Abstract :
This paper summarizes arc-flash calculation results in identifying some of the difficulties in translating arc-flash calculations into real-world improvements in safety. This article addresses the following: design considerations, operating considerations, maintenance considerations, and numerous equipment specification issues that can greatly affect the amount of incident energy a worker is exposed to. Arc-flash exposure can often be reduced while electrical designs are still on paper.
