Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase). The latter is better suited for powerful appliances. A single-phase connection is common in small to medium sized houses that use an average amount of electricity. Three phase connections are more common in larger houses that utilise a lot of electricity, or in rural areas.
What’s the difference between single phase and three phase electricity?
