Wanted to get some others interpretations of concrete encased conduit for branch circuits. I have always interpreted and installed conduit under indoor commercial foot traffic only slabs, based on NEC 300.5. Thereby installing it so it would have the cover of a 4" slab and meet 300.5 under building "0" depth, but recently was told by a former coworker that when Encased in concrete there is no minimum cover required.
Under driveways and parking garages we would also follow table 300.5 based on conduit type.
Searching the forum and other posts it seems to support no minimum burial depth for concrete encased conduit.
First is it correct that there isn't a cover requirement when embedded in concrete.
And second does it mean you could embed conduit in a driveway or road pour without any minimum cover required.
For conduit protection purposes my interpretation of 300.5 always made sense
