It ist able to supply ample power for most smaller customers, including homes and small, non-industrial businesses. Single-phase loads may be connected to a three-phase system. It should be distributed evenly between the phases of the three-phase system for efficient use of the supply transformer and supply conductors. supply transformer and supply conductors.

Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors. A single-phase supply connected to an alternating current electric motor does not produce a revolving magnetic field.es not produce a revolving magnetic field.
