Daft question but let me explain.
The tumble dryer is in a brick outhouse, there is a regular extension lead which obviously keeps tripping the box due to overheating. The cable originally was just hanging from house to outhouse so I recently ran it through correct outdoor rated conduit so the cable is now safe and away from the weather.
Now I know full well that in reality there should be an additional ring main to the shed but my other half is looking to move in the near future and I can not warrant the cost and contacting building regs in order to have the additional ring put outside.
Hi, thank you for your product enquiry.
This lead is rated at 13A so will cope with up to 3,120W or 3.12kW of load running through it continuously, which should be more than enough for your tumble dryer by itself.
If your circuit breaker in the main consumer unit in the property keeps tripping though that will be due to an overload of the breaker capacity, not because an extension lead connected to the circuit in question is overheating.
Usually a socket ring circuit breaker will control roughly half of the sockets in a property, either split by floor or down the middle of the property, so the total capacity has to take into account all devices plugged in to any socket on that ring and hence your tumble dryer would not overload the breaker by itself but can be a major contributing factor in combination with all other devices running at the same time.
