Note that American and European
electrical standards differ
considerably. European and British domestic electrical supplies are
single-phase 230V 50Hz, with different sockets types in different
countries (UK 13A, German Schuko, etc.). N American domestic
single-phase supplies are often derived from a centre-tapped 240V
utility transformer with a 120V feed to the domestic sockets.

(Wikipedia). Gives pre 2004 and current wiring colours (particularly
dangerous when mixed in a 3-phase system). Also mentioned is the
ring-main circuit, widely used in the UK but rare elsewhere.
