Im relatively new to studies learning as I continue school.
When modeling equipment and checking submittals and spec sheets, I often find it hard to locate the SCCR. Does all equipment come with an SCCR? If not, would you use a default of 5k or 10k?
Specifically, at this moment I am modeling some power line filters for a data center job. I dont see any ratings for the power line filters beyond voltage, current, and hertz
what do you do if SCCR is not listed?

I would use 5kA for hardwired devices. I think this is the default value that UL assigns to electronics like VFDs.
