Short circuit failure is referred to an electrical device by which the electric current passes directly from the live conductor or phase to neutral or ground in single phase alternating current or polyphase systems.
The short circuit is caused by faults in the insulation of the conductors, because a short circuit can cause significant damage to electrical systems and even building fires, these facilities are usually equipped with magneto thermal fuses or circuit to protect people and objects.

Jorge se encontraba desmontando la fuente de alimentación para proceder a desoldar y volver a soldar una resistencia, una vez terminado se dispuso a volver a monter la fuente de alimentación cuando la quiso probar sin terminar de montarla y ponerla en marcha, entonces los cables internos entraron en contacto con la fuente de alimentación lo que provoco que el fusible explotara y dando lugar a un cortocircuito.
