What are the four types of conduit?

What are the four types of conduit, four common types of conduit are EMT electrical metallic tubing, RMC rigid metal conduit, PVC polyvinyl chloride conduit, and FMC flexible metal conduit, with these being four primary types used in electrical wiring, representing metal thin wall, metal heavy wall, plastic rigid, and flexible metal categories. EMT is thin wall metal conduit used indoors for commercial and residential, lightweight, easy to bend, provides protection and grounding. RMC is heavy wall galvanized steel rigid metal conduit providing maximum protection for industrial and heavy duty. PVC is plastic nonmetallic conduit used outdoors underground and wet locations, corrosion resistant, waterproof. FMC is flexible metal conduit, also called Greenfield or flex, flexible spiraled metal for short runs where flexibility needed like motors. So four types are EMT, RMC, PVC, and FMC, with additional types being IMC intermediate metal conduit, LFMC liquidtight flexible metal conduit, and ENT electrical nonmetallic tubing, but four main types often taught are EMT, RMC, PVC, and FMC, with each serving different applications, with EMT for indoor, RMC for heavy duty, PVC for outdoor underground, FMC for flexible connections, with conduit types selected based on location, need for flexibility, and protection level, with NEC covering all types.
