The situation is this:
Fifteen 1-1/4" conduits entering horizontally into a Class I Div 2 Group C,D classified area. These conduits are entering halfway up a 20-foot wall.
Are there any NEC issues preventing the conduits entering the rear of a wall mounted NEMA 12 wireway or enclosure, with the sealing fittings located on the end of the conduit stub inside the enclosure?
Sufficient space would be provided around each sealing fitting for filling with sealing compound.
Conduits inside the C1D2 area that serve equipment in the classified area would enter on the top/sides/bottom of this wireway/enclosure.
If no NEC issues, are there any other drawbacks to this arrangement?
