Flickering lights, tripping breakers, dead sockets or a complete power failure — electrical faults don't announce themselves at convenient times. Our EMA-licensed electricians diagnose the root cause accurately and fix it safely for HDB flats, condos, landed homes, offices and commercial premises across Singapore.
Electrical faults in Singapore homes and businesses range from minor nuisances — a flickering light or a single dead socket — to serious safety hazards such as arcing wiring, a burning smell from the distribution board, or a complete power failure. Getting the diagnosis right is critical: addressing the symptom without finding the root cause leads to repeat faults, wasted money, and real fire risk.
Our EMA-licensed electricians carry professional diagnostic equipment — clamp meters, insulation resistance testers, loop impedance testers and thermal imaging cameras — to accurately pinpoint faults. Every job is carried out in full compliance with SS 638 (Code of Practice for Electrical Installations) and EMA regulations, with a documented service report provided on completion.

From minor nuisances to serious hazards — here are the most frequent electrical faults we diagnose and resolve across Singapore every day.
A breaker that trips repeatedly is trying to protect you. Common causes: an overloaded circuit (too many appliances), a short circuit (wiring fault), a ground fault, or a faulty MCB/RCCB that needs replacing. We identify which and fix it properly.
🔴 High Risk — Act PromptlyFlickering lights can indicate a loose connection at the fitting, a failing LED driver, voltage fluctuations, or a loose neutral wire in the DB box. Persistent flickering often signals a wiring fault that can cause arcing and fire.
🟠 Moderate RiskA socket that has stopped working may have a blown fuse (if switched), a tripped dedicated breaker, a wiring fault behind the wall, or a failed socket mechanism. We test, diagnose and replace cleanly.
🟡 Check RequiredIf power is out in part of your home, the issue may be a tripped MCB, blown fuse, a neutral wire fault, or a wiring fault in that circuit. A full outage may be SP Group related or a main switch/DB fault.
🔴 High Risk — Act PromptlyA burning plastic smell or visible sparks from a socket, switch or DB box is a fire risk emergency. Turn off the circuit immediately and call us. Causes: overheating wiring, loose connections arcing, or a failed component.
🔴 Emergency — Call ImmediatelyWater and electricity are a dangerous combination. Flooding, a leaking pipe above a socket, or moisture in the DB box can cause short circuits, ground faults and electric shock risk. We safely test and restore affected circuits.
🔴 High Risk — Act PromptlyThe DB box is the nerve centre of your electrical system. Humming sounds, heat, or a burning smell from the DB box, outdated fuse-wire DB, or non-functional breakers require immediate professional inspection.
🟠 Moderate RiskA switch that does nothing may have a wiring fault, a failed switch mechanism, or a problem with the neutral feed at the switch location. We diagnose at the switch and trace back to the DB if needed.
🟡 Check RequiredIf you experience a mild tingle or shock when touching an appliance or socket, there is likely a ground fault or missing earth connection. This is a genuine safety hazard requiring immediate attention.
🔴 Emergency — Call ImmediatelyA sudden spike in electricity consumption without a change in usage pattern can indicate a faulty appliance with a hidden short, or deteriorating wiring with high resistance causing energy waste and heat.
🟡 Investigation NeededIf your RCCB (Residual Current Circuit Breaker) trips whenever a specific appliance is plugged in, that appliance has an earth leakage fault. We identify which appliance and advise on repair or replacement.
🟠 Moderate RiskProperties wired before the 1990s may have rubber-insulated cable, aluminium wiring, or no earth protection — all non-compliant with current SS 638 standards and a significant safety risk. We assess and rewire.

Some electrical symptoms require you to act now — switch off the affected circuit at the DB box and call a licensed electrician before attempting any DIY investigation.
A structured, safe approach that finds the actual cause of your electrical fault — not just the obvious symptom — so the fix holds permanently.
Call or WhatsApp us describing the symptoms — tripping, flickering, dead sockets or burning smell. We advise on immediate safety steps while booking your visit.
Our electrician arrives with full diagnostic equipment and carries out a systematic visual and instrument inspection of all affected circuits and components.
Using clamp meters, insulation resistance testers and loop impedance testers, we isolate the exact fault location — not just the symptom location.
Before any repair work begins, we present a clear written quote covering parts, labour and completion timeline — no hidden charges, no surprises.
All repair or replacement work is carried out with the affected circuit safely isolated, following SS 638 procedures and using approved materials.
After repairs, we re-energise the circuit and perform full electrical tests — insulation resistance, earth continuity and RCD trip-time — before sign-off.
The distribution board (DB box or consumer unit) is the control centre of your electrical system. All the circuit breakers and protection devices live here. Knowing the key components helps you understand what your electrician is diagnosing when a fault occurs.
Protects individual circuits (lighting, sockets, aircon) from overload and short circuit. Trips automatically and can be reset. Replace if it no longer holds or trips without cause.
Detects earth leakage current (ground faults) as small as 30mA and disconnects the circuit. This is your primary protection against electric shock. Should be tested monthly.
Provides both overload/short circuit protection AND earth leakage protection in a single device — increasingly common in modern Singapore DB boards.
The master switch that disconnects all circuits from the SP Group supply. Must be accessible and clearly labelled. Switch this off first in any emergency.
The earth bonding system that provides a safe return path for fault current, protecting people from electric shock. Must be intact and correctly connected to all circuits.

"My circuit breaker kept tripping every evening. Two other electricians just reset it and said it was fine. This team ran a proper insulation resistance test, found a wiring fault in my kitchen circuit and repaired it. Problem solved — completely."
"Called at 10pm because of a burning smell from our DB box. Electrician arrived in under 45 minutes, identified a loose busbar connection that was arcing, and made it safe that night. Absolutely professional emergency response."
"Our new office had a power point that kept tripping the RCCB whenever the espresso machine was plugged in. They found the machine had an internal earth fault and advised us to get it repaired rather than replacing the circuit. Saved us money."
"Had an old fuse-wire DB board in my resale flat. They replaced the entire board with a modern MCB/RCCB consumer unit, added proper circuit labelling and tested everything. The whole job took half a day and the price was very fair."
"Lights in half our house stopped working after a heavy rainstorm. They diagnosed a water-damaged junction box above the ceiling, replaced the box, re-terminated all connections properly and waterproofed the area. Very thorough."
"Our shopfront sign kept tripping the breaker. They found the sign had a failed driver causing intermittent short circuits, replaced the driver unit, and re-wired the sign circuit with a dedicated MCB. No more tripping."
