Quizplus · Accepted Answer

Intermediate metal conduit (IMC) and rigid metal conduit (RMC) are essentially the same type of conduit, although they may have slightly different properties or tolerance levels. The difference in their names is primarily due to the thickness of the walls: RMC has a thicker wall than IMC, making it stronger and more durable in some applications. However, both types of conduit are considered to be "rigid" and suitable for use in construction projects, and both are typically listed by the UL.
