You have a device (SCCR 5000A) on a branch circuit with standard circuit protection (say 20A, 1pole breaker, 10+ kA Interrupting rating)
Can you use an inline fuse to protect the device with an interrupting rating of ...say something like 1000 or 2000 A?
Where does the NEC cover something like this?
