In the high-stakes world of electrical engineering, a short-circuit fault is a race against time. A massive current flows in a fraction of a second, generating intense heat. If a cable can't handle this thermal shock, its insulation can melt, leading to equipment failure, fires, and serious safety hazards. Learn where to get the official PDF and
