I'm new to this forum and appreciate everyone's help!
I have an installation where we are installing new equipment in a Class II, Div 1, Group G location. Conduit will pass through a wall into a Class II, Div 2, Group G location.
We are installing dust-ignitionproof (NEMA 9) enclosures in the Div 1 location. We are installing dusttight (NEMA 12) enclosures in the Div 2 location. Per 502.15, we are required to seal the conduit between the Div 2 and Div 1 location. Do we only have to seal that (those) conduits passing between the Div 1 and Div 2 locations, or do we also have to seal conduits running between dust-ignitionproof enclosures in the Div 1 location?
Also, where should the seal be installed in the conduit between the Div 1 and Div 2 locations? At the enclosure located in the Div 2 area or at the enclosure located in the Div 1 area? Is there a spacing requirement?
