China Rigid Metal Conduit—RMC and IMC
1.China Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings.
2.It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment.
3.RMC is sold in 10- and 20-foot lengths and has threads on both ends.
4.Intermediate metal conduit, or IMC, is a thinner, lighter-weight version of rigid metal conduit and is approved for use in all of the same applications as RMC.
Because IMC is lighter and easier to work with than RMC, it is more common in new construction.
