It can be frustrating when the electricity suddenly goes off while you are at home. You check the DB box and notice that the main switch has tripped. After switching it back on, the electricity comes back and everything seems normal again.
Then you start wondering what caused it. Some homeowners in Puchong notice that this happens when several electrical appliances are being used at the same time. For example, the air conditioner is running, someone is using the water heater, and kitchen appliances are switched on as well.
But is it simply because there are too many appliances? Not always.
Is It an Overload or an Electrical Fault?
When several appliances are running together, the electrical load in the house naturally increases.
However, if the main switch keeps tripping, we should not immediately assume that the house is overloaded. There may be another electrical problem behind it, such as leakage from an appliance, faulty wiring or a problem with one of the protective devices in the DB box.
This is why it is important to check the electrical system instead of guessing.
Why Does the Main Switch Trip?
There are different reasons why a main switch of your DB box may trip.
Sometimes an appliance may have an electrical fault. A water heater, washing machine, refrigerator, air conditioner or another appliance could be involved.
In other cases, the problem may be related to the house wiring or connections. If the wiring is old or there is a damaged connection, it may need to be checked.
There can also be an issue with the DB box or its protective components. The same symptom can have different causes, so an electrician needs to look at the actual situation.
What If the Smaller Switches Are Still On?
A homeowner may open the DB box and see that the smaller switches are still on, but the main switch has gone down. This can be confusing.
The smaller switches and the main protective device do not necessarily respond to every electrical problem in exactly the same way. Therefore, seeing only the main switch trip does not automatically mean that the main switch needs to be replaced.
A proper check can help determine whether the problem is coming from an appliance, wiring, leakage or the DB box itself.
Don’t Just Keep Switching It Back On
If the main switch trips once and you can safely reset it, the electricity may come back as normal. But if it keeps happening, don’t treat it as something you simply have to live with.
Try to remember what was being used before the trip. If it happens when several appliances are switched on, let the electrician know. This can be useful when checking the electrical system.
If you notice burning smell, smoke, sparks, unusual heat or buzzing sounds from the DB box or an appliance, stop using the affected equipment and get professional help.
