What You Need To Know About Arc Flash

Published by Carelabs (Carelabz) Arc Flash is an energy release that takes place when electricity flows through the air and two live conductors causing short circuit. In a residential setting, arc flashes usually produce little more than a brief flash of light before extinguishing themselves harmlessly. In commercial or industrial setting, voltages are high, soContinue reading “What You Need To Know About Arc Flash”
