For questions dealing with 240 volt electrical circuits, devices, and equipment. This tag covers the similar voltages as well (i.e. 220, 230, etc), since they generally refer to the same thing. Use with the [electrical] tag.
240 V is a common voltage used in residential electrical systems. In some parts of the world (most notably Europe), 240 V is provided for all receptacles. In the United States (and those countries who use the 120 V US standard) it is achieved by using both ungrounded (hot) legs of a 120/240 V single split phase system. This voltage is sometimes referred to as 220 V and 230 V as well, due to the changing of voltage standards over time (see this question for a fuller explanation).
Many larger electrical appliances use 240 V, including
