If only one socket in your home has stopped working while others function normally, the cause is often a tripped internal connection, loose wiring, or a minor fault in that specific outlet rather than a full electrical system failure.
Because the rest of the circuit works, the issue is usually isolated.
The Most Common Reasons This Happens
1. Loose or Damaged Wiring
Over time, wires inside a socket can loosen or degrade. If a connection becomes unstable, the socket may stop supplying power.
This is one of the most common causes.
2. Tripped Spur or Internal Protection
Some sockets are part of a spur (a branch off the main circuit). If the internal fuse in that spur fails, only that socket may stop working.
If breakers are also tripping, see:

3. Faulty Socket Unit
The internal components of the socket itself may fail due to wear or overheating.
If you notice warmth or discolouration, avoid using the outlet.
4. Loose Back Box Connection
If the socket was recently installed or moved, the connection at the back of the box may not be secure.
5. Appliance Issue (Not the Socket)
Sometimes the issue is with the device plugged in, not the socket itself.
Test another appliance in the outlet to confirm.
If multiple sockets are affected, see:

Is This Normal?
It may be minor if:
- Only one socket is affected
- The breaker has not tripped
- Other outlets function normally
It may require attention if:
- The socket feels warm
- There is burning smell
- You see visible damage
What You Can Do
If only one socket is not working, you can:
- Test the socket with a different appliance
- Check the breaker panel
- Inspect for visible damage
- Avoid using the socket if overheating is suspected
If the socket remains unresponsive or shows signs of damage, professional inspection is recommended.
