A fuse is there to break the circuit if a fault develops in an appliance which has caused too much current flow.<\/p>\n

The fuse itself contains a piece of wire which can easily melt. If the current flowing through the fuse is too great, the wire will heat up until it melts, thus breaking the circuit.<\/p>\n

Fuses in UK plugs are generally fitted with either a 3A or 13A fuse. Any appliance up to 700w will require a 3A fuse to be fitted. Whilst any appliance which is over 700w will need a 13A fuse to be fitted.<\/p>\n

Although manufacturers have now standardised plug fuse ratings to be either 3A or 13A, it is still possible to find a 5A fuse in some older appliances and can still be bought.<\/p>\n

Some loads use a 5A fuse rather than the normal 3A. For instance, in the case of a 500w halogen floodlight a 5A fuse could be used even though a 3A fuse would carry normal operating current. This is due to the large current the halogen light will draw as the cold resistance is lower than the resistance at operating temperature.<\/p>\n

In the case of other appliances it is usual to find either a 3A or 13A fuse fitted to each one. Here are some examples of equipment which would typically use each type:<\/p>\n\n\n\n
