I have a 10HP drive that has a sticker on the side that says "Short Circut Withstand 5000A 480V, when protected by fuse UL Class J 40A max"
I also have a 75HP drive that has a sticker that says "Short Circut Withstand 10000A 480V, when protected by fuse UL Class J 175A max"
My question is: what would be the SCCR if the drives are not protected by Class J fuses?
