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...
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.
ECT? I am not familliar with that department. It must be for super secret ******* robot alien pirate ninjas only.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)?
It was stated ETC was that too many letters for you?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.
