single-phase

Residential power type

Single-phase describes electrical power delivered through a single alternating current, the standard form supplied to homes and small businesses: single-phase wiring, a single-phase motor.

The term contrasts with three-phase power, which uses three currents and serves industrial applications requiring heavier loads.
