I hate the Code book sometimes...
I will ask the Authority having Jurisdiction.
344-10 B (1)
(1) Galvanized Steel, Stainless Steel, and Red Brass RMC, Elbows, Couplings, and
Fittings. Galvanized steel, stainless steel, and red brass RMC elbows, couplings, and fittings
shall be permitted to be installed in concrete, in direct contact with the earth, or in areas subject
to severe corrosive influences where protected by corrosion protection and judged suitable for
the condition.
300-6 A (3)
(3) In Concrete or in Direct Contact with the Earth. Ferrous metal raceways, cable armor,
boxes, cable sheathing, cabinets, elbows, couplings, nipples, fittings, supports, and support
hardware shall be permitted to be installed in concrete or in direct contact with the earth, or in
areas subject to severe corrosive influences where made of material approved for the condition,
or where provided with corrosion protection approved for the condition.
Where ferrous or nonferrous metal conduit has corrosion protection and is judged suitable for
the condition, it may be installed in concrete, in contact with the earth, or in areas exposed to
severe corrosive influence. Special precautions are normally necessary for installing
aluminum conduits in concrete and specific approval by the authority having jurisdiction may
be necessary.
Metal raceways installed in the earth can be coated with an asphalt compound, plastic sheath,
or other equivalent protection to help prevent deterioration. Also, metallic raceways are
available with a bonded PVC coating.
