Power Keeps Going Off in One Room – Possible Causes

If the power keeps going off in one room, it can be confusing and frustrating—especially when the rest of your home still has electricity.

This type of issue is known as a partial power outage, and it usually indicates a problem with a specific circuit rather than the entire electrical system.

While some causes are minor, others may require urgent attention from a qualified electrician.

Why Would Power Go Off in Only One Room?

Homes are wired with multiple circuits, each responsible for powering specific areas.

If one circuit fails, it can affect:

• A single room
• A group of plug points
• Lighting in a specific area

This is why you might lose power in one room while the rest of the house continues working normally.

Common Causes of Power Loss in One Room

Tripped Circuit Breaker

One of the most common causes is a tripped breaker in your DB board.

This can happen when:

• Too many devices are running on one circuit
• A faulty appliance causes a surge
• There is a short circuit or overload

If your breaker keeps tripping, you should read our guide on Why Does My Circuit Breaker Keep Tripping? to understand the root causes.

Loose or Damaged Wiring

Loose wiring connections can interrupt the flow of electricity to a specific area.

This can result in:

• Intermittent power
• Complete power loss in one room
• Flickering lights

Loose wiring is a serious safety risk and should be inspected by a professional.

Faulty Plug Socket or Light Circuit

A damaged plug socket or light fitting can disrupt power to part of a circuit.

Signs include:

• Burn marks on sockets
• Smell of burning plastic
• Power loss when using certain plugs

If you notice a burning smell, see our guide on Burning Smell from Plug Socket – What It Means for more details.

Overloaded Circuit

If too many devices are connected to one circuit, it may overload and shut down.

Common causes include:

• Multiple high-power appliances
• Extension cords with several devices
• Continuous heavy electricity usage

Overloading can also cause flickering lights. You can learn more in our article on Why Are My Lights Flickering? Causes & Solutions.

Faulty Appliance

A single faulty appliance can disrupt power in a room.

To test this:

• Unplug all devices
• Reset the breaker
• Plug appliances back in one by one

If the power cuts when a specific appliance is used, it may be defective.

Is This Problem Dangerous?

Yes, it can be.

While a simple breaker trip may not be dangerous, other causes such as loose wiring or short circuits can increase the risk of:

• Electrical fires
• Damage to appliances
• Electrical shocks

If the issue happens repeatedly, it should be taken seriously.

What Should You Do If Power Keeps Going Off?

If you lose power in one room, follow these steps:

1. Check your DB board for a tripped breaker
2. Reset the breaker once
3. Unplug appliances in the affected room
4. Avoid overloading sockets
5. Monitor if the issue happens again

If the problem continues, do not keep resetting the breaker repeatedly.

When to Call an Electrician

You should contact a professional electrician if:

• The breaker trips repeatedly
• Power loss happens frequently
• You notice burning smells or sparks
• Lights flicker before power cuts
• There are signs of damaged wiring

If you’re experiencing these issues, it may be time to consult a licensed electrician in Pretoria to inspect your system safely.
