Sparking Outlet: Is it Dangerous? Why are there sparks? A sparking outlet can be dangerous under many circumstances. If the spark only occurs when you plug in a piece of equipment that begins to run immediately then the spark is likely to be caused by the electricity jumping the gap as the pins connect into the socket. If the sparking occurs under normal operation with or without equipment connected then there is definitely something to be worried about.
