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.

World Plugs includes some history, a description of plug types, and a list of countries giving the type(s) used and the mains voltage and frequency. Although useful for quick reference, especially for travellers, IEC World Plugs may not be regarded as totally accurate, as illustrated by the examples in the plugs section below, and errors may exist.
Like in most European plugs, the power pins of Danish plugs are 19 mm (0.75 in) long and spaced 19 mm (0.75 in) apart, with a diameter of 4.8 mm (0.19 in). The earthing pin is part of the plug (in contrast to French and Schuko plugs); it is D-shaped, 14 mm (0.55 in) long, and offset from the power pins by 13 mm (0.51 in).
AC circuits adopted the same form during the war of the currents, allowing lamps to be run at around 110 V and major appliances to be connected to 220 V. Nominal voltages gradually crept upward to 112 V and 115 V, or even 117 V. [citation needed] After World War II the standard voltage in the U.S. became 117 V, but many areas lagged behind even ...

The EmPower universal AC outlet is compatible with power plugs from over 170 countries and is designed such that 110 V AC power is not present at the outlet until a suitable plug is fully inserted. The AC EmPower system converts aircraft 400 Hz AC or wild frequency power to standard 60 Hz AC.
