Just as Hercules was escaping with the cattle and bringing it back to Eurystheus, a bull got loose at Rhegium and jumped into the sea. The bull swam to Sicily and then made its way to the neighboring country. The native word for bull was italos, and so the country came to be named after the bull, and was called Italy.
Part of the Data center management glossary: An arc flash is an undesired electric discharge that travels through the air between conductors or from a conductor to a ground. The resulting explosion can cause fires and serious harm to equipment and people.
WHAT IS ARC FLASH. An Arc Flash is very simply, an electrical short circuit through air. Whether it occurs from phase to ground or phase to phase doesn't matter. What does matter is that enough energy is present to perpetuate the arc. Lightning is an example of arc flash as is an electric arc welding machine. The difference between them is that lightning discharges itself in a very short period of time whereas an arc welding machine sustains the arc indefinitely. Either way, you don't want to get too near either of them.
