Question:
What is the min. depth to bury electrical conduct under cement
Jerrell Boner
A
Answer:
Hey Jerrell thanks for your question. It depends on the type of conduit and the location. For up to 1000 volt applications use Table 300.5. Notice in the Notes, cover includes the concrete so rigid metal conduit could be directly under 4 inches of concrete if you meet the conditions in Column 4. If under a street, highway, road, or parking lot there needs to be 20 inches of cover but it does not need to be concrete.
