The difference between above ground and below ground conduit is their fire-resistant qualities.
Above ground conduit has fire resistance per CSA C22.2 No. 2515 and UL 2515 standards. These standards require that the above-ground conduit will self-extinguish within 15 seconds after each of five successive flame applications per the UL 94 (vertical) flame test standard.
Below ground conduit meets UL 94 (horizontal burn) requirements, which are less strict than vertical burn requirements. A few similarities between Above ground conduit and below ground conduit are colors, dimensions, physical and mechanical properties are the same. Although above-ground conduit has a higher flame resistance, its suitable and can be used for below-ground applications as well.
