Installation of a NEMA 4 box (used just for terminations, no arcing or sparking devices) was installed in a Class 1 Div 2 area, mchl cables are leaving from the NEMA 4 box class 1 div 2 area to an unclassified area.
My question is do the cables need to be sealed (packed) at the NEMA 4 box.
Thank you
