Power trip? Diagnose the right fault first.

Power Trip Singapore: Causes, Safe Reset and Electrician Help

First identify whether one circuit, the whole home or one appliance is causing the trip. Reset only once when there is no heat, smell, smoke, sparking, water or exposed damage; if it trips again, stop and narrow the fault path. Customer-side regulated work is routed to the appropriate licensed electrical worker for the confirmed scope.

Quick answer: what to do when power trips

1. Check for stop signs

If there is heat, burning smell, smoke, sparking, water near electrical points or visible damage, keep clear and use the emergency route. Do not keep resetting.

2. Note the trip pattern

Record whether one MCB, the RCCB/main switch, the whole unit or one appliance drops. A photo is safer and more useful than opening the DB cover.

3. Reset only once if safe

Switch off or unplug likely portable loads if safe, then try one reset. If it trips again, leave the affected circuit or appliance off and arrange diagnosis.

4. Check the supply boundary

If neighbours or common areas also lost power, check building or SP Group outage information. Otherwise prepare the customer-side fault packet.

Power trip electrician quote packet

Send the full DB photo, breaker close-up, one-circuit/whole-home/one-appliance pattern, what was running, whether neighbours also lost power, recent appliance or renovation changes, timing, postal code and any heat, smell, sound, spark or water warning. The coordinator separates utility-supply, appliance, circuit and DB-board paths before confirming the visit scope, regulated-work route and assessment fee.

Frequently Asked Questions

Why does my power keep tripping?

Common paths include one faulty appliance, water ingress, an overloaded circuit, damaged wiring or a protection-device fault. The breaker pattern and a DB photo help narrow the next test.

Does every power trip need a DB upgrade?

No. An appliance or one circuit can cause recurring trips even when the board is serviceable. Diagnose first; use the DB upgrade guide only when board condition or capacity is the issue.

Is it safe to keep resetting the breaker?

Do not keep resetting a breaker that trips again. Unplug suspect appliances if safe, leave wet, hot, burnt or sparking points untouched, and use the urgent electrical route.

What if neighbours also have no power?

Check your building or SP Group outage information first. A neighbourhood or incoming-supply outage is different from a fault inside your unit.

What should I send for diagnosis?

Send the full DB, the breaker that drops, affected rooms, recent appliance or renovation changes, timing, postal code and any heat, smell, sound or water warning.

Power trip decision guide for Singapore homes

Use the breaker pattern to choose the next route; do not assume every trip means the whole DB must be replaced.

Three common paths

One circuit: leave that breaker off and note the affected sockets, lights or fixed appliance.
Whole home: compare your main switch/RCCB state with any building or SP Group outage notice.
One appliance: if the trip follows one plug-in item, unplug it if safe and do not reconnect it for repeated tests.
After rain or a leak: keep clear of wet electrical points and use the urgent route.

When to use another page

For a burnt socket, exposed live part, smoke, heat or total customer-side outage, open the emergency electrician page. For a confirmed old or undersized board, compare the DB box upgrade cost guide. For breaker-only pricing, use the MCB/RCCB replacement guide.
