Electrical Socket Overload Calculator

Most people have extension leads in their home or office, using a 4 way extension cable is a simple, easy and affordable way to increase the number of appliances that they can plug into a single wall socket.

However, although there is space to plug in up to four appliances, this does not mean it is always safe to do so. To avoid the risk of overloading the extension lead which in turn can cause overheating and possibly fire, you should never plug multiple appliances into an extension lead that when combine use more than 13 amps.

Use the Electrical Safety Council calculator to plug in some typical household appliances to see the effect on the load, and to get useful tips on how to avoid overloading your sockets.
