We are setting a row of floor boxes in an existing slab. The GC saw cut the slab, we set the row of boxes and connected with 1" EMT. The inspector says that our EMT is not deep enough. That it must have 6" of cover??? I know on exterior there has to be 6-24" depending upon conditions, but I've never heard of this on an interior slab. What is the code reference on this? I can't imagine that all the highrises I see have no conduit that is less than 6" covered in concrete. Is the inspector correct that we need to cut the slab to a depth to allow 6" coverage?
Any code references appreciated.
Thanks
