As3000 Conduit Depth Under Concrete. Stumped by the Code? NEC Requirements for Installing Raceways and Cables Underground EC&M Cat C system is one in which the wiring system is laid within a channel chased in the surface of rock. Electrical conduit underground, concrete at ground entry? Can anyone advise please, is underground conduit normally encased in concrete where it exits the ground to provide protection? Buried 650mm along trench so no issues there but it seems pretty exposed to risk where it has to rise to the surface, hence concrete at the ends.
