Single phase and three-phase power are power supply connection systems with different power levels to suit different electrical needs.
Single-phase power is generally used in residential homes where the electrical equipment and systems are smaller and have lower energy needs.
Three-phase power is suited to workshops, large buildings and larger homes with many large energy-intensive appliances.
Most residential homes run effectively on single-phase power. Generally, if you‘re unsure which type of power connection have in your home it's likely to be single phase.
A quick way to check is to go to your meter box and look at the fuse cartridges. If you have one main switch or fuse cartridge, you have a single-phase connection. If you have three, you have three-phase power.
