Power Trip Repair Cost Singapore [2026]

← Back to Blog

Your circuit breaker trips, the whole flat goes dark, and you're standing in front of your distribution board wondering whether to reset it or call someone. It's one of the most common electrical issues in Singapore homes — and thankfully, one of the more affordable to fix.

On average, power trip repair in Singapore costs $80 to $250, covering the electrician's visit, fault diagnosis, and a straightforward fix like replacing a faulty MCB or tightening a loose connection. More complex issues, like damaged wiring insulation, can cost more. Here's exactly what determines your price — and what you should (and shouldn't) do before the electrician arrives.

Power Trip Repair Cost Singapore 2026

Issue / Service	Estimated Cost
Diagnostic call-out / inspection	$40 – $80 (often waived if you proceed with repair)
Simple fix (loose connection, faulty socket)	$80 – $150
Single MCB replacement	$80 – $150
RCCB / ELCB replacement	$150 – $300
Socket or switch replacement (if that's the cause)	$50 – $120
Full DB box rewiring (for repeated, unresolved trips)	$250 – $1,200+
Same-day / after-hours emergency call-out	+30% – 50% surcharge

Most cases fall on the lower end of this range — a single faulty appliance or worn-out breaker is far more common than a wiring emergency.

What Causes Power Trips in the First Place

Overloaded circuits. Too many high-draw appliances — kettle, aircon, hairdryer — running on one circuit at the same time is the most common cause by far.

A faulty appliance. Something with a short internal fault (often an old kettle, iron, or fan) can trip the breaker the moment it's plugged in.

Earth leakage. Moisture getting into a socket, appliance, or outdoor point can trigger your RCCB/ELCB as a safety measure — this is the breaker doing exactly what it's designed to do.

Ageing or damaged wiring. Insulation that's degraded over time (common in older HDB flats) can cause intermittent trips that get worse over time.

A failing breaker itself. Sometimes the MCB or RCCB is simply worn out and needs replacing, even if nothing else is wrong.

What Affects Your Repair Cost

• How quickly the fault is found. A clear, isolated fault (like one bad socket) is quick to fix. A trip that keeps recurring across different circuits takes longer to trace.
• Time of service. After-hours and weekend call-outs usually carry a surcharge over standard daytime rates.
• Age of your DB box. Original distribution boards from older HDB flats sometimes need a broader upgrade rather than a single-part swap.
• Whether it's a single fix or a pattern. One-off trips are cheap to resolve. Recurring trips across multiple circuits often point to a bigger wiring issue that costs more to properly fix.

What to Do Before Calling an Electrician

1. Unplug everything on the affected circuit. Start with the last appliance you plugged in before the trip.
2. Reset the breaker once. If it holds, plug devices back in one at a time to find the culprit.
3. If it trips again immediately, stop. Don't keep resetting it — that's a sign of a real fault, not a fluke overload.
4. Note what you smell or see. A burning smell, scorch marks, or visible arcing means this isn't a DIY situation — call an electrician right away.

When to Call an Emergency Electrician Immediately

• The breaker keeps tripping even after you've unplugged everything
• You notice a burning smell or see scorch marks near the DB box or a socket
• You see sparking or arcing at any point — do not attempt to reset the breaker in this case
• Only one section of your home has lost power, suggesting an isolated wiring fault
• The power trip happens during or after rain, hinting at water ingress somewhere in the circuit

These situations are genuine safety risks, not just inconvenience — don't wait until morning to get them checked.

How Electricians Diagnose and Fix Power Trips

A professional visit usually starts with isolating which circuit is tripping, then testing individual sockets, switches, and appliances connected to it. If the fault traces to a specific device, that's the fix — sometimes at no extra electrical cost. If it's the breaker itself, an MCB or RCCB swap resolves it. For wiring faults, the electrician will identify the damaged section and either repair or replace it, then test the whole circuit again before calling the job done.

Preventing Future Power Trips

• Avoid running multiple high-draw appliances on a single socket or extension cord
• Get your DB box inspected if it's more than 15–20 years old
• Don't ignore a breaker that "trips sometimes" — it usually gets more frequent, not less
• Keep sockets in wet areas (kitchen, bathroom, outdoor) properly weatherproofed

FAQ: Power Trip Repair Cost Singapore

Is it dangerous to keep resetting a tripping breaker? Yes, if it trips again immediately. That's usually a sign of a genuine fault, and repeatedly resetting it risks fire or shock. Call an electrician instead.

How much does a basic power trip repair cost? Most straightforward repairs — a faulty socket or single MCB — fall between $80 and $200, including the visit and fix.

Will I be charged for the diagnostic visit if I don't proceed with the repair? Policies vary by provider, but many electricians waive or roll the diagnostic fee into the total if you proceed with the fix on the same visit.

Can a power trip damage my appliances? The trip itself is a safety feature protecting your appliances. But repeated or ignored trips can point to wiring issues that, left unresolved, may cause damage over time.

Do I need a licensed electrician for this, or can I fix it myself? Basic troubleshooting (unplugging devices, one reset) is fine yourself. Anything involving the breaker, wiring, or DB box must be done by a Licensed Electrical Worker under Singapore law.

How urgent is a recurring power trip? Fairly urgent. A one-off trip from an overloaded socket is low risk. A trip that keeps recurring, especially with any burning smell, should be checked as soon as possible.
