I have available fault current of 60kA. I have engineer that tells me he will provide 100kA fuse but the downstream panelboards 10 feet away he will provide 22kA because manufacturer install instruction says let through current of the fuse is 14kA. See attached let thru current. The fuse is 600A 3 poles JM60600-3CR.
Would 22kA be sufficient or he should be providing 100kA?
