Professional 3-phase power installation services for landed homes, commercial premises and industrial facilities across Singapore. Our EMA-licensed electricians install 3-phase distribution boards, 3-phase wiring, motor connections and assist with SP Group 3-phase supply applications — safely, correctly and to EMA regulations.
Full 3-phase power services — from supply application through to wiring, DB installation, motor connections and fault finding.
Install a 3-phase distribution board for new premises or upgrade an existing single-phase DB to 3-phase, including all circuit breakers, RCCBs, busbars, cable connections and proper earthing — sized and labelled correctly for the load requirement.
3-Phase DBInstall new 3-phase power circuits for heavy equipment, industrial machinery, commercial kitchen equipment, large air conditioning systems and other high-load applications requiring balanced 3-phase power supply.
3-Phase WiringConnect and commission 3-phase motors for pumps, compressors, lifts, industrial machinery and HVAC equipment — including correct DOL or star-delta starter wiring, overload relay setting and phase sequence verification.
Motor WiringAssist with the SP Group application process for upgrading from single-phase to 3-phase supply — advising on load calculation, application documentation, meter box requirements and the electrical works required for the upgrade.
Supply ApplicationDiagnose and repair faults in 3-phase electrical systems — including phase loss, phase imbalance, tripping circuit breakers, overloaded neutral conductors and wiring faults causing equipment malfunction or tripping.
Fault FindingComplete upgrade project from single-phase to 3-phase supply — managing the SP Group supply application, meter box upgrade, new 3-phase main DB installation, and re-circuiting of existing loads to the new 3-phase supply.
Supply UpgradeSingapore's standard residential electricity supply is single-phase 230V — suitable for most household loads. However, commercial kitchens, industrial machinery, large HVAC systems, EV charging and workshop equipment often require 3-phase 400V supply to operate correctly and efficiently.
3-phase power delivers power more efficiently for large loads — the three phases balance each other, reducing current in the neutral conductor and providing smoother power delivery to motors and other equipment. Attempting to run 3-phase equipment on single-phase supply will result in poor performance or equipment damage.
From load assessment to commissioned 3-phase installation.
Assess your total load requirement — equipment ratings, demand factors and diversity — to correctly size the 3-phase supply, DB box, cable and circuit requirements.
Provide a detailed quote covering DB installation, wiring and any SP Group supply upgrade application. Advise on the supply upgrade timeline if 3-phase supply is not yet available.
Install the 3-phase DB box, run all circuits, connect all equipment and install correct overload and RCCB protection — all in accordance with CP5 and EMA requirements.
Verify phase sequence, test all circuits, check load balance and confirm all equipment operates correctly on the new 3-phase supply. Issue test documentation.
Exact pricing after load assessment and site survey.
