What to do when a Circuit Breaker Trips
When the lights suddenly go off generally your first thought is that there has been a power outage. But only your house has no power and when you check other parts of the house the power is still on there. The likeliest thing is that a circuit breaker has tripped. Most of the time this isn’t something you need to call an electrician about. A house circuit breaker tripping is a very common occurrence. All you need to do is follow these simple steps. That’s how to turn the power back on.
Main Reasons for Power Tripping
If it is dark, the first thing to do is find a torch or use your phone’s flashlight mode. You really don’t want to mess around inside your fuse box if you can’t see what you are doing. The next thing to do is to turn off and unplug all the appliances on the circuit that isn’t working. The two main reasons why you get an electricity trip are a circuit overload or a short circuit.
A circuit overload just means that you are running too many appliances at once and trying to draw more power than the circuit can provide. It’s pretty obvious that this is the cause of your problem if the power has tripped when you have put on way more things than usual, such as the toaster, an electric frypan, the kettle and a blender all at once while the fridge is running. Some circuits can handle this, but older homes can struggle with excess demand.
A short circuit is usually caused by faulty appliances. That’s why the first thing to do is turn them all off at the socket and unplug them. Now it’s time to visit the fuse box. There are various places where this can be – outside, in the laundry or even in the garage. Mostly it houses both the switchboard and the meter, so people also call it the meter box or simply the switchboard. What you should see inside is a number of switches or breakers. The breaker that has switched off is the one that controls the circuit that has gone dead. Just turn it back on.
All should be well and the power to that circuit should come back on. If it doesn’t, and the breaker immediately trips again, it means the short circuit is in the system. That is something for an electrician to sort out. But otherwise, all you will have to sort out from here is which the offending appliance is. Finding out which appliance has caused the problem is simply a process of trial and error – plug an appliance in, turn it on and if it results in a tripped breaker then it’s the culprit.
