, North America, Central America and some parts of northern South America use a voltage between 100 V and 127 V. However, most of the households in Japan equip split-phase electric power like the United States, which can supply 200 V by using ...

  4. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    North American transformers usually power homes at 240 volts, similar to Europe's 230 volts. It is the split-phase that allows use of 120 volts in the home. Japan's utility frequencies are 50 Hz and 60 Hz. In the electricity sector in Japan, the standard voltage is 100 V, with both 50 and 60 Hz AC frequencies being used. Parts of the country ...

    en.wikipedia.org/wiki/Distribution_transformer

    Connecting a load between the hot wire and the neutral gives 120 volts, which is used for lighting circuits. Connecting both hot wires gives 240 volts for heavy loads such as air conditioners, ovens, dryers, and electric vehicle charging stations. In Europe and other countries using its system, the secondary is often the three-phase 400Y/230 ...

    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.

    The most common three-phase system will have three hot legs, 208 V to each other and 120 V each to the neutral. An older, but still widely used, high-leg delta system uses three phases with 240 volts phase-to-phase for motor loads, and 120 volts for lighting loads by use of a center-tapped transformer; two of the phases are 120 volts to neutral ...

    Seven countries including Germany, the Netherlands and France pledged on Monday to eliminate CO2-emitting power plants from their electricity systems by 2035. Taken together, the countries account ...

  9. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    The voltage measured between any line and neutral is called phase voltage. [4] For example, in countries with nominal 230 V power, the line voltage is 400 V and the phase voltage is 230 V. For a 208/120 V service, the line voltage is 208 V and the phase voltage is 120 V.
