Protection from arc faults
An arc flash can be many thousands of degrees and cause injuries from minor burns through to severe lacerations and even blindness. Image: Shutterstock. AN arc fault can be spontaneous, due to a breakdown of the conductors phase to phase or phase to neutral; ground or inadvertently bridging electrical phases; or contacts with a conductive object. The result is a sudden release of electrical energy (incident energy) through the air and a massive electrical explosion. The arc flash is the blinding light and intense heat that can result. In the arc it could be many thousands of degrees in temperature more than four times hotter than the surface of the sun, and in the plasma cloud (ionised gas) that erupts,…
