Are RMC and GRC the same?
Metal. Rigid metal conduit (RMC) is a thick-walled threaded tubing, usually made of coated steel, stainless steel or aluminum. Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded.

What are rigid couplings?
Rigid couplings are designed to connect two shafts together so that no relative motion occurs between them (see Fig. 7.16). Rigid couplings are suitable when precise alignment of two shafts is required. If significant radial or axial misalignment occurs high stresses may result which can lead to early failure.

What is most commonly used to cut RMC and IMC?
Installation usually requires large pliers or pipe wrenches. IMC can be cut with pipe cutters or a band saw, but you must file the interior side of the pipe to remove any sharp burrs that might damage the outer coating of the wire as it is being pulled through the conduit.
