Likewise, people ask, can you bury IMC conduit?
In the 2017 NEC, a new section was added which requires threaded rigid metal conduit (RMC) or intermediate metal conduit (IMC) for underground wiring. The exception allows PVC conduit, Type RTRC conduit, and Type HDPE conduit where buried under not less than 2 feet of cover.
Also Know, what is IMC conduit used for? Intermediate metal conduit, or IMC, is a rigid steel electrical conduit designed for outdoor exposure and strong connections. It was designed specifically to protect insulated electrical conductors and cables. It does the work of a similar metal conduit, rigid metal conduit (RMC), but weighs about a third less.
Keeping this in view, what type of conduit can be buried?
The National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.
Is IMC rated for direct burial?
UL Listings: IMC is listed to UL Safety Standard #1242. Direct-burial/Concrete Encasement: The UL White Book contains the same installation guidelines for IMC and rigid steel conduit in corrosive environments such as direct-burial and concrete encasement applications.
