What colour is a UK domestic 3 amp electrical appliance fuse?
Electrical wiring in the United Kingdom three-phase supplies, IEC 60309 sockets are to be used instead. Many high load non-UK-sourced appliances need IEC 60309 connectors (or wiring via a British Standard "20 A connection unit") in the UK because of the lower plug rating. Flexible appliance cords require protection at a lower current than that provided by the ring circuit overcurrent protection device. The protection device may be contained within the appliance plug or connection unit, and is normally a ceramic cartridge fuse to BS 1362:1973, commonly rated at 3 A (red), 5 A (black), or 13 A (brown), but some accessories and adaptors use a
Fuse (electrical) Fuse (electrical) In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and it must be replaced or rewired, depending on type. Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage
