Household electricity supply
Single-phase meter
Measures usage from a 230 Volt supply through two (2) wires
3-phase meter
Measures usage from a 400 Volt supply through four (4) wires
WHEN TO CHANGE
You are advised to change from a single-phase supply to a 3-phase supply when your household electricity load exceeds 10kW or 50A. As a rule of thumb, if you have three (3) or more air conditioners in your home, you should upgrade to a 3-phase supply as it will increase stability and reliability of electricity supply.
