Does an underground conduit carrying medium voltage cable have to be encased in concrete?

The specs say to bury with sand, but the general says we must use concrete. I don't see anything about this in the NEC...

What is it running under? As long as it is not under a driveway or road you shouldn't. I don't have my codebook on me so I can not find a reference for you at the moment.

MV cable is often in conduit which is sometimes encased in concrete but it is not required. Sometimes the cable is direct buried with no conduit at all.

depends what kind of conduit see art 330.50 and table 300.50 if non metalic see note 2-2 ( yes )depending on listing.My personal opinion is to install conduit on standoffs,encase with concrete,colored,backfill with sand,and metal marking tape.This is too much juice to do the min required.

What not just let the general decide? With a SN like "DEA AGENT" why aren't you posting on an ABC site
(CIA, DIA, NIA, NSA, NDA, FBI, ETC)?

I agree. He isn't asking for red dye slurry, but 3,000 psi concrete. The only problem is that we will eat the cost, but oh well....not that big o' deal.
