362.12 ENT not for direct earth burial.

Table 300.5 Minimum cover requirements only has columns for:
1. Encasement or other approved raceways for Direct Burial Cables or Conductors
2. Rigid Metal Conduit or Intermediate Metal Conduit
3. Nonmetallic Raceways Listed for Direct Burial Without Concrete
4. Residential Branch Circuits........
5. Irrigation and Landscape lighting.....

If the ENT is not for residential (#4) or for #5 what column would it be under?
 
Is this inside or outside?
Remove the zip-ties, raceways should be straight? Then support it so it doesn't sag. (390.9)
One conduit is supported by plumbing pipe and a zip tie, you gonna allow that?

I like multiple choice quizzes.
 
So they were told this is going to have to be completely encased in concrete since ENT is not allowed to be in direct burial but is OK for concrete encasement which we see all the time. No one cares about what they are strapped to since this is going to be concrete encased along with the plumbing.
 
I bet they fill the hole with dirt up to the conduit, and pour concrete over that. Technically the flex is then not completely encased in concrete ... the bottom is against dirt.
