Upgrade or Downgrade Your Electricity Supply

Single-phase vs. Three-phase Supply

Generally, you should change to a 3-phase supply if you have three (3) or more air-conditioners in your home. Upgrading to a 3-phase supply will increase stability and reliability of electricity supply to your premises.
A single-phase meter measures usage from a 230 volt supply through two (2) wires, while a 3-phase meter measures usage from a 415 volt supply through four (4) wires.
You are advised to change from a single-phase supply to a 3-phase supply when your household electricity load exceeds 10kW (or 50A).
