A few years ago, the term “arc flash” crept into our electrical technical vocabulary. Since that time, performing arc flash calculations remains a challenge for many of us. Calculating incident energy ...

Electric shock hazards, including electrocution, have been studied since the introduction of electricity. More recently, however, the dangers of arc flash have come to the forefront of electrical ...

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.
