Power Trip & Tripping Breakers
A power trip that will not stay reset is the single most common emergency call we get. There are four underlying causes, and the right fix depends on which one:
- Overloaded circuit: too many high-draw appliances on one circuit (typically kitchen or aircon). A common HDB scenario is aircon, water heater and kettle on a 20A circuit.
- Short circuit: a live wire touching a neutral or earth wire because of damaged insulation. The breaker trips the instant you reset it, sometimes with a flash or a burning smell.
- Earth leakage: current leaking to earth through a faulty appliance, wet wiring or a degraded RCCB. The RCCB (or ELCB) trips, not the MCB.
- Faulty appliance or plug: a failing water heater, fridge compressor or similar. The trip clears when the appliance is unplugged.
