Why do Circuit Breakers Trip?

If all the appliances and lights along a single circuit go dark simultaneously, it’s likely that the circuit has tripped/burned out. Circuit breakers automatically shut off the power to the circuit wiring if something goes wrong. With circuit breakers, all you have to do is locate the one that has tripped on the main panel and reset it to the “on” position. However, it is vital to understand why the circuit breaker has tripped, to avoid it from happening again.

In very rare cases, the breaker itself may have become damaged and will need replacing. However, in most instances, the fitting is just doing its job when it trips. A circuit breaker is designed to trip and turn off the power in case any of the following situations occur:

  • Overloaded Circuit- An overloaded circuit is one of the commonest reasons for a circuit breaker trip. This happens when that circuit draws a higher electrical load than it is designed to carry. When you operate too many light fixtures or appliances at the same time, the wiring in the circuit heats up; the circuit breaker senses this and the mechanism trips, breaking the flow of electricity and shutting off the electricity.
  • Short Circuit– This is a far more serious than an overloaded circuit and can cause breaker tripping. When a hot wire touches a neutral wire it can cause a short circuit. However, there are times when the circuit wiring isn’t the culprit at all; it may be caused by a wiring problem in a device/appliance that has been plugged in a socket in that circuit; this is what makes it pretty challenging to diagnose and fix a short circuit problem.
  • Ground Fault– This is also a type of short circuit; It occurs when any hot wiring touches timber framing members or comes in contact with metal wall boxes. A ground fault can be pretty dangerous when it occurs in areas with that have high moisture levels like bathrooms and kitchens.

Very happy with the great service and professionality! Mohammed was very patient and meticulous, going (quite literally) above (our deck's roof) and beyond to find and fix problems with some existing bad wiring. Explained all the problems in a very clear and informative way. Would highly recommend this service to friends and family!

"I would highly recommend Karl and his team for any work his professionalism and dedication to his work is remarkable.

We are currently building a 225sqm complex extension in Strathfield and he has continuously offered great advice on how to proceed with all things electrical from led lights and power points to HDI cables for the TV. He has always been on time and has gone above and beyond expectation. He and his team even worked 10hrs on a day that was 45 degrees. Once again I would highly recommend Karl"
