Can somebody tell me where exactly in NEC it says that you have to have a SCCR rating for power distribution blocks?
Per NEC 110.10, I understand that any ?circuit protective device? must have an SCCR rating higher than that which is available, but how about something that is not a ?circuit protective device?? For example, we have a wire way for a backboard, and in that wire way there are lugs or power distribution blocks. Do these lugs or distribution blocks have to have an SCCR higher than that available? Section 110.10 would not seem to apply, since this is not an OCPD. Similarly, how about an enclosure that has only a power distribution block in it; it is not an Industrial Control Panel by definitions, nor is it an OCPD; so does it require an SCCR rating higher than what is available?
