What size is a 13amp fuse?

A 13-amp fuse is typically designed to handle a maximum current of 13 amperes, which is common in household electrical systems in the UK. In terms of physical size, a standard 13-amp fuse, such as those used in plug tops, is usually around 2.5 cm (1 inch) in length and 1.5 cm (0.6 inches) in diameter. It contains a protective wire that melts when the current exceeds 13 amps, interrupting the circuit to prevent damage or fire hazards.
