Also, combining too many appliances in a single outlet either directly or through an extension wire can result in excessive sparking. Blue sparks are good sparks that occurs when the electric current flowing through the outlet reaches towards the plug of the appliance through the tiny gap that remains between them. Violent shaking or ground ruptures can result in power arcing or short circuits from moving or collapsing lines and poles. No moving electrons means no electric current. Other causes include animal or human contact, equipment failures, and conductor slaps. Lightning is another frequent trigger of short circuits and arcs, but in an unusual way.
