Why Does My Power Trip When I Use Multiple Appliances?

Few things are more frustrating than turning on the kettle or microwave and suddenly losing power. If you have a power trip when multiple appliances are running, it’s your electrical system telling you something isn’t right and it shouldn’t be ignored.

What does it mean when your power trips?

When you experience a power trip, your safety switch or circuit breaker is doing its job. These devices protect your home from electrical overloads, faults, and potential fires by cutting power when the system becomes unsafe.

Common reasons your power keeps tripping

1. Too many appliances on one circuit
Modern homes use far more electricity than older systems were designed for. Running appliances like air conditioners, kettles, ovens and washing machines at the same time can overload a circuit.

2. Outdated switchboards
If your home has an older switchboard with ceramic fuses or limited circuits, it may not handle today’s power demands.

3. Faulty appliances
A damaged cord, internal fault or water exposure can cause an appliance to trip the safety switch as soon as it’s turned on.

4. Electrical faults
Wiring issues, damaged power points or moisture can all cause repeated tripping.

Is it dangerous?

Yes, frequent tripping is a warning sign. Resetting the switch repeatedly without fixing the cause increases the risk of electrical fires and damage to your appliances.
