UK FUSE BOX RATINGS
Fuse Rating - Judge Electrical Limited
Fuse rating = (Power/Voltage) x 1. OR, put another way: Fuse rating = (watts/volts) x 1 . Note the power of the appliance – usually in the appliance manual, Note the voltage (240 volts in the UK). Use the next highest fuse rating after the calculation. Say the calculated fuse rating is 2 amps, use a 3 amp fuse.
Fuse Boxes Explained | Electrical Safety First
Fuses (may be found in place of circuit breakers) – rewirable fuses have a piece of special fuse wire running between two screws. When a fault or overload current flows through the fuse wire, it will become hot and melt. The melted fuse breaks the circuit, disconnecting the faulty circuit and keeping you safe.

As a rule of thumb, fuses are rated according to the power rating of the appliance. If you have to replace a fuse, it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating. A common UK plug is generally fitted with a 3A or 13A fuse.
