Fuses and circuit breakers protect circuits and equipment from electrical overload. For example, if the wire leading to the strobe light on the wingtip were to break and end up touching the metal skin of the aircraft, a short would be created which would cause the electrical system to send too much current through the wire. This excessive current would end up melting the fuse or tripping the circuit breaker, cutting off the flow of electricity to that area. Newer aircraft utilize circuit breakers which can be manually reset. However, to minimize the possibility of an electrical fire, a tripped breaker should not be reset unless it is necessary for the continued safety of the flight.
