Which appliances can run on single-phase electricity instead of three-phase electricity?

Single Phase Electricity is a form of alternating current system that usually consists of a phase line (live line) and a neutral line (neutral line) with a voltage of 220V or 230V (depending on the region). Single-phase electricity is mainly used in homes, small business establishments, or occasions that do not require a large amount of electricity. Here are a few common appliances that can run on single-phase electricity:


Household appliance


  • Lighting fixtures: such as LED lamps, fluorescent lamps, etc.


  • Kitchen appliances: such as microwave oven, rice cooker, oven, coffee machine, blender, etc.


  • Refrigeration equipment: such as refrigerators, small freezers, etc.


  • Air conditioning equipment: Most home air conditioners use single-phase electricity.


  • Personal care equipment: such as hair dryer, razor, electric iron, etc.


  • Audio-visual equipment: such as television, sound system, DVD player, etc.


  • Computers and related equipment: such as desktop computers, laptops, printers, scanners, etc.



Small office equipment


  • Copier: A photocopier for small offices.


  • Paper shredder: A paper shredder commonly used in offices.


  • Telephone: landline telephone and other communication equipment.


  • Network equipment: routers, switches, etc.



Commercial application


Although commercial sites sometimes use three-phase power to support large equipment, there are many commercial applications where single-phase power is an option to run equipment:


  • POS terminal: point-of-sale system.


  • Small heating equipment: such as small commercial oven.



  • Commercial refrigeration equipment: small commercial refrigerators, display cases, etc.



Agricultural application


  • Water pump: Small water pump for irrigation.


  • Feed processing equipment: such as small crusher.


  • Hvac systems for residential and small buildings


  • Central heating system: Small central heating system.


  • Hot water system: such as electric water heater.



Special application



  • Power tools: such as electric drill, chainsaw and other hand-held power tools.


  • Home washers and dryers: Most home washers and dryers use single-phase electricity.



Matters needing attention


Although the above appliances can run on single-phase electricity, in some cases, if the appliances are more powerful or require a more stable power supply, three-phase power may be required to ensure the best operation of the equipment. For example, large industrial equipment, elevators, large air conditioning systems, etc., typically use three-phase electricity.


In addition, when choosing appliances, it is also necessary to consider the local power supply standards, because different countries and regions may have different voltages and frequencies. In China, the standard voltage of single-phase electricity is usually 220V, and the frequency is 50Hz.


In summary, most household appliances, as well as some commercial appliances, can use single-phase electricity to operate, while three-phase electricity is more used in industrial or occasions requiring higher power loads.

How to Design and Install a Solar PV System?
Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.

Brief Introduction to Thermal Generating UnitsElectricity generation relies on both renewable and non - renewable energy resources. Thermal generating units represent a conventional approach to power production. In these units, fuels such as coal, nuclear energy, natural gas, biofuel, and biogas are combusted within a boiler.The boiler of a generating unit is an extremely complex system. In its simplest conception, it can be visualized as a chamber whose walls are lined with pipes, through which

Why 3-Phase Power? Why Not 6, 12 or More for Power Transmission?
It is well-known that single-phase and three-phase systems are the most prevalent configurations for power transmission, distribution, and end-use applications. While both serve as fundamental power supply frameworks, three-phase systems offer distinct advantages over their single-phase counterparts.Notably, multi-phase systems (such as 6-phase, 12-phase, etc.) find specific applications in power electronics—particularly in rectifier circuits and variable frequency drives (VFDs)—wher
