Q1 So how far does the Code require the concrete encasement around the non-metallic conduit to be extended in the non-hazardous area from the hazardous area? I'm thinking that we need the encasement just in the hazardous area.
Q2 If the hazardous area is inside a building, say slab on grade, and the PVC is run under the slab. Is the under slab really hazardous?
