Key Benefits
When and Why Do You Need 3-Phase?
A standard house runs on a single-phase 100-amp supply. However, commercial kitchens utilizing industrial fryers, massive workshops with metal fabrication lathes, factories with conveyor motors, large HVAC air conditioning arrays, and rapid commercial EV chargers demand voltages and currents far exceeding single-phase capacity. If your current supply cannot meet your demands without constantly blowing the main cut-out fuse, an immediate upgrade to a 400V 3-phase supply is required.
Our Three-Phase Services
We execute massive heavy-duty armoured SWA (Steel Wire Armoured) cable runs traversing factories on robust galvanized cable trays. We install complex Hager or Schneider TPN commercial distribution boards, terminate heavy cores expertly, and crucially—we perform critical phase balancing. Poor phase balancing can cause dangerous voltage drops, overheat neutral conductors, and catastrophically trip main grid breakers, crashing your entire business operation. Our engineers calculate and distribute the load equitably.
