You do have 3 phase equipment maybe those needing those 400 plus volt eq in factory. But in house if TNB just give single phase means we only have certain Max amount of load depending on the Max current through that single phase. Additional phase is just like adding a parallel load sharing thing. Right?


From tnb website:
Single-phase vs. Three-phase Supply
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. 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.
