Have you ever been at home or in the office when suddenly the whole place goes dark?

You check the DB box and see that the main switch has tripped.

You switch it back on, and the electricity comes back as normal. Everything seems fine again.

But after a few hours or a few days, the same thing happens again.

If this keeps happening, do not just keep switching the main switch back on. There may be an electrical problem that needs to be checked.

We use electricity every day. At home or in the office, we depend on lights, air conditioners, water heaters, computers, kitchen appliances and many other electrical items.

Sometimes, electrical problems can happen even when everything has been working normally for a long time.

Why Does the Main Switch Keep Tripping?

There are a few possible reasons why a main switch may trip.

It could be due to electrical leakage, a problem with the wiring, a faulty appliance, a loose cable connection or too many electrical appliances being used at the same time.

The problem is not always easy to see.

For example, all the lights may still work and some power points may have electricity. But when you turn on the air conditioner or another appliance, the main switch suddenly trips.

This can be a sign that something needs to be checked.

Sometimes It Happens Only at Night

Some homeowners tell us that the main switch is fine during the day but trips at night.

This can happen because more electrical appliances are usually being used in the evening.

After coming home, the air conditioner, water heater, TV, washing machine, kitchen appliances and other electrical items may all be switched on.

If the electrical system has a problem, using several appliances at the same time may cause the switch to trip.

If you notice that the switch trips after turning on one particular appliance, let the wireman know. For example, if it happens every time you use the water heater or air conditioner, this information can help when checking the problem.

But do not assume that the appliance is definitely faulty. The problem may also come from the switch, wiring or electrical circuit.

What If the MCB and Other Breakers Look Normal?

Sometimes, homeowners check the DB box and see that the smaller breakers are still ON, but the main switch has gone down.

This does not always mean that the main switch itself is faulty.

The different switches in the DB box have different jobs. The RCCB and MCB help protect the electrical system in different ways.

If there is electrical leakage, an overload or a short circuit, the correct safety switch may trip.

So, simply changing the main switch may not solve the problem.

If the real problem is still there, the new switch may also trip again.

Don’t Keep Resetting the Switch

If the main switch trips once, you may reset it and see if everything works normally.

But if it keeps happening, do not treat resetting the switch as the solution.

Try to remember what happened before the electricity went off.

Were you using the air conditioner?

Did someone just switch on the water heater?

Were many appliances being used at the same time?

Did you hear a buzzing sound from the DB box?

Did you notice a burning smell?

These details can help the wireman when checking the problem.

If you notice smoke, sparks, a burning smell or a very hot DB box, do not touch it or keep resetting the switch. Stay away and get help.

When Should You Call a Wireman?

A small problem like a burnt-out light bulb may be easy to handle yourself if you know how to replace it safely.

But when the problem involves the DB box, RCCB, MCB, house wiring or a switch that keeps tripping, it is better to get a wireman or electrician to check it.

The same applies if you have other electrical problems such as a power point with no power, a loose socket, an air conditioner switch that keeps tripping or a water heater switch that keeps going down.

A wireman can check the DB box, wiring, electrical circuits and related equipment to find where the problem is coming from.

The aim is to find the real problem first before deciding what needs to be repaired or replaced.
