The common UK plug – Is generally fitted with a 3A or 13A fuse. For appliances up to 700w you need to use a 3A fuse. And for appliances over 700w you need to use a 13A fuse.Here are some common examples:
3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron
13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron
Manufacturers have now standardised plug fuse ratings to be either 3A or 13A. However, 5 Amp fuses are still used in some older equipment and are available to buy.
