What an Extension Lead Can Actually Handle
-
Most extension leads are rated for 13 amps maximum
-
That’s roughly 3000 watts in total
-
A single hairdryer can use up to 2000 watts
So yes — even one “small” extension block can become overloaded very easily.
Warning Signs You’re Overloading a Socket
Look out for the following:
-
The plug feels hot
-
The extension cable becomes warm
-
Lights flicker when you switch something on
-
You’ve gathered more plugs in one spot than any socket was designed for
These are early indicators of a serious electrical fire risk.
Safer Alternatives
To avoid overloading your sockets, consider:
-
Installing additional wall sockets
-
Using a high-quality surge-protected power bar
-
Spreading appliances across different circuits
Overloading isn’t just “a bit dodgy” — it’s one of the main causes of household electrical fires, especially in December.
