Circuit Overloads?
Tripping every time you use the kettle and toaster together? You probably need more circuits.
Understanding Circuit Overloads
Every electrical circuit in your home has a maximum capacity, typically protected by an MCB (Miniature Circuit Breaker) rated at 32 amps for socket rings or 6-20 amps for lighting and radials.
When you try to draw more power than the circuit can handle, the MCB trips to prevent the cables overheating. This is the MCB doing its job - but it's frustrating when it happens repeatedly.
The modern home has far more electrical demands than when most houses were wired. Kitchens in particular often struggle with the number of high-power appliances we now use.
Power-Hungry Appliances
These appliances draw significant power and can easily overload a circuit when used together.
Electric Kettle
2,000 - 3,000W
Toaster
800 - 1,500W
Hair Dryer
1,000 - 2,500W
Electric Heater
1,000 - 3,000W
Microwave
700 - 1,500W
Washing Machine
500 - 2,500W
Tumble Dryer
2,000 - 5,000W
Iron
1,000 - 3,000W
The Maths
A 32A ring circuit at 230V provides about 7,360W maximum. A kettle (3,000W) + toaster (1,500W) + microwave (1,200W) = 5,700W. Add a washing machine running and you're at the limit. This is why modern kitchens benefit from multiple circuits.
How We Solve Overload Problems
Add More Circuits
Split the load by adding dedicated circuits for high-power appliances like cookers, showers, or EV chargers.
Upgrade Your Consumer Unit
A modern consumer unit with more ways allows for better circuit distribution and improved protection.
Install Dedicated Sockets
High-power appliances like washing machines and dishwashers can have their own dedicated radial circuits.
Three-Phase Supply
For very high electrical demands (large properties, workshops), upgrading to three-phase can provide more capacity.
