Top 5 Dangerous Short Circuit Videos

A high current fault can create an electrical fire by forming a high-energy electric arc that quickly vaporizes the metal and the insulating material. An electrical explosion is the sudden release of energy due to a short circuit between the power phases or an earth phase.
It is important to realize that a large amount of energy is available on the bus of most electrical panels when they operate within the normal design parameters. For example, a short circuit from one phase to another on a 400 A panel, 120/208 volts can instantly release more than 100 kilowatts of power during a fault condition and not burn the protection fuse or circuit breaker.
