What causes a circuit breaker to trip?

When I turn on certain appliances, it trips the breaker.


Answer by  Darry (3853)

Circuits are tripped when there is a power overload on that circuit. What this means is either something is drawing more power than the outlet allows or there is a short in the circuit. If it continues to happen you should consult with an electrician.

Also when certain appliances get old. That have motors such as vaccume cleaners and blenders and plug in fans. The motor will over heat causing a fire hazard. This will cause the circuit to trip off as a safety feature.

Well it can trip if the circuit is too old or there is a fault in the circuit. Usually the cause is the latter of the two. I suggest fixing the circuit.

A serge in power will cause the breaker to trip. For example; if you have a microwave and a fridge on the same circuit running at the same time, the breaker will trip because it is a saftey switch.

Well a breaker is like a fuse. When there is too much current being drawn on a circuit it trips breaking the connection before anything gets damaged.
