Single Phase AC Voltage. Most of us are familiar with the single phase voltage in our homes provided by the local utility. For the US, this is typically 120V.

https://en.wikipedia.org/wiki/Three-phase_electric_power

Three-phase electric power is a common method of alternating current electric power ... As compared to a single-phase AC power supply that uses two conductors (phase and neutral), a three-phase supply with no neutral and the ... Three-phase systems may also have a fourth wire, particularly in low-voltage distribution.
