I have seen some discussion about fuses in class 1 div 2 areas, but I can find nothing on fuse holders and terminal blocks. I assume that as long as there are no indication features to the blocks and terminal blocks that there is no labeling required to use these items. Ultimately I am looking to use a stqandard NEMA 4 panel in a class 1 div 2 area where all components inside (PLC, DC power supply, pilot lights, pilot operators) are all ready classified and labeled as ok for class 1 Div 2.
