2. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   A three-phase motor is more compact and less costly than a single-phase motor of the same voltage class and rating, and single-phase AC motors above 10 hp (7.5 kW) are uncommon. Three-phase motors also vibrate less and hence last longer than single-phase motors of the same power used under the same conditions. [26]

3. Mains electricity by country - Wikipedia

   277/480 V 347/600 V 60 Hz NEMA 5-20R outlets, which are similar to type B but have a T-shaped neutral slot, are sometimes used for higher current 120 V equipment (up to 20 A). Homes are typically provided with 120/240 V split-phase power; NEMA 14-30R and 14-50R receptacles are provided on 240 V circuits for clothes dryers and electric stoves.

4. Phase converter - Wikipedia

   en.wikipedia.org/wiki/Phase_converter

   An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

5. Polyphase system - Wikipedia

   en.wikipedia.org/wiki/Polyphase_system

   One voltage cycle of a three-phase system. A polyphase system (the term coined by Silvanus Thompson) is a means of distributing alternating-current (AC) electrical power that utilizes more than one AC phase, which refers to the phase offset value (in degrees) between AC in multiple conducting wires; phases may also refer to the corresponding terminals and conductors, as in color codes.
