Generally,
The terminal blocks of a junction box are usually installed inside the junction box in the terminal block backplate. The main purpose of using a terminal block backplate is to maintain the IP rating of a junction box. I have never experienced an AHJ consider a simple terminal box to be an ICP requiring a separate listing (the box itself must be UL-50 listed). Terminal and distribution blocks all by themselves are not considered part of the “component count” unless there is at least one other actionable component. Power Distribution Blocks (PDB) used in junction boxes are required to be listed according to 314.28(E)(1) and when used in a wireway 376.56(B)(1) Field installed PDB's require covers over live parts.
