Determine arc flash boundary

http://wiresizecalculator.net/calculators/arcflashcalculator.htm WebThe arc flash hazard analysis should determine the arc flash boundary (AFB) and level of personal protective equipment (PPE) that the worker must wear. The arc flash boundary is based on voltage, the available fault current and the time it takes for the upstream protective device to operate and clear the fault.
