Electrical Troubleshooting / Power Trip
Power Trip Diagnosis in Singapore
Power trip diagnosis starts from $80 at SG QuickFix. When the RCCB or an MCB keeps tripping, the cause is traced to a faulty appliance, a damp socket or light, or the wiring, usually within 30 to 90 minutes. If it trips again straight after a reset, leave it off; the RCCB is warning of a leak to earth.

Task guide
When this may be needed

What the team does
The technician checks which device tripped: the RCCB points to earth leakage, an MCB to overload or a short circuit. Appliances are unplugged and circuits are tested one by one to see which one causes the trip. Insulation tests narrow it down further to an appliance, a socket, a light or the wiring. You are told the cause, simple fixes are done, and anything else is priced before repair.

FAQs
An RCCB trips when current leaks to earth, usually from a faulty appliance, water in a socket or light, or damaged wiring. If it trips with nothing plugged in, the wiring needs checking.
Moisture makes small leaks to earth worse, so outdoor sockets, lights and wiring near windows often show faults in heavy rain.
If neighbours are also out, call SP Group's 24-hour hotline on 1800 778 8888. If only your home is affected and it keeps tripping, the fault is inside your home.
