The terms line voltage/frequency or mains voltage/frequency commonly refer to the electrical voltage and frequency used in the low voltage parts (in particular wall sockets) of an alternating current electricity supply network. These parameters vary between regions, but the voltages are generally in the range 100–240 V, and the two commonly used frequencies are 50 Hz and 60 Hz. Other terms for "mains voltage" include power-supply voltage, supply voltage, system voltage, household power, household electricity, domestic power, wall power, line power, AC power, or grid power.

The lettering system, which is believed to have originated from a U.S. government document^[1], although useful for quick reference is a bit ambiguous in some areas. A plug and socket that are classified here under the same letter will usually mate, but there is no guarantee of this.
