Question: Is it true that when looking at fault currents, you will have a higher avaliable fault current for a lower voltage than you would for a higher voltage? For example you will have a higher fault current at 240V then you will at 480V?
No, that is not true. The available fault current is inversely proportional to the voltage. Therefore, you will have a lower fault current at 240V than you will at 480V. Flag for review
