Fuse (electrical) size of cable so that the limiter clears a fault before the cable insulation is damaged. The Unicode character for the fuse's schematic symbol, found in the Miscellaneous Technical block, is (⏛). A fuse is a safety device 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
Electrical burn Electrical burn An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1,000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. They can exclusively cause surface damage, but more often tissues deeper underneath the skin have been severely damaged. As a result, electrical burns are difficult to accurately diagnose, and many people underestimate the severity of their burn. In extreme cases, electricity can cause shock
